The cheapest seat in a Kokoro M888. Grade B chairs passed Kyota's 37-point inspection in perfect working order and carry minor cosmetic flaws that change nothing about the massage. Same 4D mechanism, same warranty backing, lower price than Grade A.
What Grade B means
- Passed Kyota's 37-point factory inspection
- Perfect working order
- Minor cosmetic flaws that do not affect operation, priced below Grade A
The chair itself
Kyota's 4D mechanism with adjustable width, length, and depth rides a J-track, which pairs full-spine coverage with glute reach and keeps the decompression stretch effective. You get tri-zone heat therapy, calf-kneading rollers, shoulder airbags, body scanning, an air ionizer, Bluetooth speakers, USB charging, and a zero-wall, zero-gravity recline.

Customer reviews
New to massage chairs? The jargon, translated
Every spec on this page, in plain English. Massage chairs are a big purchase, and the industry buries the important stuff under acronyms. Tap any term.
2D, 3D, 4D — what the numbers mean
The number tells you how the rollers move. 2D rollers travel up-down and side-to-side at one fixed depth. 3D adds depth: the rollers push into your back harder or softer, so you choose how deep the massage goes. 4D adds changing speed mid-stroke, which is what makes it feel like human hands instead of a machine on a loop. If you want real deep-tissue work, treat 3D as the minimum; 4D feels the most human and costs the most.
S-track, L-track, SL, J-track
The track is the rail the rollers ride along your body. An S-track follows the curve of your spine from neck to lower back and is best for stretch programs. An L-track keeps going under the seat, so the rollers also massage your glutes and hamstrings. SL and J tracks combine both ideas. Longer track means more of you gets massaged; S-track chairs usually stretch you harder. The number before it (like 49") is the track's length.
Zero gravity recline
The chair reclines until your knees sit slightly above your heart, the posture NASA designed for astronauts at launch. Your weight spreads evenly across the chair, pressure comes off your spine, and the rollers press deeper without you tensing up. Most chairs offer two or three zero-gravity stages.
Zero wall / space-saving
A zero-wall chair slides forward as it reclines instead of tipping backward, so it can sit a few inches from your wall instead of two feet. The spec to check is the clearance number: 2" to 6" on the chairs we carry. If your room is tight, this matters more than almost any massage feature.
Airbag compression
Air cushions built into the arms, shoulders, hips, calves, and footrest inflate and squeeze, like a blood-pressure cuff. The rollers handle your back; the airbags handle everything the rollers can't reach. More airbags with independent zone control means the squeeze lands where you want it and skips where you don't.
Body scanning
Before the massage starts, the chair maps your height, shoulder position, and back curve, then adjusts the rollers to your body instead of an average person's. This is why two people can use the same chair and both get a massage that lands in the right spots.
Reflexology foot rollers
Spinning textured rollers under your soles that press the pressure points a foot massage therapist would work with thumbs. Paired with the footrest airbags squeezing the top of your feet, it is the feature people don't know they want until the first session. "Triple rollers" means three rollers per foot instead of one.
Heat therapy
Heating pads, usually at the lower back, warm the muscle before and during the massage so it loosens and deep pressure doesn't ache. Better chairs add heat zones at the calves or feet, or put the heat in the rollers themselves so warmth travels with the stroke.
Dual mechanism (Syner-D)
Most chairs have one roller unit that travels your whole back. A dual-mechanism chair has two separate units working at the same time: one on your neck and upper back, another on your lower back and glutes. It feels like two therapists working on you at once, and it is the main thing you pay for in flagship chairs like the Kyota Nokori and Infinity Luminary.
Certified Pre-Owned: Grade A vs Grade B
Every CPO chair passes the factory's 37-point inspection by factory-trained technicians before it ships. Grade A: perfect working order, no major cosmetic flaws; many are showroom units or returns that were barely used. Grade B: works exactly the same, but carries a visible scuff or scratch, and is priced lower for it. Both are the same chair inside. Ask us for photos of the exact unit before you buy.
Common questions before you buy
Delivery, returns, and the practical stuff.
What are my delivery options, and what do they cost?
Three tiers, and you pick at checkout. Free curbside (included): the freight carrier brings the chair to your driveway or entryway in its factory boxes; you bring it inside. Threshold, $99: the carrier places it just inside your doorway. White glove, $199: a two-person team carries it to the room you choose (stairs included), unpacks it, assembles it, and removes the packaging. If nobody strong is around to help, white glove is worth it; chairs weigh 200+ lbs boxed.
How long does delivery take?
Curbside and threshold average 7-10 business days from order. White glove runs 10-14 business days because the chair routes through an installation terminal first, and the team calls you to schedule a window. Tracking is emailed within 24 hours of your chair leaving the warehouse.
Is assembly hard?
No special tools or skills. Assembly is attaching the arms, ottoman, and air hoses with the included instructions, and takes 30-90 minutes. If you'd rather not, white glove delivery includes full assembly. And if you get stuck, call us at 806-547-1998 and we'll walk you through it.
What if I don't like the chair?
You have a 60-day money-back guarantee from the purchase date, with no restocking fees. You pay only return shipping, capped at the lesser of the actual freight cost or a $250 flat fee. Full details on our Shipping & Returns page.
Is the warranty included?
Yes. Every new chair carries its full manufacturer warranty, and Certified Pre-Owned chairs are backed by warranty as well — we're an authorized dealer, so coverage is the real thing, registered to you.
Can I pay monthly?
Yes — Affirm and Shop Pay Installments, with 0% APR for qualified buyers and terms up to 36 months. Checking your rate takes about a minute and doesn't affect your credit score. See real monthly examples on our Financing page.
