House of Massage Chairs · Model Guide
The Infinity Gen Max 4D massage chair is a control-first 4D chair with a 49-inch L-track, TrueFit body scanning, active calf kneading and oscillation, triple foot rollers, and a two-inch wall clearance — built for buyers who want serious lower-body attention without moving into a larger dual-mechanism chair.
01 · In One Minute
A long massage path. A serious lower-body finish.
In brief
The Infinity Gen Max 4D massage chair is a premium 4D chair for users 5 ft 4 in to 6 ft 9 in and up to 300 lb. Its core combination is a 49-inch L-track, TrueFit body scanning, adjustable 4D speed and depth, active calf kneading and oscillation, and three sole rollers per foot. Twelve automatic programs simplify daily use, while the remote and iOS/Android app allow adjustment. The tradeoff is scale: the chair weighs 324 lb and reaches 80 inches long reclined. Zero Wall Fit cuts rear clearance to two inches, but the room and delivery route still must fit the chair.
4D mechanism
The back-and-glutes mechanism varies speed and depth, giving you more control over pressure character.
49-inch L-track
The published track carries massage from the back toward the glute area.
TrueFit alignment
Body scanning sets a better starting position; TrueFit footrest extension adjusts for leg length.
Active lower body
Calf kneading and oscillation pair with three sole rollers per foot.
12 auto programs
Twelve automatic sessions reduce setup time; the remote and app handle adjustments.
Room-aware recline
Zero Wall Fit requires two inches behind a chair that reaches 80 inches reclined.

The Mechanism
Depth and speed are part of the massage, not fixed settings.
The Gen Max uses a 4D back-and-glutes mechanism that moves vertically, laterally, and in and out for intensity while also varying speed. The result is more control over massage character than a fixed-depth, fixed-pace system.
- Mechanism4D back and glutes
- TechniquesKneading · tapping · knocking · shiatsu · sync · 4D shiatsu
- Massage head360-degree 4-node plus system
Why it mattersVariable depth and speed make it easier to find a repeatable pressure preference.
The Fit Baseline
The scan starts the session. Your body still decides the fit.
TrueFit Body Scanning helps position the roller system for the user. A 49-inch L-track carries massage toward the glute area, while TrueFit footrest extension adjusts for leg length.
- Body scanTrueFit Body Scanning
- Track49-inch L-track
- FootrestTrueFit extension
Why it mattersScanning helps alignment; shoulder, seat, calf, and foot fit still need a personal check.
The Stretch & Recline
Extension, zero gravity, and rocking give the chair three different moods.
The Extension program coordinates recline and air support for a controlled stretch sensation. Weightless Zero Gravity changes the resting angle, while Metronome Rocking adds gentle repeated motion. These are comfort features, not medical treatment.
- StretchExtension program
- ReclineWeightless Zero Gravity
- MotionMetronome Rocking
Why it mattersDifferent programs give a quick reset and a longer session distinct physical character.
The Lower Body
Kneading calves. Three rollers under each foot.
Complete Calf Kneading + Oscillation adds active lower-leg movement. Three sole rollers per foot work underfoot, while air compression and TrueFit footrest extension support positioning.
- CalvesKneading + oscillation
- FeetThree sole rollers per foot
- AirCompression with adjustable shoulder airbags
Why it mattersTest calf and foot pressure conservatively; lower-body intensity is highly personal.
The Room Fit
Only two inches behind it. Still a full-size 324-pound chair.
Zero Wall Fit moves the chair forward while reclining, reducing rear clearance to two inches. The chair itself remains 35 inches wide, 66 inches long upright, and 80 inches long reclined.
- Wall clearance2 inches
- Width35 inches
- Length66 upright · 80 reclined
- Chair weight324 lb
Why it mattersDoorways, turns, stairs, and the reclined footprint still decide delivery fit.
03 · The Session Character
A program should feel different, not merely have a different name.
The Gen Max is most convincing when the controls change the session. TrueFit scanning sets the starting position; 4D depth and speed shape pressure; the program library changes the sequence.
Around that core sit lumbar heat, soundscapes, Bluetooth speakers, rocking, and app control. They matter only if they make the chair easier to use regularly.

