Spec corrections
Product specs drift: generations change, old numbers get copied between sites, and listings outlive the hardware they described. When current primary data conflicts with what is circulating, we document it here with sources and a verification date. Each entry links the review where the full spec check lives.
Costway Relaxation 09 · Wall clearance · verified August 20, 2026Current primary value: Costway publishes no engineering figure. Its Overview block says five inches and its Key Feature block says two inches, on the same product page, and the spec table carries no clearance row at all. Still circulating: Five inches, repeated by dealers who took the first of the two numbers. Plan for the larger number and measure with the chair fully reclined before you commit to a wall. A two-inch claim on a chair that slides forward as it reclines is the kind of figure a room layout cannot absorb if it turns out to be wrong.Costway Relaxation 09 · Auto program count · verified August 20, 2026Current primary value: Five, mapped key by key in the manual: Ache Relieve, Comfort, Demo or Relax, and two further presets on the controller. Still circulating: Six automatic modes in the product page Key Feature block, against five auto massage modes in the Overview block above it, and three massage techniques on Costway’s own blog against five in the manual. Take the manual, which enumerates the keys rather than counting for a bullet list. The technique count is five, and the blog is the outlier at three.Costway Relaxation 09 · Where the 28 airbags actually sit · verified August 20, 2026Current primary value: Four in the upper arm, eight in the arm and sixteen in the legs, which is the manual’s own breakdown and accounts for all 28. Still circulating: Shoulder, arm, calf and feet, per the product page. Expect arm and leg compression rather than a full-body squeeze. Foot rollers are real and separate from the airbags, so the feet are worked mechanically rather than by air.Costway Relaxation 09 · What the chair is made of · verified August 20, 2026Current primary value: PVC, PA, steel parts and electrical parts, per the manual’s own specification page. Still circulating: PP, ABS, iron, PU leather and sponge pad, per the retail spec table. Unresolved, and worth asking about. PVC and PU are different upholstery materials with different wear behaviour, and steel and iron are not interchangeable in a frame claim.Costway Relaxation 09 · Warranty length and what it covers · verified August 20, 2026Current primary value: Three years flat, covering parts and labour with no component tiering, with in-home service and Costway paying parts shipping. The instrument is printed in the in-box manual. Still circulating: Ten years structural and ten years bodywork, stated by a Canadian dealer that also sells its own plan excluding labour and on-site calls. The factory term is the good news on this chair and it beats several machines costing three times as much. Grepping the manual for the word lifetime returns nothing, and the tiered lifetime warranty in circulation belongs to a different Costway model.Costway Relaxation 09 · What the page tells a search engine about its own score · verified August 20, 2026Current primary value: 4.36 from 21, which is what the widget renders to a person reading the page. Still circulating: 4.8 from 17, which is what the same page emits in its structured data for a search engine to read. We publish neither as a rating, because a seller-hosted score is not our judgement and never will be. It is recorded because a page sending a higher number to machines than to humans is a data-integrity fact about the seller.Costway Relaxation 09 · Where the 330 lb capacity comes from · verified August 20, 2026Current primary value: 330 lb, published in Costway’s retail spec table alongside a user height range of 4.92 to 6.23 feet. Still circulating: Nothing in the manual. The in-box document states no weight capacity at all, while its warranty exclusions void coverage for use over weight capacity. The retail figure is the only one, so buy on 330 lb. Note that a published height range is more than most chairs in this bracket offer, and that this one is genuinely generous at both ends.Costway Relaxation 09 · The model code · verified August 20, 2026Current primary value: JL10009. Costway publishes four different identifier strings for the one chair across its own surfaces, and two different manufacturer part numbers in two countries. Still circulating: JL10014, a code in circulation that we could not find in any listing anywhere. JL10009, retail SKU JL10009WL, in black and brown. Anything written from a JL10014 premise is describing a chair that does not exist.
Human Touch Super Novo · Wall clearance · verified August 20, 2026Current primary value: Four inches behind the chair, stated twice in the maker’s own manual: once in the setup instructions and again in the specification table. The manual separately asks for 24 inches of clear floor in front for the footrest. Still circulating: Two inches, in Human Touch’s own press material and repeated across the channel. Plan on four inches. The manual is the document that ships with the chair and it states the figure twice, while the two-inch number appears only in marketing.Human Touch Super Novo · Whether this is a 3D or a 4D chair · verified August 20, 2026Current primary value: A 3D roller chair that ships three programs branded 4D. The manual’s own back-intensity control is labelled 3D, and it defines the 4D programs as variable-speed routines rather than as a fourth mechanical axis. Still circulating: 4D, used flatly across dealer listings and editorial coverage as if it described the mechanism. The rollers move on three axes. That is not a criticism of the chair, and buying it expecting a fourth axis of depth control that the maker never claimed would be a mistake.Human Touch Super Novo · Published user height range · verified August 20, 2026Current primary value: None. Fifty-four pages of manual contain no minimum and no maximum user height, and the maker’s live product page for this generation is gone. Still circulating: A five foot to six foot nine inch fit window, repeated across the channel, and a 320 lb capacity quoted by one selling reviewer. We publish neither. A capacity figure that is really the weight of the crate is the clearest example on this site of how a number acquires authority by repetition.Human Touch Super Novo · What the five-year warranty actually covers · verified August 20, 2026Current primary value: One year of in-home service, three years of parts, five years of structural framework. The maker’s current warranty page still lists this chair by name in that tier. Still circulating: Five years of in-home service, five of parts and five of structural, advertised by one dealer, and a flat five-year warranty stated by another with no tier breakdown at all. Human Touch’s own advice article names parts-only-after-the-first-year as a warranty red flag, which is a description of its own Super Novo tier. Freight on warranty parts is the owner’s, and total warranty service is capped at the original purchase price.Human Touch Super Novo · Whether a used one carries any warranty · verified August 20, 2026Current primary value: No, on two independent grounds. The instrument is non-transferable and applies only to the original purchaser, and it separately excludes products bought from unauthorized resellers, third-party marketplace sellers, liquidation sales or private sellers. Still circulating: Listings that carry the five-year warranty language onto secondhand and refurbished units. Treat a used original as an uncovered purchase and price it accordingly. This is the single most useful thing to know about the chair in 2026.Human Touch Super Novo · Track type · verified August 20, 2026Current primary value: Not stated in the manual, which describes the massage functionally and publishes no track length. Still circulating: A combined S-track and L-track architecture, asserted in the maker’s press releases and repeated as a specification. The coverage the marketing describes is plausible and undocumented. Where a track figure appears in a listing for this chair, it did not come from Human Touch.
