Syner-D® Dual Back Massage Mechanism — Two Mechanisms, One Choreographed Session

Two independent roller assemblies work your back and gluteus region simultaneously, combining 2D, 3D, and 4D technologies in a single session — a level of coverage that no single-mechanism chair can replicate.

The Syner-D® system is the defining feature of the Nokori M980 and Kyota’s most advanced engineering achievement. Rather than one roller assembly traveling back and forth across your spine, two separate mechanisms work in coordinated harmony — each applying its own combination of 2D, 3D, and 4D roller motion to different parts of the back and glutes simultaneously. The result is a massage that is more thorough, more continuous, and more therapeutically effective than any single mechanism can produce, because no area ever has to wait for the other to finish.

J-Track Flex Track — L-Track Coverage With S-Track Stretch Capability

Every other track design forces a compromise. The J-Track eliminates it — full neck-to-glutes coverage and genuine spinal decompression stretch from the same track.

Standard L-Tracks reach the glutes but cannot produce the spinal stretch of an S-Track. Standard S-Tracks stretch beautifully but stop at the lumbar. The Kyota J-Track opens slightly upon recline, combining the full-body coverage of an L-Track with the superior spinal decompression mechanics of an S-Track in a single design. The dual Syner-D® mechanisms travel this full track simultaneously, producing an unbroken massage from neck through glutes at every recline position.

TrueFit™ Body Scanning — Mapped to Your Exact Measurements

Before the session starts, the M980 maps your body’s size and shape so both roller mechanisms engage the correct anatomy — not a factory default that fits nobody perfectly.

TrueFit™ scanning technology reads your shoulder height, spinal curve, and body proportions before every session. Both Syner-D® mechanisms then calibrate their travel path to your specific measurements, ensuring that pressure from the dual rollers lands on the right muscles at the right depth throughout the entire massage. The scan happens automatically at the start of each session, and saved memory profiles let returning users skip the process entirely.

Complete Calf™ Kneading + Oscillation — The Most Thorough Calf Treatment Available

Kneading rollers work the back of the calf while orbital oscillation engages the sides — both simultaneously, with airbag compression wrapping around the outside. Nothing comparable exists on other chairs.

Most chairs apply airbag compression to the calves and call it done. The Nokori M980’s Complete Calf™ system is fundamentally different: dedicated kneading rollers embedded in the back of the leg rest work through the calf muscle from behind, while orbital oscillation mechanisms on the sides move in a circular pattern that imitates the motion of skilled hands. Both systems run simultaneously while airbag compression applies adjustable external pressure, creating a three-dimensional calf treatment that reaches tension that airbags and rollers alone cannot touch together.

Triple Foot Roller Total Sole Reflexology

Three shiatsu rollers per foot cover the full sole from heel to toe — the broadest reflexology coverage available in a massage chair today.

Most massage chairs use one or two foot rollers that cover only part of the sole. The M980 uses three shiatsu rollers per foot, providing complete coverage of every pressure point across the entire sole from the heel through the arch and to the toes. The foot reflexology points stimulated by these rollers correspond to muscle groups and organ systems throughout the body, making thorough foot coverage a meaningful part of a complete wellness session rather than a peripheral feature.

TrueFit™ Footrest Extension — Proper Fit for Every Height

When the footrest is the right length for your legs, the Complete Calf™ rollers and triple foot reflexology system engage correctly. When it is not, both systems miss their targets.

The TrueFit™ footrest extension adjusts to accommodate the full range of heights the M980 serves — 5’2” to 6’4” — so the lower-leg treatment system delivers the same quality of coverage to a 5’3” user and a 6’3” user. This is particularly relevant for a chair with the M980’s level of calf and foot engineering, where the precision of contact matters as much as the mechanism producing it.

Zero Gravity Recline and Zero Wall Fit™ Space-Saving Technology

Your feet rise above your heart, spinal compression releases, and the Syner-D® mechanisms work more deeply — all while the chair slides forward to keep its distance from the wall to just a few inches.

Zero gravity elevates the legs above heart level, distributing body weight evenly across the backrest and removing the gravitational load on the spine that keeps back muscles in partial contraction even at rest. In this position, the dual Syner-D® mechanisms produce noticeably deeper results at the same intensity setting because the muscles alongside the spine are no longer working to support body weight. The Zero Wall Fit™ mechanism slides the seat forward during recline rather than swinging the backrest backward, allowing the chair to sit naturally against a wall without needing to leave a large gap behind it.

Lumbar Heat Therapy

Steady warmth in the lower back softens the muscles that surround the lumbar before and during the roller work — allowing the Syner-D® mechanisms to work more effectively at any pressure setting.

Heating modules positioned in the lower back region generate a consistent warmth that loosens the dense muscle tissue around the lumbar spine. Heat and mechanical pressure addressing the same tissue in the same session produces better outcomes than either alone — the warmth removes the initial resistance that keeps tight muscles from responding to roller pressure, and the rollers then work through tissue that has already begun to release.