- v.Remote + mobile appChoose the control method you prefer
The Gen Max 4D is a comfort and relaxation product.
04 · Fit & Personalization
The published range is useful. The seated fit is decisive.
Infinity publishes an optimal height range of 5′4″–6′9″, a 300 lb maximum user weight, 17-inch seat depth, 20-inch hip width, and 23-inch shoulder width. Those numbers screen fit; the chair still has to meet your shoulders, calves, and feet correctly.
Compare this model in person →Start with the published 5′4″–6′9″ optimal range.
Measure comfort, not just clearance.
Published hip width is 20 inches and shoulder width 23 inches. Scanning cannot change seat geometry.
Let the lower-body system prove itself.
TrueFit footrest extension adjusts for leg length. Test calf kneading and the three sole rollers conservatively for pressure and placement.
Use the 4D controls before choosing a favorite program.
Depth, speed, air compression, and shoulder airbags change feel. Every regular user should test a repeatable setting.
05 · Feature Index

08 · The Decision
Who the Infinity Gen Max 4D massage chair fits — and who should keep comparing.
A strong fit if you…
- Want adjustable 4D depth and speed rather than a fixed massage character.
- Care about a long 49-inch L-track and want the massage path to continue toward the glute area.
- Put calf kneading, oscillation, and triple foot rollers high on the shortlist.
- Fall within the published 5′4″–6′9″ optimal height range and at or below the 300 lb maximum user weight.
- Need minimal rear wall clearance and can still accommodate a 35-inch-wide, 80-inch-long reclined footprint.
Consider another model if you…
- Have a regular user outside the published optimal height range and cannot verify shoulder, footrest, and calf fit before purchase.
- Need a chair below the 324 lb product weight or a shorter reclined footprint for delivery or room planning.
- Prefer very gentle calf and foot pressure and have not tested the lower-body system at its lowest comfortable setting.
- Want a physically smaller Infinity alternative with a published 59-inch upright and 74-inch reclined length.
Closest Alternative
The nearest in-brand alternative is smaller and lighter.
The Smart Chair X3 is the practical alternative when you still want 4D massage but need a smaller physical package or shorter published fit range.