Human Touch WholeBody 8.0 · Whether the 8.0 replaces the 7.1 · verified August 20, 2026Current primary value: It does not. Human Touch sells four WholeBody chairs side by side, and the 8.0 and 7.1 are two of them. They share a chassis, the same width, the same 114 lb weight and the same 285 lb load rating. Still circulating: The newest chair in the line and an upgrade over the 7.1, as retailer copy describes it. Buy the 8.0 for its silhouette, its glide mechanism and its extra programs, not because it supersedes anything. Anyone assuming a higher number means a higher tier will pick the wrong chair.Human Touch WholeBody 8.0 · Zero gravity · verified August 20, 2026Current primary value: Not claimed by the maker for this chair. Its own comparison chart sets the recline option for both the 8.0 and the 7.1 to standard recline, and reserves zero gravity for a different sibling. Still circulating: Zero-gravity recline, attributed to the 8.0 by dealer listings. If a zero-gravity position is the reason you are buying, this is not the chair in the line that offers it.Human Touch WholeBody 8.0 · Upright dimensions · verified August 20, 2026Current primary value: Unresolved between two maker figures. The Use and Care Manual gives 48 inches long by 28 wide by 44 high upright, while the product page and the sell sheet agree with each other on a different set. Still circulating: The product-page and sell-sheet figures, which two maker documents carry against the manual’s one. Measure generously and confirm with the seller before ordering. What is not in dispute is the rear clearance, which every maker document puts at 9 inches.Human Touch WholeBody 8.0 · Maximum user weight · verified August 20, 2026Current primary value: 285 lb, consistent across the manual, the sell sheet and the product page, and identical on the sibling chair. Still circulating: 265 lb, published by two dealers. The maker’s figure is the one to buy on, and it is one of the few specs here that every Human Touch document agrees about.Human Touch WholeBody 8.0 · Track type and airbag count · verified August 20, 2026Current primary value: Neither is published. A search of all six maker documents for track, S-track, L-track, a depth rating or any track measurement returns nothing, and the words airbag, air bag and air cell return a literal zero. Still circulating: Track and airbag specifications appearing on retail listings for this chair. This chair is described by the maker in terms of what it does rather than what it contains. Treat any track length or airbag count you see for it as unsourced.Human Touch WholeBody 8.0 · What the endorsement mark means · verified August 20, 2026Current primary value: An endorsement, not a certification and not a regulatory clearance. It is the only third-party mark on the sell sheet, and it carries no safety-testing meaning. Still circulating: A safety certification, which is how a mark on a sell sheet reads at a glance. Report it as an endorsement. The maker also attaches an explicit disclaimer that no medical claims are warranted or implied, which we take at face value and repeat here.
iRest A306 · Who warrants this chair · verified August 20, 2026Current primary value: A dealer, not the manufacturer. We could not locate an iRest-issued warranty instrument for the US market on any iRest-controlled domain, and the chair’s own manual contains no warranty section at all: its contents run safety, components, function, usage and legal notices, and stop. Still circulating: A manufacturer warranty, promised by a dealer banner reading full manufacturer warranty, and a one-year labour, three-year parts, five-year frame breakdown that circulates widely. Get the selling dealer’s warranty in writing and read it as the whole of your coverage, because that is what it is. The widely repeated frame and labour breakdown appears in no document we could open; the third-party reviews that state a term all state a bare three years and nothing more.iRest A306 · Published fit range · verified August 20, 2026Current primary value: None. The manual publishes no user height limit and no weight capacity, and neither does the one reachable brand storefront. The only statement about body size is that the legrest extends. Still circulating: Up to 330 pounds with a stated height window, from an editorial review, against a different pair of limits from a second review. We publish neither. One of those reviews shipped with literal placeholder text where its specifications should have been, which is a fair measure of how carefully the numbers in circulation were assembled.iRest A306 · Rated power · verified August 20, 2026Current primary value: 120 W, in the specification table of the maker’s own operation manual. Still circulating: 150 W, in the technical specifications table of the one reachable iRest brand storefront. Take the manual, which is the document that ships with the product. The gap is small in practice and it matters because it shows the two maker surfaces are not synchronised.iRest A306 · What else the manufacturer does not publish · verified August 20, 2026Current primary value: No dimensions upright or reclined, no chair weight, no shipping weight, no airbag count, no track length and no product code. The manual describes airbags functionally, as three modes and three intensities, and never counts them. Still circulating: Full specification tables on dealer and editorial pages carrying track lengths, airbag counts and dimensions. Every number in circulation for this chair is a retail number. That is not automatically wrong, and none of it can be checked against the manufacturer.iRest A306 · Which chair the name refers to · verified August 20, 2026Current primary value: SL-A306, with regional configurations suffixed. Parts sellers treat the suffixes as non-interchangeable: one lists a remote as fitting the 48 configuration exclusively. Still circulating: A306 and A306 Pro used as if they named one product, across brands, with the same chair also sold under two other badges. We could not confirm from any maker source which configuration ships to the US. Check the suffix on the label before ordering a part, because a remote for one configuration is described as not fitting another.
