Infinity IT-8500 Plus Massage Chair

S-Track Design — Neck to Lumbar Along Your Spine’s Natural Curve

The rollers follow the exact shape of your spine from your neck down to your lumbar region — hitting every tension point along the way rather than guessing at them.

Your spine has a natural S-curve, and the IT-8500 Plus’s track is engineered to match it. This means the four quad rollers stay in close, accurate contact with your back throughout the entire stroke length — from the cervical spine through the thoracic and into the lumbar — rather than losing pressure at the curves the way a straight-track roller does. The result is a more consistent, thorough, and therapeutically effective back massage with every session.

Four-Node Roller Mechanism — Five Massage Techniques

Four precision rollers work in tandem down your back with five selectable techniques — delivering a thorough, deep-tissue quality massage that two-roller systems cannot match.

The quad-node roller system uses four high-performance rollers arranged to deliver pressurized massage strokes from the top of the cervical spine continuously through to the lumbar region. Five technique options — including kneading, tapping, and shiatsu — let you tailor the quality of each stroke to what your muscles need that day. Long, continuous strokes from top to bottom of the track remove stiffness, reduce built-up tension, and promote circulation throughout the entire back in a single pass.

Decompression Stretch — Full Body Spinal Relief

Airbags grip your shoulders and legs simultaneously as the chair reclines, pulling gently in opposite directions to open and lengthen the spine in a way no roller massage can replicate on its own.

The Decompression Stretch is a full-body stretch program that combines chair movement with synchronized airbag compression. As the chair reclines through its range, shoulder airbags anchor your upper body while leg airbags hold the lower half, creating a measured, therapeutic traction along the full length of the spine. This is the feature that makes the IT-8500 Plus a genuinely different category of chair from a standard roller-and-airbag massage.

Spinal Correction and Waist Twist Therapy

Two distinct approaches to lower back relief — one intensive, one gentle — so you can match the treatment to how your back actually feels today.

The Spinal Correction feature takes the Decompression Stretch further: the chair reclines to near-flat — approaching true inversion — where gravity itself assists in reversing the compression that builds up from sitting and standing throughout the day. For days when the full correction is more than you want, Waist Twist Therapy uses the lumbar and hip airbags in an alternating sequence to introduce gentle lateral rotation through the lower spine, producing a looser, more mobile lower back without the intensity of full inversion.

Zero Gravity Recline

Your knees rise above your heart, your spine decompresses, and every roller stroke becomes more effective — zero gravity is where the IT-8500 Plus does its best work.

Originally developed from NASA research on optimal body loading during space launch, zero gravity positioning places you in a reclined angle where your body weight is distributed evenly across the chair rather than concentrated on your spine. In this position, breathing deepens naturally, circulation improves, and the S-Track rollers make full, consistent contact with your back. Two zero gravity settings let you find the angle that gives you the combination of support and decompression that works best for your body.

Zero Wall Space-Saving Technology

The chair slides forward as it reclines, so it can be placed directly against the wall without losing any recline range.

Standard reclining chairs require substantial wall clearance to reach full recline — often two feet or more. The IT-8500 Plus shifts its center of gravity forward on its base as it leans back, keeping the backrest close to the wall throughout the full recline range. This makes it practical for bedrooms, home offices, and living rooms where space is a genuine constraint.

Triple Roller Total Sole Reflexology

Three reflexology rollers per foot cover the entire sole — from heel to toe — targeting the pressure points that connect to the rest of the body.

Most chairs include a single row of foot rollers that can only address one band of the sole at a time. The IT-8500 Plus uses three rows of shiatsu rollers per foot, replicating the thumb-and-finger techniques of professional reflexology across the full surface area of the sole. Three speed settings let you adjust the intensity to match your sensitivity.

Lumbar Heat

Steady warmth at the lower back softens tight tissue before the rollers work it — making the massage more effective at the same intensity setting.

Heating modules built into the lumbar section of the backrest provide focused, adjustable warmth to the region where chronic tension accumulates most. The heat loosens muscle fiber and increases tissue pliability throughout the session, allowing the quad rollers to reach deeper with less resistance.