Exact-Model Questions
What buyers need to verify before checkout.
Where can I buy the Infinity Gen Max 4D massage chair?+
At House of Massage Chairs, an authorized Infinity dealer. Order the Infinity Gen Max 4D online with free US shipping and white-glove delivery and setup, or buy it at our San Jose (Westfield Oakridge) or Pleasanton (Stoneridge) showroom, where walk-ins are welcome. Call or text (669) 214-8889 with questions before you order the Gen Max.
Can I try the Infinity Gen Max 4D before buying?+
Yes. The Infinity Gen Max 4D is on the floor in both our San Jose (Westfield Oakridge) and Pleasanton (Stoneridge) showrooms. Each is 3,500–4,000 sq ft and carries 70+ chairs, so you can compare everything in one visit without driving to another store, and walk-ins are welcome with no appointment needed. Test shoulder alignment, calf pressure, foot placement, 4D intensity, and the Extension program.
What are the dimensions and wall-clearance requirements for the Gen Max 4D?+
35 inches wide. The Infinity Gen Max 4D measures 66 inches long and 48 inches high upright, and 80 inches long and 36 inches high reclined. Zero Wall Fit needs only 2 inches behind the chair. At 324 lb, measure doors, halls, stairs, and turns before delivery, not just the room where the Gen Max will sit.
What height and weight range does the Infinity Gen Max 4D fit?+
5 ft 4 in to 6 ft 9 in, with a 300 lb maximum user weight. Infinity publishes that optimal range for the Infinity Gen Max 4D, with a 17-inch seat depth, 20-inch hip width, and 23-inch shoulder width. TrueFit footrest extension adjusts for leg length, but test shoulder, calf, and foot fit in person when possible.
What massage mechanism and track does the Infinity Gen Max 4D use?+
A 4D back-and-glutes mechanism on a 49-inch L-track. The Infinity Gen Max 4D varies roller speed and depth, uses a 360-degree 4-node massage head, and carries massage from the back toward the glute area. TrueFit Body Scanning helps set the starting position before each session.
Should I buy the Infinity Gen Max 4D or the Smart Chair X3?+
Choose the Infinity Gen Max 4D for a longer 49-inch L-track, Complete Calf kneading and oscillation, triple foot rollers, and a taller 5 ft 4 in to 6 ft 9 in fit window. Choose the Smart Chair X3 for a smaller, lighter chair with a near-flat S-track: 286 lb and 74 inches reclined, versus 324 lb and 80 inches on the Gen Max.
What is the difference between the Infinity Gen Max 4D and the Celebrity Elite 4D?+
Lower-body hardware and room size. The Infinity Gen Max 4D adds Complete Calf kneading and oscillation, triple foot rollers, a 49-inch L-track, and a 2-inch wall clearance. The Celebrity Elite 4D adds 24 automatic programs, foot heat, an 8-inch tablet, and voice control in a lighter 203 lb chair, versus 12 programs and 324 lb on the Gen Max.
Is the Infinity Gen Max 4D worth it?+
Yes, if lower-body hardware and a long track matter most: 4D speed and depth on a 49-inch L-track, Complete Calf kneading and oscillation, three sole rollers per foot, and Zero Wall Fit with 2 inches behind the chair. If you need a smaller or lighter chair than 324 lb and 80 inches reclined, the Smart Chair X3 may suit you better than the Infinity Gen Max 4D.
What warranty comes with the Infinity Gen Max 4D?+
5 years. The Infinity Gen Max 4D comes with Infinity's 5-year U.S. residential limited warranty, and House of Massage Chairs is an authorized Infinity dealer. Infinity lists 5 years on the structural frame, 3 years on covered parts, and 1 year of covered labor for this model, so ask us for the written coverage before you order. Your Gen Max purchase is also covered by our 6-Month Price Protection.
Is the Infinity Gen Max 4D HSA/FSA eligible?+
Yes. The Infinity Gen Max 4D is HSA/FSA eligible with a Letter of Medical Necessity (LMN). Our HSA/FSA massage chair guide explains how buying with HSA or FSA funds works, and you can call or text (669) 214-8889 with questions before you order the Gen Max.
Before You Decide
The fit questions belongin the chair.
The specifications narrow the shortlist. The final decision is physical: shoulder alignment, 4D pressure, calf kneading, foot-roller position, Extension, recline comfort, noise, and control simplicity.
Walk-ins are welcome, no appointment needed; the Gen Max 4D is on the floor in both showrooms, and each carries 70+ chairs. Call or text (669) 214-8889 with any questions before you visit.
The Decision
Infinity Gen Max 4D.
Choose the Infinity Gen Max 4D for adjustable 4D massage on a 49-inch L-track, active calf kneading and oscillation, three sole rollers per foot, and two-inch rear clearance. At 324 lb and 80 inches long reclined, the Gen Max still demands a body fit, room plan, and delivery route.

Amazing service from Gio! Totally no rush, no pressure to make a purchase! Gio was open, and took the time and initiative to make sure we were getting the chair that best fits our needs and pricing. We glad we made this purchase!
Y. G. · Pleasanton showroom · Google review
Henry and Shawn were absolutely amazing in helping us select the chair of my dreams. They went over and above in not only helping me compare the models and benefits but to also explain the technology behind the various ones I tried. Go here and be happy with the chair you pick!
M. R. · San Jose showroom · Google review
Just had an amazing experience buying my first massage chair. Gabe was very patient and explained in detail all the different chairs available in their showroom. They have a lot of different chairs in their showroom. I highly recommend coming here if you need to buy a massage chair!
S. L. · Pleasanton showroom · Google review
My husband and I stopped in on the fly to look at a foot massager. We got the best help from Shawn. He was so patient with us in our indecisiveness. Shawn is very knowledgeable in the inventory and we willingly tried a massage chair to check the new tech of the chairs. We tried several different chairs and ended up purchasing the 'Ferrari' chair. We are so grateful for his patience, his knowledge, and his continually helping us and with all the settings. We are excited about our new purchase and we are looking forward to the benefits and relaxing moments that await. Thank you Shawn for your help and good luck to you!