Kahuna LM-6800T · Warranty structure · verified August 20, 2026Current primary value: Two years of full parts and labor with on-site repair, per the LM-6800T warranty certificate, conditional on registering within one month of delivery. Still circulating: A straight downgrade from the family three-year warranty, as widely repeated and as our own earlier review put it. The headline number went down while real coverage in years one and two went up. We had this wrong in our first review and have corrected it. The condition that actually costs owners money is the 30-day registration deadline, which voids everything if missed.Kahuna LM-6800T · Roller capability behind the 3D+ badge · verified August 20, 2026Current primary value: Four rollers on an SL track with position, width and six speed settings; the 22-page official manual documents no depth adjustment anywhere. Still circulating: A 3D+ label in the product title, escalated to 3D and 4D language in some marketplace copy. Judge this chair as a good quad-roller SL track and ignore the plus sign. Nothing in the maker own documentation supports adjustable roller depth.Kahuna LM-6800T · User weight and height rating · verified August 20, 2026Current primary value: No model-specific rating exists. The only official figures are a series-wide footnote recommending 5 feet to 6 feet 2 inches and up to 220 pounds, plus FAQ statements. Still circulating: Third-party review figures that run considerably higher, including 285 pounds with a 5 foot to 6 foot 4 range, alongside live listings that publish no capacity at all. Shop against the series footnote, not the dealer numbers, and treat 6 feet 2 inches as a real ceiling. A 6-foot-5 owner reported the upper airbags could not reach him.Kahuna LM-6800T · Auto program count at retail · verified August 20, 2026Current primary value: 24 auto programs, named menu by menu in the official manual. Still circulating: 12 auto programs, as the main live dealer specification table states. The chair has 24. If a listing says 12, it is describing the previous generation.
Luraco i9 Max Plus · Robotic engines on the base trim · verified August 20, 2026Current primary value: One 3D Butterfly engine and 14 motors on the base i9 Max Plus. Still circulating: Dual Butterfly rollers, as our own earlier review and much of the channel described the base chair. The comparison chart governs. The base chair has one engine. We corrected our own review, which had carried the SE figure since publication.Luraco i9 Max Plus · Chair weight · verified August 20, 2026Current primary value: 280 lb for the base trim, 310 lb for SE, Billionaire and Royal, per the comparison chart. Still circulating: About 310 lb series-wide, per the manual's Table 3 and all four product pages. A 30 lb gap decides whether two people can carry it upstairs. We publish the per-trim figures from the chart and flag that the manual disagrees.Luraco i9 Max Plus · Minimum user height · verified August 20, 2026Current primary value: No published minimum. The manual's Table 3 and the comparison chart both state only "up to 6 feet 10 inches". Still circulating: A 4 foot 7 inch floor on one product-page bullet; 4 foot 10 or 4 foot 11 on the distributor site and one dealer. We publish the range as documented up to 6 foot 10 with no reliable published minimum. A question about the floor is drafted for Luraco and not yet sent, so no answer is represented here. Buyers under about 5 foot should confirm fit with a dealer rather than trust any of the three floors in circulation.Luraco i9 Max Plus · Structural frame warranty · verified August 20, 2026Current primary value: Not an affirmative coverage grant. The i9 Max Plus coverage table has three columns only: In-House Service, Parts and Leather. Still circulating: Five years of structural frame coverage, as our own earlier review and several dealers state it. We corrected our own review, which had listed frame coverage as a benefit. Buyers should not expect a frame repair entitlement from this document.Luraco i9 Max Plus · Scope of the 10-year leather warranty · verified August 20, 2026Current primary value: Ten years against tearing only. The table column reads Leather 10 Years, Guaranteed No Tearing. Still circulating: A flat ten-year leather warranty in the brochure, and a blanket "All i9 Max Plus Series chairs have a 10-Years Warranty" headline; Luraco's live warranty page omits leather from its covered list entirely. The three marketed numbers are accurate as written. The gap is in the unstated qualifier, so we publish the qualifier alongside the headline.Luraco i9 Max Plus · Voice response languages · verified August 20, 2026Current primary value: Seven, including German, per the product page, brochure and manual. Still circulating: Six, dropping German, in the comparison chart and in the spec table on the maker-branded retail page; one dealer substitutes Chinese for German. Seven is supported three documents to one, so we publish seven and note that Luraco's own chart says six.Luraco i9 Max Plus · Track length and track name · verified August 20, 2026Current primary value: 60 inches, consistent across the manual, the comparison chart and every dealer that publishes a figure. Still circulating: A buyer who escalated to BBB reported measuring roughly 43 inches; Luraco answered in writing that the track is 60 inches per its product documentation. Both parties are describing different measurements. We publish 60 inches as the documented path length and state plainly what a tape measure down the backrest will show, because that gap is what produced a five-figure dispute.Luraco i9 Max Plus · Patent count · verified August 20, 2026Current primary value: Ten granted patents named in the manual and in the product page notice, plus six pending. Still circulating: Nine awarded in the same product page's prose, eleven in the brochure, twelve US entries plus a Canadian design patent on the patents page, and seven at two dealers. We publish the manual's enumerated list, since it is the only figure backed by the actual patent numbers, and we note that the count varies by document.Luraco i9 Max Plus · FDA status · verified August 20, 2026Current primary value: Registered and listed. Establishment registration and FEI 3006737652 active for 2026, one device listing under product code ISA, Class I, exempt from premarket notification. Still circulating: FDA Listed as a medical device at one editorial outlet, and a marketing line pairing FDA Registered with medical benefits in a company press release. We publish registered and listed, never cleared and never approved, and we explain that the missing 510(k) is the normal posture for a Class I exempt device rather than a gap.Luraco i9 Max Plus · Generation number · verified August 20, 2026Current primary value: The product page calls the series the 9th Generation of iRobotics. Still circulating: The user manual's title line calls it the 10th Generation. We report both and attach neither to a buying argument. A question about which is correct is drafted for Luraco and not yet sent.
