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.
Kahuna Chair 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 Chair 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 Chair 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 Chair 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, and we put the question to Luraco. 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. The question is with Luraco.
Real Relax Favor-03 (2026 3D Lite) · 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 (2026 3D Lite) · 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.
