House of Massage Chairs · Exact-Model Guide
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 is a premium 4D massage chair listed at $8,999.00 by HMC. 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.

- 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.

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.

The Gen Max 4D is a comfort and relaxation product. Manufacturer feature names may use wellness-oriented language, but the chair is not a medical device and is not presented here as diagnosing, treating, curing, or preventing any condition.
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.
Outside that range, confirm shoulder and footrest fit with HMC before purchase.
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.

08 · The Decision
Who the Gen Max 4D 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.

Contact HMC to confirm current showroom availability for the Infinity Gen Max 4D before you visit.
The Decision
Infinity Gen Max 4D.
Choose it 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 verified body fit, room plan, and delivery route.