MassaMAX MD306 Pro · Which warranty covers this chair · verified August 20, 2026Current primary value: None that we could find. The distributor enumerates its covered models by number, and the list runs A688, A710 Pro, A665, A580, MT339, MT398, MD321, MD906, MD908, A303, A305 and A306. MD306 is absent from it, and a raw-HTML string search of the warranty page returns zero occurrences of the model number. Still circulating: A three-year limited warranty, restated on marketplace listings, on a third-party warranty-help site, and by comparison pages that carry a MassaMAX warranty row. The three-year structure is real and consistently described, so this chair may well receive it in practice. What does not exist is a document saying so. One telephone call to the seller could settle it, and until the answer is in writing this is a chair with no documented manufacturer warranty.MassaMAX MD306 Pro · Whether A306 and MD306 are the same chair · verified August 20, 2026Current primary value: They are treated as different chairs by the seller. A306 has a manual, a pre-owned SKU, a maker video and a place on the covered-model list. MD306 has none of those. Still circulating: Listing copy and search results that use MD306 Pro, A306 Pro and A306 as if they named one product. Do not accept an A306 or MD906 document as evidence about this chair. The designation MD306 Pro appears in marketplace listing titles and, as far as we could read, nowhere the manufacturer controls.MassaMAX MD306 Pro · Published user weight and height limits · verified August 20, 2026Current primary value: Neither is published for the 306 series. We read both storefronts, the warranty schedule, the pre-owned A306 record and the A306-28 operating manual, and found no user height range and no weight capacity for this family. Still circulating: A 300 lb capacity with a 5 foot 2 inch to 6 foot 1 inch height range, which are the sibling MD906’s published figures, and a Canadian dealer’s 260 kg maximum user weight. There is no fit figure for this chair worth publishing. Carrying the MD906 numbers across would be inventing a specification, and the metric block is arithmetically impossible as printed.MassaMAX MD306 Pro · Track length · verified August 20, 2026Current primary value: Not published for the 306 series anywhere we could read. Still circulating: 53.15 inches, which is the figure the maker publishes for the MD906. The rail is marketed as SL and no length belongs to this model. A track figure lifted from a sibling is the single easiest way for a fabricated spec to enter circulation.MassaMAX MD306 Pro · What the paid warranty extension covers · verified August 20, 2026Current primary value: Parts, with labour excluded. The body of the warranty page says so and the extension’s own product record agrees, adding shipping coverage the warranty page never mentions. Still circulating: One hundred per cent of parts and labour with no deductible, stated in the Warranty FAQ four paragraphs below on the same page. Assume labour is excluded and get the answer in writing before paying. The instruments also never state a purchase window, an eligible model list, or whether the two years run from purchase or from expiry.MassaMAX MD306 Pro · Where the manufacturer publishes anything · verified August 20, 2026Current primary value: Nowhere under its own brand name. massamax.com returns a 114-byte parked-domain stub on every path we tested, so there is no first-party catalogue, no spec page and no warranty page under the brand. Still circulating: Search results that still index massamax.com product URLs with live-looking titles, one of which pairs a 4D model title with an SL-track A306 slug. Everything documentary for this brand lives on its distributor’s Shopify storefronts, which are editable HTML pages rather than dated documents. That is why three of them have drifted apart, and why no versioned warranty a buyer can hold exists at all.
