Massage, then stretch
Deep 4D work, then a slow tilt past flat.
Settle into the reading corner with your phone in hand. Choose a program in the app, let the scan find your shoulders, then feel the chair tilt back past level for a stretch you cannot get sitting upright.
- Scan TrueFit first Scanning maps shoulder position and body length before the session.
- Work 4D depth and speed Four-node rollers change depth and speed as well as position.
- Stretch True inversion Extension and waist-twist programs use the chair's full inversion range.
What the hardware feels like
-
Massage with range
Kneading, tapping, knocking, shiatsu and synchronized motions, with adjustable depth.
4-node 4D mechanism, 9 programs
-
The stretch
The chair reclines near flat and into true inversion for its stretch programs.
Near-flat S-Track, true inversion
-
Your phone is the remote
Run sessions from the app or the color remote, with music synced to the massage rhythm.
iOS and Android app, Rhythm Sync
The honest math
$6 a session
$7,999, used 5 times a week for 5 years (the length of its structural warranty), works out to about $6 per session. Your own rhythm sets the real number.
Why we carry it
We carry the X3 for people who want more than massage. Inversion and stretch programs make it a different kind of session, and Infinity backs it with a five-year structural warranty and unlimited USA-based support. If you will not use the stretch, compare the Hatsumei M900 first.
4D massage | True inversion
Deep 4D work, then a near-flat reset.

More range, without more friction.
The X3 changes depth and speed as well as position, giving the four-node mechanism more ways to shape a session. TrueFit scanning maps the user first, then the chair can move through focused techniques, stretch programs, near-flat recline, foot rollers, and lumbar heat from the remote or phone.

Common questions
How does delivery work?
Infinity and Kyota massage chairs have an expected delivery time of 2 to 4 weeks, including handling and transit, subject to supplier availability and delivery scheduling. Eligible lower-48 curbside freight is included. Indoor placement and optional upgrades are separate. Questions about stairs or tight access? Chat or email us before you order.
Can I pay over time?
Eligible orders may show Shop Pay Installments through Affirm at checkout. Rates, terms, and approval depend on the provider and your application.
What is covered by warranty?
5-year residential limited warranty: 1 year complete care (parts and labor), 3 years parts, 5 years structural. Unlimited USA-based support.
If something goes wrong, we help coordinate the claim with the brand's support team so you do not have to chase it alone.
Can I return it?
Start a return at support@solisrestore.com. Unused items in original packaging may be returned within 30 days of delivery. A 25% restocking fee applies to those returns; it is never charged when the item arrived damaged, defective, or incorrect. Customer pays return freight unless the item arrived damaged, defective, or incorrect. A cold plunge that has been filled is not a standard unused return. Certified pre-owned chairs are not eligible for a standard 30-day return; CPO returns are limited to damage, defect, or incorrect item on arrival. Custom or made-to-order products are not returnable. Review the current return terms.
What if I am not sure this is the right product?
Use the fit check below. Tell us about your space, goals, and budget, and we will help you understand which category or product makes the most sense.
Will it fit through my door and into the room?
Most issues are doorway width, stair turns, and ceiling height, not the spec sheet. Send your dimensions through the fit check and we confirm the delivery path before you order.
What does it need from the room?
Cold plunges need a level surface, an outlet, and a plan for filling and draining. Massage chairs need floor space and a standard outlet. Red light panels need a mounting spot or stand within reach of the routine.
How many boxes arrive, and who brings them in?
Smaller systems ship parcel to your door. Larger systems ship freight, usually curbside unless the brand offers an upgraded service. We confirm the exact arrangement for your product after order.
Questions? We are here to help.
Email us or use chat for product, setup or order questions.
From the founder
I want to make it easier to give yourself some of the attention you give everything else. It starts with finding equipment that feels at home in your space, and a routine that feels like time well spent.