38-Airbag Full-Body Compression Therapy

Shoulders, arms, back, hips, legs, and feet are all addressed simultaneously — compression that covers the body from top to bottom in every session.

Thirty-eight airbags distributed across the shoulders, neck, back, arms, buttocks, legs, and feet inflate and deflate in coordinated sequences that replicate the feel of hands working the muscle tissue from outside. Multiple intensity levels let you adjust the compression from gentle to firm depending on how much your body can tolerate that session.

Body Scanning Technology

The chair measures the shape and curve of your spine at the start of every session and adjusts the roller starting position to match your body specifically.

Body scanning uses built-in sensors to map your height, shoulder position, and spinal curve before each massage begins. The roller assembly repositions itself to the correct location for your body rather than starting from a fixed default. This means the quad rollers make accurate contact with your actual pressure points from the first stroke, not after several minutes of repositioning.

Bluetooth® Speakers and SootheMe™ Nature Sounds

Stream your own audio wirelessly through headrest speakers, or choose from built-in nature soundscapes — without picking up your phone or interrupting the session.

Bluetooth® speakers mounted in the headrest connect to your phone or device to deliver music, guided meditations, or podcasts in the most immersive position — directly beside your ears while you are fully reclined. If you would rather not deal with your phone at all, the SootheMe™ nature sound library is accessible directly from the remote with no streaming required.

Apple® and Android™ App Functionality

Control the chair from your phone — programs, settings, and adjustments — without reaching for the remote.

The free Infinity app for Apple® and Android™ devices connects to the chair and gives you full control from your phone. If you already have your phone in hand for music or audio, you can manage the massage in the same place without switching between the app and the remote.

Rhythm Technique — Massage Synced to Your Music

The chair synchronizes its massage rhythm to the tempo of whatever you are listening to — a genuinely immersive experience that changes with every playlist.

Rhythm Technique links the timing of the roller and airbag movements to the beat of your music through the Bluetooth® connection. The result is a session that feels responsive and dynamic rather than mechanical — one of the IT-8500 Plus’s most distinctive and consistently praised features among regular users.

The IT-8500 Plus has earned its reputation as one of Infinity’s most enduring best-sellers because it does something most massage chairs in its category do not: it takes back pain seriously as the primary problem to solve. The Decompression Stretch, Spinal Correction, and Waist Twist Therapy are not marketing names for the same feature with different labels — they are three genuinely distinct back treatment modes that address the full spectrum of lower back stiffness and compression, from the aggressive (near-flat inversion where gravity actively assists in spine lengthening) to the gentle (lateral waist rotation that loosens the lower back without any inversion at all). For buyers dealing with chronic back discomfort, that range of options in a single chair is rare and meaningful.

The S-Track with near-flat reclining is the mechanical foundation that makes all of this work. Most S-Track chairs stop well short of horizontal because the track geometry does not allow the roller to stay in contact with the back at deep recline angles. The IT-8500 Plus was specifically engineered so that the S-Track’s effective range extends through the full inversion cycle — meaning the spinal correction program is not just a positional change but a true massage-and-stretch combination that works simultaneously. The four-node quad roller system delivers five distinct massage techniques along the full track length, each designed to address a different kind of muscle response.

Beyond the back, the triple foot roller system offers the broadest sole coverage in this category, and the 38 airbags address the shoulders, arms, hips, legs, and feet with layered compression. The Rhythm Technique — syncing the massage to music through the Bluetooth connection — and the built-in SootheMe™ nature sounds add a sensory dimension that makes the IT-8500 Plus easy to use daily rather than only when you have a specific problem to address.

This is the right chair for people who have chronic lower back stiffness or compression issues and want a chair that addresses those specifically through multiple therapeutic approaches. It is not the right chair for buyers who primarily want a shoulder and upper-body massage, or who want simultaneous upper and lower back roller coverage — the S-Track works sequentially, top to bottom, on a single mechanism. Call 888-612-8862 and we will tell you directly whether the IT-8500 Plus fits what you are dealing with.