MYNTA M1612 · Whether the warranty reaches this chair · verified August 20, 2026Current primary value: Unresolved, and the wording works against it. MYNTA publishes one brand-wide instrument scoped to SL-track massage chairs, all models, naming no model numbers. It defines the covered consumer as the original purchaser from the Mynta store and separately excludes products bought from unauthorized resellers. Still circulating: A three-year MYNTA warranty, repeated across listings and by the site that presents itself as the brand’s official website. A warranty that requires you to buy from a store that does not stock the chair is the central risk here. Put the question to MYNTA in writing before ordering, because no document we found answers it.MYNTA M1612 · What three years of coverage actually means · verified August 20, 2026Current primary value: Three years of parts only. Labour, in-home service, field service and shipping are all one year, and from month thirteen the remedy is a free part in the post. Still circulating: A flat three-year limited coverage, which is how the brand describes it in its own product copy for a sibling model. Read the table, not the sentence. There is no published technician network, no claim portal, no case system and no phone number, so year two is you, a shipped part and an email thread.MYNTA M1612 · What the manufacturer publishes about the chair · verified August 20, 2026Current primary value: Nothing. MYNTA hosts no manual, no spec sheet, no brochure and no downloadable document of any kind, for this model or any other, and publishes no specification table on any massage-chair product page. Still circulating: A 330 lb capacity, a 6 foot 3 inch height ceiling and a 7-inch extendable footrest, all traceable to a single site. Treat every published M1612 specification as unverified. The maker’s own warranty tells owners to consult their product user manual for model-specific detail, and no such manual exists on any property it controls.MYNTA M1612 · Weight capacity · verified August 20, 2026Current primary value: No manufacturer figure exists. Still circulating: 330 lb from the affiliate site, 260 lb from an editorial review that names no model, and 300 lb from a listing for a different MYNTA chair. Do not buy this chair on a weight figure. If capacity is the constraint that decides your purchase, the absence of a maker number is itself the answer.MYNTA M1612 · Who the warrantor is · verified August 20, 2026Current primary value: Undetermined. The instrument names MyntaChair as the responsible party, and that domain returns a dead store on every path we tested. The live store operates under a different name again, and no legal entity, postal address or telephone number appears anywhere on it. Still circulating: A brand with a stated official website and a three-year manufacturer warranty. Contact runs through three email addresses and nothing else. Knowing who you would be claiming against, and where, matters more than the length of the term.MYNTA M1612 · The model designation · verified August 20, 2026Current primary value: Unresolved between M1612 and MC1612. The brand’s own video channel published a chair under MC1612, while listings and the affiliate site use M1612. Still circulating: Three strings circulating for what appears to be one chair, with at least four listings carrying the name against materially different feature copy. We publish M1612 because that is the retail designation, and we flag that the generation question is open. Where a spec came from a listing under one string, it may not describe the chair sold under another.
MYNTA MC4100 · Maximum user weight · verified August 20, 2026Current primary value: 200 lb, and it is the only fit figure published for this chair anywhere. No user height range exists at all. Still circulating: Nothing competing, which is the problem. Flagship listings in this bracket usually publish 260 to 300 lb, and a buyer scanning a feature list would not expect to find this one 60 to 100 lb lower. Check yourself against 200 lb before reading another line of the specification. At this price that ceiling is a genuine disqualifier for a large share of buyers, and it is the least advertised number on the chair.MYNTA MC4100 · Whether the back mechanism is 4D or 3D · verified August 20, 2026Current primary value: Unresolved. One listing for the identical stock code describes a 3D and 2D dual mechanism while another describes 4D and 2D, and both are selling the same chair. Still circulating: A flat 4D claim, which is how the chair is titled and how the channel describes it. What is not in dispute is the dual layout: a back unit and a separate glute and thigh unit working at once, which is genuinely unusual at this money. The depth rating on the back unit is not settled and we do not publish one.MYNTA MC4100 · What the manufacturer publishes · verified August 20, 2026Current primary value: Nothing publicly reachable. Seven candidate brand domains were probed. One is an affiliate site, one is parked and for sale, one is brand-controlled and returns a dead store on every path, and none serves a product page, spec sheet, manual or warranty document for this chair. Still circulating: A comparison table of MC4100 specifications, published by the site that titles itself the brand’s official website. Every published MC4100 specification traces to retail listings or to that one affiliate page. Wall clearance, track construction, heat zones and program lists are all unpublished by the manufacturer.MYNTA MC4100 · What the three-year warranty covers · verified August 20, 2026Current primary value: One year of parts, labour, in-home service and shipping, then parts only through year three, with lifetime email technical support, inside the 48 contiguous states. Still circulating: A flat three years of limited coverage, as the brand’s own store puts it, and a one-year warranty as one third-party reviewer reports it. Year one is the only complete year. The instrument also excludes buyers who did not purchase from the brand’s own store, so where you buy decides whether any of it applies.MYNTA MC4100 · Who is covered, and where · verified August 20, 2026Current primary value: The original purchaser from the brand’s own store, in the 48 contiguous states, for as long as they own the chair. Still circulating: A manufacturer warranty implied by every listing that sells the chair through another channel. Coverage does not transfer and does not renew, so a secondhand chair carries nothing and a replacement inherits only the remaining term. Commercial use voids it outright, with no light-commercial tier offered.MYNTA MC4100 · Chair weight · verified August 20, 2026Current primary value: Listed at 205 lb against dimensions of 62.6 by 30 by 45 inches. Still circulating: A physically smaller sibling listed at 209 lb, four pounds heavier on a smaller frame with one fewer mechanism. One of the two figures is likely wrong and no maker document exists to settle it. If a delivery route or a floor loading depends on the number, get it confirmed before ordering.