Great experience shopping for a massage chair here! The store has a wide selection of massage chairs that you can actually try, which really helped us compare the different options.
My husband and I spent about two hours trying different chairs, and Shawun was very patient and helpful throughout the entire process. He let us try all the chairs we were interested in and clearly explained the features and differences between each one. We finally found a chair that we both really liked.
We really appreciate Shawun help, as well as Michael’s assistance. Great selection and very helpful service. Highly recommended!
N. M. · Pleasanton showroom · Google review
My wife and I have been looking at Massage Chairs on line for quite some time. Everything I've read, said to go out and try several to see what is the best fit, comfort and price.
Today, we went to House of Massage Chairs and met with Henry Ipek. He showed us numerous massage chairs to find out what was the best fit for us. I think we probably tried 10 different chairs while we were in the store.
Finally, my wife and I finally agreed on one chair that we both loved. It wasn't the chair I came in for or saw on line, but it was 10X better. We spent a little more than we initially wanted to, but when you figure this is going to last us a long time, we went ahead and pulled the trigger.
Henry was wonderful dealing with and gave us a good and fair price on the massage chair.
We couldn't be more happy with our purchase and the service we got from Henry.
T. S. · San Jose showroom · Google review
We were very impressed with the selection of massage chairs and the service we received. We were able to take our time trying many different models. Shawun was knowledgeable and patient, explaining the features of each chair and helping us find one that both my wife and I liked. Michael was also very helpful. We really appreciated their friendly service and would definitely recommend this store.
S. C. · Pleasanton showroom · Google review
Henry at House of Massage Chairs provided truly exceptional service from start to finish. He spent a generous amount of time with my wife and me, helping us find the right massage chair for both of our needs. He patiently walked us through the different brands, features, and technologies, explaining each brand’s approach and how those differences translate into the actual massage experience. His knowledge and attention to detail helped us feel informed and confident in our decision.
What really set Henry apart was how far he went to help us beyond the store visit. He assisted with delivery and even helped us navigate the return of a massage chair we had recently purchased. That level of care and follow-through made a big difference to us.
Throughout the entire process, we felt that Henry genuinely cared about finding the best fit for us. If you’re considering a massage chair, I highly recommend visiting House of Massage Chairs and asking for Henry. Thank you, Henry, for your patience, expertise, and outstanding service!

Salesman Gabe spent time with us explaining the features of each chair and the differences between chairs. No pressure sales.
D. H. · Pleasanton showroom · Google review
We had a wonderful experience here! Henry was incredibly welcoming, knowledgeable, and professional. He took the time to understand what we were looking for and quickly helped us narrow down the options based on our preferences.
The store carries a great selection of different brands and models, probably one of the most comprehensive selections we’ve seen in the Bay Area. It was really convenient to be able to try so many different chairs in one place, and we found one we loved pretty quickly.
Henry also did a great job explaining the differences between the chairs, as well as the warranty and after-sales service for each option. We really appreciated how transparent and thorough he was—it made us feel very comfortable and confident about our purchase.
Overall, it was such a pleasant and stress-free shopping experience. Great selection, great service, and very knowledgeable staff. Highly recommend Henry and this store if you’re looking for a massage chair!
C. C. · San Jose showroom · Google review
We visited the store intending to buy a chair on father's day. Gabe's exceptional patience, comprehensive knowledge of all available chairs, and friendly, non-pressuring demeanor made the experience truly enjoyable. We spent over 3 hrs trying almost every chair, so much so that we didn't realize the mall had already closed. Despite this, Gabe graciously encouraged us to take our time and not rush our decision. Ultimately, we purchased a chair that exceeded our initial budget, but its quality has proven invaluable as we use it daily. Thank you Gabe again!
C. B. · Pleasanton showroom · Google review
We had such a great experience shopping here! Henry, the owner, was incredibly helpful and professional. He quickly understood exactly what we were looking for and, with his many years of experience, recommended a massage chair that turned out to be a perfect fit for us.
What really impressed us was how accurately he explained the differences between the chairs and what we would actually feel during the massage. Once we tried the chair he recommended, everything he described was spot on. He really helped us narrow down the options and feel confident about our final decision without ever making us feel pressured.
Henry is knowledgeable, patient, and genuinely cares about finding the right chair for his customers. We’re very happy with our purchase and the entire shopping experience. Highly recommend!