Chromotherapy Lights — Color Spectrum Ambient Therapy

Chromotherapy uses specific colors of light to support physical and mental balance — built into the sides of the chair so the ambient environment of the session works alongside the massage itself.

Chromotherapy is rooted in the therapeutic use of the color spectrum to influence physical and emotional states — the same principle behind spa and wellness environments that use colored light to enhance relaxation. The M980’s chromotherapy LEDs illuminate the sides of the chair, creating an immersive environment around the session that reinforces the relaxation response the massage is building rather than leaving the ambient space neutral.

Integrated Air Ionizer

The session environment includes the air around you — a small vent near the headrest continuously emits negative ions during your session to support the quality of what you are breathing.

The air ionizer built into the M980’s headrest area emits negatively charged ions that help reduce airborne pollutants near the breathing zone during the session. Research associates negative ion environments with improved alertness and reduced stress — the same quality of air commonly noticed near waterfalls, after rainfall, or in high-altitude environments. It is a detail that contributes to leaving a session feeling refreshed rather than simply looser.

SootheMe™ Sound Therapy — Built-In Soundscapes, No Streaming Required

Nature sounds built directly into the chair — accessible from the remote — so your session does not depend on finding something to stream, and the soundscape it plays is designed to support relaxation, not interrupt it.

The SootheMe™ system stores a library of nature soundscapes directly on the chair and makes them accessible through the tablet remote. Select a soundscape from the menu and it plays through the premium Bluetooth speakers throughout your session without requiring a phone connection, a streaming service, or any setup. For users who want a complete and self-contained relaxation environment, this means the chair handles audio, lighting, ionization, heat, and massage all from a single interface.

Premium Bluetooth® Speakers and Touchscreen Tablet Remote

Pair your phone and stream audio through high-quality speakers, or play built-in SootheMe™ soundscapes — all controlled through a full touchscreen tablet that puts every feature of the chair in one place.

The M980’s premium Bluetooth® speakers deliver audio throughout the session at a quality that matches the chair’s overall tier. The tablet remote provides touchscreen access to every function — auto programs, manual settings, chromotherapy, sound therapy, airbag intensity, heat, recline, and memory programs — in a clean interface that does not require navigating multiple separate controls. Voice command adds hands-free control for adjustments without reaching for the tablet while reclined.

Quick Access Control Panel + Joystick Control

The most commonly used controls are immediately accessible on the armrest — no need to reach for the tablet remote for quick adjustments mid-session.

The integrated side control panel and joystick give you direct access to key chair functions directly from the armrest. The joystick control is particularly intuitive for adjusting the position and focus of the roller mechanisms without interrupting the session or breaking the state of relaxation you have built. Three control options — tablet remote, side panel, and voice command — means every type of adjustment is always accessible in the most natural way for the moment.

Wireless Charging Pad and USB Port

Set your phone on the armrest pad and it charges throughout the session — no cable, no searching for a port, no watching the battery level.

The wireless charging pad embedded in the armrest charges compatible phones automatically on contact. A USB port sits alongside it for wired charging when needed. Both are integrated into the armrest so your phone remains within reach during the session whether you are using it for Bluetooth audio, voice commands, or simply keeping it accessible.

MyMassage™ Memory Programs

Once you have found the exact session that works for you, save it — and return to it instantly, every session, without adjusting anything.

MyMassage™ memory slots let you save your preferred combination of massage technique, intensity, body zone targeting, heat, airbag level, and recline position as a single recall. For multi-user households, each person can store their own configuration and return to their personalized session from the first tap without navigating through settings.

The M980 Syner-D® is Kyota’s most sophisticated engineering achievement and one of the most capable massage chairs available at any price. What makes it categorically different from every other chair is the Syner-D® dual mechanism: two independent roller assemblies choreographed to work your back and glutes simultaneously, each drawing on 2D, 3D, and 4D roller technologies in combination. This is not a marketing distinction — it is a fundamentally different experience. Two areas of your back receive uninterrupted attention at the same time, with no area waiting its turn while the single mechanism travels elsewhere. Owners who have used other premium chairs consistently describe the Syner-D® session as unlike anything they expected.

The J-Track Flex Track solves the long-standing design compromise between S-Track and L-Track coverage. By opening slightly upon recline, it delivers both the full-body coverage of an L-Track and the spinal decompression stretch mechanics of an S-Track in a single design — the dual mechanisms traveling its full length from neck through glutes. The Complete Calf™ system combines dedicated kneading rollers with orbital oscillation and simultaneous airbag compression, producing a lower-leg treatment that is a meaningful part of the session in its own right, not an afterthought. The triple foot rollers per foot achieve the broadest reflexology coverage in the category.

The M980 is available here as a Certified Pre-Owned unit — factory refurbished by Kyota and certified to be in perfect working order, carrying the same full 4-year warranty as a new chair. There may be minor cosmetic blemishes from prior shipping; call us at 888-612-8862 and we will send you photos of the actual unit before you commit. For buyers who want flagship performance with the peace of mind of a full manufacturer warranty, the CPO M980 is one of the most compelling chair values available.