Osaki OS-4D Pro Maestro LE · Wall clearance behind the chair · verified August 20, 2026Current primary value: 4.7 inches, per the installation-position figure in both generations' manuals. Still circulating: 5 inches in Osaki's marketing block, and 3 inches in our own earlier review. The manuals govern. We corrected our own 3-inch figure everywhere it appeared, and anyone planning a room should budget the manual's 4.7 inches behind the chair plus roughly 25 inches of forward slide.Osaki OS-4D Pro Maestro LE · Airbag count · verified August 20, 2026Current primary value: 20, itemised in both manuals as 2 shoulder plus 12 arm, seat and waist plus 6 leg and foot. Still circulating: 32, in Osaki's marketing block and across much of the dealer channel. We publish 20 and name where the 32 came from. This is the cleanest checkable correction on the page: anyone can count the diagram in Osaki's own manual.Osaki OS-4D Pro Maestro LE · Track type · verified August 20, 2026Current primary value: Osaki's own manuals call the guide "L Shape 52.8"" for both generations, and its Shopify record tags the original LE L-TRACK. Still circulating: A 53-inch SL-track, marketed by Osaki's own retail pages and by nearly every dealer, including in our earlier review. We report both and let the manual lead, because an L-shaped rail and an S-plus-L rail describe different contact through the upper back. Buyers who care about spinal contour should not assume the S half exists on the strength of the marketing label.Osaki OS-4D Pro Maestro LE · Where the user height range is published · verified August 20, 2026Current primary value: 4 feet 9 inches to 6 feet 4 inches, with a 260 lb maximum, printed in the Q and A section of both generations' manuals. Still circulating: Dealer ranges that disagree with each other and with Osaki, and our own earlier claim that Osaki published no height figure at all. We got this wrong and are correcting our own correction. We previously published that Osaki states no height range anywhere; it does, in the manual's Q and A, and the 6 foot 4 ceiling we had carried before was Osaki's own figure all along. Plan against 4 foot 9 to 6 foot 4 and 260 lb, and know the number is buried where almost nobody looks.Osaki OS-4D Pro Maestro LE · Which chair the manual describes · verified August 20, 2026Current primary value: The original OS-4D Pro Maestro LE's own manual carries the model name "Osaki Pro Maestro 2.0" on its cover and in its specification table. Still circulating: The retail "Osaki 4D Maestro LE 2.0", a different and later chair entirely. Any writer trusting the manual's model field will file the original chair under the wrong generation, and any owner downloading a manual from Osaki's original-LE page gets the wrong book. Verify generation from the 4D level count and the voice-control feature, not from the name on the cover.Osaki OS-4D Pro Maestro LE · Warranty labour term · verified August 20, 2026Current primary value: One year of labour and two years of parts under the maker's standard plan bullets; three years of labour and five of parts under the extended plan Osaki bundles free. Still circulating: A headline 3 Year Standard Manufacturer's Parts and Labor Warranty on the same page. What Osaki actually sells today is the bundled five-year configuration, so most buyers get the better number. The headline on the standard plan still overstates its own bullets, and the structural-framework term stays at three years no matter which plan you hold.Osaki OS-4D Pro Maestro LE · In-home service · verified August 20, 2026Current primary value: Not provided in the maker's warranty text. The only documented mechanism is ship-in under a return authorization. Still circulating: In-home labour, promised by major dealers restating this warranty. On a chair of this weight the difference between a technician arriving and the owner crating it for freight is the whole cost of a repair. Get any in-home promise from the selling dealer in writing, because the maker's document does not contain one.Osaki OS-4D Pro Maestro LE · 4D depth levels · verified August 20, 2026Current primary value: Original LE: 8 forward-distance levels over approximately 3.9 inches. LE 2.0: 7 levels over approximately 4.96 inches. Still circulating: One dealer advertising 8 depth settings on the LE 2.0, which is the original's figure. The 2.0 reaches deeper with coarser steps; the original steps finer but does not travel as far. Neither is simply the upgrade, which is worth knowing before paying a premium for either.
Osaki OS-Champ · Maximum user weight · verified August 20, 2026Current primary value: 220 lb. The shipped manual states it twice: the Chair Specifications table on page 18 reads "Maximum body weight of user | 220 lbs", and the Caution box on page 3 reads "The user’s weight is usually limited to 220 lbs. For those who are weighing 220 lbs or more, the product operations may make more noise and the fabric cover may wear out faster.". Still circulating: 260 lb, published as "User Maximum Weight 260 lb" on the maker’s own spec table, and repeated by SelectFitness, Purely Relaxation, Recovery For Athletes and Consumer Files. We publish 220 lb as the number to buy on, because it is the figure in the document that ships in the box and the one the warranty’s operating instructions point at: coverage is void for failure to follow operating instructions. The manual’s own wording is softer than a hard cap, and the consequence it names is noise and faster fabric wear rather than structural failure. Anyone between 220 and 260 lb is told by the storefront that they fit and by the shipped manual that they are past the limit, and only Osaki can settle which figure governs a claim.Osaki OS-Champ · Chair width and doorway clearance · verified August 20, 2026Current primary value: 29.5 inches wide, per the manual’s specification table, which gives upright dimensions of 57.1 by 29.5 by 44.1 inches. Still circulating: 30.5 inches wide on the maker’s spec table, which publishes a minimum door width of 30.5 inches on the same screen. Treat the doorway figure as having no margin. If the manual is right, the published 30.5-inch minimum is an inch conservative and you are fine. If the spec table is right, a 30.5-inch doorway is a zero-clearance fit for a chair that ships fully assembled. Measure your narrowest doorway before ordering and add margin either way.Osaki OS-Champ · Massage styles and auto programs · verified August 20, 2026Current primary value: Five auto programs, named Relax, Stretch, Upper Back, Low Back and Demo, and six manual techniques. The manual’s own description of the Manual button lists kneading, Swedish, tapping, shiatsu, clapping and rolling. Still circulating: Five different massage styles, printed both on the storefront bullet and in the manual’s own Auto Programs blurb. Six techniques is the defensible number, because it comes from the manual enumerating actual button behaviour rather than from a marketing count. The auto-program count of five is not in dispute.Osaki OS-Champ · Auto body scan · verified August 20, 2026Current primary value: There is none. The controller map in the manual enumerates all 26 buttons and no scan is among them, and the word scan does not occur once in the maker’s spec and description file. Still circulating: Our own earlier review of this chair listed an auto body scan twice, once in the spec table and once as a reason to buy it. We were wrong and have removed it. You position the rollers yourself with