Quick answer: Buy Luraco’s i9 Max Plus (about $13,490) if Made-in-USA assembly and FDA/UL/CE medical-device certification are non-negotiable — it’s one of the only flagship-tier chairs in this category you can actually order with confidence. Buy Kahuna’s DIOS-6800 (about $3,799) if price-per-feature matters more than pedigree — just confirm it’s still in stock first, because most of Kahuna’s catalog currently isn’t.
Kahuna and Luraco sit at nearly opposite ends of this site’s brand map. Kahuna built its following on one idea: beat Japanese-style flagships on price, even if that means steep “sale” pricing against inflated MSRPs. Luraco built its following on the opposite idea: charge a real premium for something no other brand in the category offers — chairs assembled in Arlington, Texas, carrying FDA, UL and CE medical-device listings. This comparison isn’t really about which chair massages better. It’s about whether you’re buying on price or on pedigree, and — for Kahuna specifically — whether the chair you want is even something you can order today.
By the numbers:
- Kahuna showed only 3 in-stock SKUs out of roughly 30 model-and-color listings on kahunachair.com in July 2026 — every LM, SM, EM and HM series chair was marked sold out (per our Kahuna lineup check).
- Luraco states it is the only massage chair brand still assembling in the USA (Arlington, Texas), and unlike Cozzia and Daiwa’s dealer-only flagships, all four current Luraco models are listed on Amazon.
- The i9 Max Plus prices at roughly $13,490 — about 3.5x Kahuna’s in-stock flagship, the DIOS-6800 at $3,799.
- Luraco’s warranty runs 5 years on parts, 3 years of in-home service and 10 years on leather, versus Kahuna’s legacy-chair terms of 3 years structure, 2 years parts and just 1 year of parts-and-labor.
- Roughly 24% of US adults report chronic back pain (CDC data) — the buyer segment most likely to weigh Luraco’s medical-grade certification against a cheaper, harder-to-source chair from Kahuna.

Entry tier: CM-Hani vs Sofy
Kahuna CM-Hani
- Kahuna's cheapest current chair and one of only three SKUs the brand showed as actually orderable in July 2026.
- Compact recliner footprint built for smaller frames and smaller rooms, not a scaled-down flagship.
- No medical-device listing — a straightforward consumer recliner with massage and heat functions.
Luraco Sofy
- Positioned as a theater/recliner-style seat with massage and calf-roller functions — not a UL/FDA/CE-listed medical chair like the i7 Plus and i9-series.
- Still assembled in Arlington, Texas, so you get Luraco's build quality without the medical-chair price floor.
- Nearly double the CM-Hani's price for a chair that, like the CM-Hani, isn't medical-grade — the Sofy's case is build origin, not certification.
Verdict: Kahuna’s CM-Hani is the easier entry-tier buy on pure price, and — unlike most of the brand’s catalog — it’s actually in stock. The Sofy only makes sense here if Luraco’s domestic assembly matters to you at this budget; neither chair carries the medical-device listing that defines Luraco’s higher tiers.
Flagship: DIOS-6800 vs i9 Max Plus
Kahuna’s DIOS-6800 runs a “6D” dual-core mechanism — two 3D roller carriages working in tandem on a 50-inch SL-track — a genuinely novel engineering approach, not a cut-rate copy of a 4D chair. At $3,799 it undercuts Luraco’s i9 Max Plus by roughly $9,700. The i9 Max Plus answers with a patented Split L-Track, 3D Butterfly Technology rollers, adjustable-position armrests, and — the part no Kahuna chair offers — UL, FDA and CE medical-device listing, backed by Luraco’s 5-year parts / 3-year service / 10-year leather warranty.
The honest read: this isn’t really a close fight on mechanism-for-dollar. The DIOS-6800 is the better value by a wide margin if all you want is a strong massage chair. The i9 Max Plus’s case rests entirely on things the DIOS-6800 cannot offer at any price — domestic manufacturing and a certification that puts the chair in commercial/clinical settings as well as home use. And the DIOS-6800 comes with a caveat the i9 Max Plus doesn’t: it was one of only three Kahuna chairs we found in stock in July 2026, while all four Luraco models remain listed and orderable on Amazon. Our standalone DIOS-6800 review covers that stock-signal problem in more depth, along with a track-length contradiction found on one retailer’s own listing.
Availability: the real deciding factor
This is where the comparison stops being about specs. Kahuna is winding down its older LM, SM, EM and HM series inventory while shifting production to the DIOS line — in July 2026, roughly 27 of 30 model-and-color listings on kahunachair.com were sold out, and a large authorized dealer, Massage Chair Heaven, showed all 14 of its Kahuna listings sold out on the same day. Buying most of the Kahuna catalog today means buying remaining retailer stock of a chair the brand may no longer support with parts.
Luraco has no equivalent problem. All four current models — Sofy, i7 Plus, i9 Max Plus and i9 Max Plus SE — are listed under Luraco’s own Amazon storefront, including the $14,990 flagship. That’s unusual for this price tier: Cozzia and Daiwa’s flagships are dealer-only with no Amazon listing at all, and Kahuna’s own flagship-adjacent models are frequently out of stock everywhere. If “can I actually buy this” is part of your decision, Luraco wins outright.
Warranty and service
- Coverage: Luraco publishes 5 years on parts, 3 years of in-home service and 10 years on leather. Kahuna’s legacy-chair terms are 3 years structure, 2 years parts and 1 year of parts-and-labor.
- Service network: Luraco answers its own warranty claims rather than routing through an overseas OEM. Kahuna’s shrinking active catalog makes long-term parts availability a live concern, especially on discontinued LM/SM/EM/HM chairs.
- Buying a Kahuna chair outside the DIOS-6800, CM-Hani or CM-Hani3200 in 2026 generally means buying legacy stock — confirm any warranty claim in writing from the specific seller before ordering.
The bottom line
If domestic assembly and FDA/UL/CE medical-device certification are real requirements, buy the Luraco i9 Max Plus — it costs roughly 3.5x the DIOS-6800, and that premium buys things no Kahuna chair offers at any price. If you want the most massage mechanism per dollar and you’ve confirmed it’s still orderable, the Kahuna DIOS-6800 is a genuinely strong chair at under a third of the cost. Either way, check stock before you commit to a Kahuna model — our full Kahuna lineup ranking and Luraco lineup ranking walk both brands tier by tier, and our Kahuna vs Osaki and Luraco vs Osaki comparisons show how each stacks up against the category’s volume leader.