This chair is best for buyers who want the most complete and therapeutically advanced massage chair session available and are ready for it. It is not the right fit for anyone who prefers a very gentle massage — the intensity range runs 1 through 9 and the Syner-D® dual mechanism produces results at even its lower settings that exceed many chairs at their maximum. Call 888-612-8862 and we will give you an honest answer about whether the M980 CPO is the right fit for your situation.

What We Love

• Syner-D® dual mechanism combining 2D, 3D, and 4D — Two independent mechanisms working simultaneously. Back and glutes addressed at the same time, continuously, at a level of thoroughness no single-mechanism chair can match.
• J-Track Flex Track — The only design that simultaneously delivers L-Track full-body coverage and S-Track spinal decompression stretch. The dual mechanisms travel it from neck to glutes without interruption.
• Complete Calf™ Kneading + Oscillation — Kneading rollers from behind, orbital oscillation from the sides, and airbag compression from the outside — all simultaneously. The most thorough calf treatment we know of in any massage chair.
• Triple foot rollers per foot — Three shiatsu rollers covering the complete sole from heel to toe. The broadest reflexology coverage in the category.
• Full-body wellness environment — Chromotherapy lighting, integrated air ionizer, SootheMe™ built-in soundscapes, lumbar heat, and premium Bluetooth® speakers create a complete wellness environment without needing anything external.
• Intensity range 1–9 — The widest intensity range we carry, covering genuinely gentle to deeply therapeutic — making this chair workable for a wider range of users in the same household than most premium chairs at this tier.
• TrueFit™ body scanning — Automatically calibrates both mechanisms to your shoulder height and spinal measurements before every session.
• Three control modes — Touchscreen tablet, quick access side panel with joystick, and voice command — covering every preference and every posture without awkward reaching.
• Same 4-year warranty on the CPO unit as a new chair — Factory certified by Kyota and fully warranted. The peace of mind of a new chair purchase at a significantly lower investment.

Worth Knowing

• Certified Pre-Owned units may have minor cosmetic blemishes — Factory refurbished by Kyota and certified to perform like new, but prior shipping may have left minor surface marks. Call 888-612-8862 and we will send you photos of the specific unit before you order.
• This is a serious, firm chair at every setting — The intensity scale runs from 1 to 9 and the Syner-D® dual mechanism produces more effective results at lower settings than most chairs deliver at their maximum. If a very gentle, surface-level massage is your primary goal, this chair may exceed what you are looking for.
• Height range is 5’2”–6’4” — Users shorter than 5’2” may find the roller path starts too low for their neck and shoulder position. Worth confirming before ordering if you are near that lower limit. Call 888-612-8862 and we will give you a direct answer.

Our Verdict

The Kyota Nokori M980 Syner-D® is one of the most comprehensively engineered massage chairs available — and in Certified Pre-Owned form, it carries the same full 4-year warranty as a new unit. The Syner-D® dual mechanism is not a specification on a sheet; it is a different category of experience. Best for buyers who want the most therapeutically complete back, calf, and foot session available and are ready for a chair that will challenge any expectation they have from prior massage chair experience. Look elsewhere if a very gentle massage is the primary goal, or if a user in the household is below 5’2” in height.

The Buyer Who Has Found Every Other Chair Unsatisfying

You have tried massage chairs — possibly several — and found them lacking. Too gentle, too slow to cover the areas that need attention, or simply not producing the kind of thorough, relieving result you were expecting. The Syner-D® dual mechanism addresses the most common root cause: a single mechanism that has to choose between areas, leaving the rest waiting. Two mechanisms working simultaneously eliminates that constraint entirely.

The Active or Athletic Recovery User

Full dual-mechanism back and glute work, Complete Calf™ kneading and oscillation, triple foot reflexology rollers, 1–9 intensity range, lumbar heat, and a zero gravity position that amplifies the effectiveness of all of it — the M980 is built to produce real recovery results at the end of any training day you choose, at the intensity level your body needs that day.

The Wellness-Focused Buyer Who Wants a Complete Environment

Chromotherapy lighting, integrated air ionizer, SootheMe™ soundscapes, premium Bluetooth® speakers, lumbar heat, and one of the most capable massage mechanisms available — all in one chair, all controlled from a single tablet interface. For buyers who approach relaxation and recovery as a whole-environment practice rather than a single mechanical tool, the M980 is purpose-built for that.

When to Consider a Different Chair

If you prefer a brand-new chair with the same dual-mechanism back massage concept, the Osaki OS-Pro 4D DuoMax is a current production alternative with its own dual-mechanism approach, piano key arm massagers, and 36-airbag compression system. The two chairs address the same core therapeutic goal through different engineering approaches.

If your budget or space requirements point toward a different tier, the Osaki OS-4D Pro Maestro LE or Osaki Platinum Solis 4D+ are strong single-mechanism alternatives worth discussing. Call 888-612-8862 and we will walk through the comparison in about two minutes.