the up and down buttons before a session. That is the normal arrangement at this price and it is not a mark against the chair, but publishing a feature it does not have was.Osaki OS-Champ · Track type, SL or L · verified August 20, 2026Current primary value: The maker calls it both. Its feature block prints SL-Track while its own body copy on the same file reads that the OS-Champ is an L-Track rolling system, and the banner image the file loads is named Osaki Champ L-Track. Still circulating: Six independent dealers publish L-Track and the maker’s own dealer-authored review publishes SL-track, which reads as a dealer-versus-dealer split until you notice both labels are the maker’s. Ignore the label and use the behaviour, which both descriptions agree on: the rollers run from the neck through the lower back to the glutes and upper hamstrings. That coverage is what separates this class from an older S-track recliner, and it is what you are buying.Osaki OS-Champ · Track length, roller count and user height · verified August 20, 2026Current primary value: Osaki publishes none of the three. No track length in inches, no roller count, no roller diameter and no user height range appears on the maker’s spec file or on any of the 21 pages of the shipped manual. Still circulating: Our own earlier review published a 49-inch L-track, quad rollers and a fit window of five feet even to six feet. Dealers are split three ways on height: one publishes 5′0″ to 6′0″, one says up to about 6′2″, and one says the chair does not suit anyone over 5′6″. We have withdrawn the numbers we could not source. The only fit constraints Osaki publishes are a user weight, which it states two ways, and an 18.0-inch shoulder width with a 20.5-inch seat. A height range would have to come from Osaki in writing or from a measured fit test, and importing one from a dealer listing is how a made-up number gets into circulation.Osaki OS-Champ · Wall clearance · verified August 20, 2026Current primary value: Not published. The maker states the chair slides forward up to 9 inches as it reclines, which is a travel figure, not a required gap behind it. Its Preparation before Use section asks only that you check the space around the product, with no number and no diagram dimension. Still circulating: Our own earlier review printed about 9 inches from the wall as a clearance spec, converting the maker’s travel figure into a room-planning number it never was. Nine inches of forward travel means the chair needs at least that much room in front of it to recline, and it tells you nothing about how close the back can sit to a wall. Measure with the chair fully reclined before you commit to a spot.Osaki OS-Champ · What the third warranty year covers · verified August 20, 2026Current primary value: Structural framework only, and only on selected products, which the maker never names. Year one is parts and labour, year two is parts. Still circulating: Our own earlier review said parts only in years two and three. One dealer headlines the same three years as covering all parts, labour and framework throughout, and another restates it as one year of in-home labour with extended tiers adding more. Buy expecting parts and labour for one year and parts for one more. Treat the third year as unresolved until Osaki publishes the list of selected products, and treat in-home service as not offered: the instrument routes every claim through a return authorization and a shipment to a service center.Osaki OS-Champ · How long a session can run · verified August 20, 2026Current primary value: Fifteen minutes by default, adjustable from five to thirty on the timer, per the manual’s specification table and its controller pages. Still circulating: The manual’s safety page caps use at thirty minutes at a time; its troubleshooting page describes a forty-five-minute continuous-use overheat trip needing a sixty-minute cool-down; and the marketing copy says all five auto programs run fifteen minutes each while naming Demo, one of those five, as a five-minute program. Plan around thirty minutes as the stated ceiling and treat the forty-five-minute trip as a protection circuit rather than a permission. The marketing paragraph is simply wrong about its own Demo program.
Real Relax MM350 · Who pays shipping on a warranty repair · verified August 20, 2026Current primary value: Unresolved by the maker. One instrument allocates shipping cost three mutually incompatible ways, two of them inside the same document, and the maker’s two official domains publish different versions of the same clause. Still circulating: A single answer, which is what a buyer reading any one page would take away. Get the shipping answer in writing before you need it. On a chair this size the freight can be a meaningful fraction of what you paid.Real Relax MM350 · What one year of coverage includes · verified August 20, 2026Current primary value: Materials only. There is no frame term, no upholstery term, no parts term and no labour term, because the instrument covers the chair as one undifferentiated unit and caps the maker’s obligation at the cost of materials. Still circulating: Three years on the frame, one on parts and no labour, published by an aggregator and repeated in search summaries. Read it as one year of parts, self-fitted. Real Relax states plainly that it does not send technicians, so the owner diagnoses and replaces using pictures and videos the company supplies.Real Relax MM350 · How long the manual says the warranty runs · verified August 20, 2026Current primary value: It never says. The manual that ships in the box references the original warranty period repeatedly and states no number anywhere in it. Still circulating: One year, badged on the product pages and stated in the FAQ and the return policy. One year is the number, and a buyer who only has the manual cannot learn it. Note also that the defect-notice window is 14 days from the fault occurring, with a photo or video, which is far shorter than the term itself.Real Relax MM350 · Fit range · verified August 20, 2026Current primary value: Two different height ranges on one page, one in the specification table and one in the FAQ below it. No maximum user weight is published anywhere. Still circulating: A single fit envelope, which is what a spec table implies. Treat the fit figures as unsettled and ask the seller. A missing weight capacity is the more serious of the two gaps, because it is the specification most likely to be argued about in a claim.Real Relax MM350 · Whether it has automatic programs · verified August 20, 2026Current primary value: Unresolved across three maker statements, which disagree about whether the chair has preset programs at all. Still circulating: Six preset programs, claimed in the product page feature block. What is documented is the mechanism: eight fixed massage points across two independent roller assemblies, one for the neck and back and one for the waist. This is a two-dimensional chair with no track in the S or L sense, and the maker files it that way.Real Relax MM350 · Rated power · verified August 20, 2026Current primary value: Disputed between the maker’s own web table, which says 90 W, and the manual’s specification page, which says otherwise. Still circulating: The web figure, repeated in the FAQ on the same site. Small in practice and useful as a signal. The web pages and the in-box document are maintained separately and have drifted, which is the same pattern behind the shipping clause and the carton count.