What We Love

• Three distinct back treatment modes — Decompression Stretch, Spinal Correction (near-inversion), and Waist Twist Therapy all in one chair. Few chairs at any price offer this range of back-specific therapeutic options.
• Near-flat S-Track with true inversion capability — The spinal correction program leverages gravity itself to assist in decompression — a feature that requires precise track engineering and is not common.
• Four-node roller system with five techniques — Quad rollers deliver thorough, deep-tissue quality pressure across the full S-Track range with five selectable massage styles.
• Triple Roller Total Sole Reflexology — Three rows of shiatsu rollers per foot for the most comprehensive sole coverage available in this category.
• 38 airbags — full-body coverage — Compression at the shoulders, neck, back, arms, hips, legs, and feet simultaneously, with multiple intensity levels.
• Rhythm Technique — The massage syncs to the tempo of your music through Bluetooth. Distinctive, immersive, and one of the most consistently praised features among long-term owners.
• Body scanning for accurate roller placement — Sensors map your spine before each session and position the rollers correctly for your specific body — not a generic default.
• SootheMe™ nature sounds built in — No streaming required. A sound environment is accessible directly from the remote without your phone.
• App control for Apple® and Android™ — Full chair management from your phone when the remote is out of reach or you are already using your device for audio.

Worth Knowing

• The S-Track covers neck to lumbar only — not the glutes — Unlike L-Track chairs that extend coverage into the gluteus region, the IT-8500 Plus’s track ends at the lower lumbar. If glute and hamstring roller coverage is a priority for you, that is worth discussing before you order. The airbags do provide hip and buttock compression, but the rollers do not reach those areas.
• This chair is designed around back and spinal therapy first — The Decompression Stretch, Spinal Correction, and Waist Twist programs are what distinguish the IT-8500 Plus from comparable chairs. If your primary focus is shoulder massage, arm massage, or lower-body coverage rather than back and spinal work, there may be a better match. Call us and we will tell you honestly.
• Suggested user height range is 4’11” to 6’6” — If you are outside this range, call 888-612-8862 before ordering and we will give you a direct answer about fit.

Our Verdict

The IT-8500 Plus is the chair for buyers who need genuine spinal therapy — not just massage — and want multiple approaches to back decompression in a single chair. The combination of Decompression Stretch, near-flat Spinal Correction, and Waist Twist Therapy has made this one of Infinity’s longest-running best-sellers because it addresses the problem most buyers actually have. Best for people with chronic lower back compression, desk workers who need daily spinal relief, and buyers who want a chair built specifically around back and spinal health. Look elsewhere if your primary needs are glute and hamstring roller coverage or simultaneous upper and lower back treatment.

The Chronic Back Pain Sufferer

You have tried chairs that massage the back but do not change how it feels the next morning. The IT-8500 Plus is different because it does not just massage — it actively stretches and decompresses the spine through three distinct therapeutic programs. Owners with chronic compression and disc issues consistently describe the Decompression Stretch and Spinal Correction as the features that make a real, lasting difference.

The Daily Desk Worker

Sitting compresses the lumbar region and tightens the hips and lower back throughout the day. The IT-8500 Plus’s seven automatic programs — including dedicated Neck & Shoulder and Waist & Spine programs — give you a targeted session at the end of each day without needing to think about settings. The Rhythm Technique and SootheMe™ sounds make it easy to use consistently rather than only when symptoms are bad.

The Practical Buyer

The IT-8500 Plus is not a chair with features you will use once and forget. Body scanning, triple foot rollers, 38 airbags, app control, Bluetooth speakers, and the Rhythm Technique are all features that integrate naturally into a daily routine. This is a chair with a long ownership record — we regularly hear from buyers who have used theirs for five or more years and still reach for it every evening.

When to Consider a Different Chair

If you want roller coverage that extends into the glutes and hamstrings, the IT-8500 Plus’s S-Track does not reach those areas. An L-Track or Flex-Track chair would be a better fit for that priority.

If you want simultaneous upper and lower back roller coverage from two independent mechanisms, the Infinity Luminary Syner-D® is worth comparing — it uses dual Syner-D® mechanisms on a Flex-Track for a fundamentally different back massage experience. Call 888-612-8862 and we will walk through which approach fits your situation in about two minutes.