Real Relax PS6500 · Maximum session time · verified August 20, 2026Current primary value: Fifteen minutes, per the rated time in the manual’s specification table, which is the primary document. Still circulating: Two other figures from the same maker: a longer cap in the manual’s own safety precautions, and a longer one again elsewhere in its documentation. This is the one contradiction here with a plausible path to harm, because a buyer reading the longest figure could run the chair well past the rated time. Treat 15 minutes as the design figure and the longer numbers as protection circuits rather than permissions.Real Relax PS6500 · Maximum user weight · verified August 20, 2026Current primary value: 220 lb, published in the product page specification table alongside a height range, and absent from the manual’s specification table entirely. Still circulating: Nothing competing, and that is the issue: the most consequential number on the chair exists only in marketing. Two hundred and twenty pounds is low for this price class. Confirm it with the seller in writing, because a capacity that lives only on a web page is the easiest kind of specification to change without notice.Real Relax PS6500 · How many massage techniques it has · verified August 20, 2026Current primary value: Unresolved. The product page states the technique count two incompatible ways within a single page. Still circulating: The higher of the two figures, which is the one the feature highlights lead with. The auto-program count, by contrast, checks out exactly: 27 programs across five parent groups, enumerated in the manual and matching the claim. That is a rare positive and worth saying.Real Relax PS6500 · Wall clearance · verified August 20, 2026Current primary value: Ten centimetres behind, per the product page FAQ, with the manual’s placement diagram carrying the fuller picture. Still circulating: The rear figure alone, which is all the FAQ publishes and all most listings repeat. Rear clearance is not the whole answer on a chair that slides forward as it reclines. Measure the space in front as well before you commit to a spot.Real Relax PS6500 · What certification the maker claims · verified August 20, 2026Current primary value: A radio-module statement only, printed in the manual immediately below the specification table, with a matching pair of identifiers that the product page repeats. Still circulating: A certification mark, which is how a compliance statement in a manual reads at a glance. Report it as a radio-module compliance statement, never as a safety certification. The identifiers do lock the model identity, since the manual and the listing carry the same pair.Real Relax PS6500 · Who pays freight on a warranty part · verified August 20, 2026Current primary value: Half, for the entire one-year term, per the clause that splits replacement-part freight with the owner. Still circulating: The full cost, per a line a few paragraphs earlier on the same page, and a differently conditioned version of the clause on the maker’s second official domain. Assume you are paying something and get the figure in writing. On a 205 lb chair the freight is not a rounding error.
Titan Pro Commander · Auto-program count · verified August 20, 2026Current primary value: Six, shown on the AUTO tab screen capture in Titan's own instruction manual. Still circulating: Five on Titan's own storefront bullet and most dealers, seven on one stale dealer page, and five in our earlier review. The manual is the primary document and shows six. We publish six and name the conflict, because a buyer counting programs against the storefront bullet will find one more than advertised.Titan Pro Commander · Warranty structure · verified August 20, 2026Current primary value: Year one parts and labour, year two parts only, and a three-year structural framework term granted only 'on selected products'. Still circulating: Three years of parts with one year of labour, as our earlier review and much of the channel state it. Titan never publishes which products are 'selected', so the three-year frame term is not confirmable for this chair. Get it in writing from the seller.Titan Pro Commander · In-home service · verified August 20, 2026Current primary value: Not provided. The maker's text describes one route and it is ship-in under a return authorization. Still circulating: In-home labour, promised by at least one dealer in its own product-specific warranty tab. On a chair of this weight the difference between a technician arriving and you crating it for freight is most of the cost of a repair. Confirm any in-home promise with the dealer in writing.Titan Pro Commander · Published fit range · verified August 20, 2026Current primary value: Titan publishes none. No user height range and no user weight capacity appears on its product page, in its spec fragment circulated to dealers, or in the 18-page instruction manual, whose specification table carries five rows and no body-size section. Still circulating: A 240 lb capacity with a 6 foot 3 inch height ceiling, repeated across the channel and, until this correction, on five of our own pages. We were wrong to publish it and have removed it. The only user-eligibility statement Titan makes is a warning that under-18s and people with disabilities should not operate the chair without a doctor’s consent. If fit is your constraint, this chair cannot answer it and no amount of dealer copy changes that.
Real Relax Favor-03 · Weight capacity · verified August 19, 2026Current primary value: 240 lb, the official figure on the current 2026 3D Lite page. Still circulating: 400 lb and 440 lb claims from the fixed-roller era. Shop against 240 pounds. The old numbers describe hardware Real Relax no longer sells new.Real Relax Favor-03 · Roller hardware · verified August 19, 2026Current primary value: SL track with a moving roller carriage and shoulder detection. Still circulating: 8 fixed rollers with no track (PLUS era) or a dual-core S-track (ADV era), as described in older reviews that still rank in search. Any review describing fixed massage nodes is about a chair you can no longer buy new.
