SEE IT IN ACTION

A closer look at the Trion Flex Duo.

See how the chair moves, reclines and brings its dual-mechanism massage system together before exploring the details below.

YOUR PLACE TO RESET

More than sitting still.

The Trion Flex Duo is built for the moments when you want to leave the day behind and give your whole body time to unwind.

Its dual massage mechanisms, flexible track and lower-body systems work together so the experience continues from your back through your legs and feet.

Choose a program, settle in and let the chair bring the movement, compression and warmth together for you.

HOW IT COMES TOGETHER

How does the Trion Flex Duo create that experience?

This is where its combination of movement, massage and intelligent controls comes in.

WALKING TECHNOLOGY + SL FLEX TRACK

A chair designed to move with the experience.

Walking Technology and the flexible SL track add movement to the lower body while the massage path follows the natural shape of the back and continues beneath the seat.

SORA MODE PROGRAMS

The Trion Flex Duo’s Walking Technology can be activated through these eight automatic programs in SORA Mode.

  • Core Comfort
  • Hamstring Harmony
  • Hip Sculptor
  • Cyclist’s Bliss
  • Twist & Thrive
  • Dynamic Flex
  • Vitality Surge
  • Thigh Revival

SELF-ADAPTIVE FLEXIBLE SL-TRACK

A deeper stretch that moves with you.

The Trion Flex Duo integrates a flexible track system with an extendable feature that adjusts as the chair reclines, enhancing back stretching and delivering a thorough massage from the neck and shoulders down to the spine, hips, and thighs.

Why it mattersAs the chair reclines, the track adapts to keep the massage connected from the shoulders through the thighs.
Extended SL track following the spine from neck to hamstrings

SL-TRACK SYSTEM

More of your body, in one continuous path.

The extended SL track combines S and L tracks to effortlessly follow your spine’s natural curve and reach from neck to hamstrings, covering more areas for faster recovery.

Why it mattersThe extended path reaches beyond the back to include the hips and hamstrings in the massage.
Trion Flex Duo dual 4D and 3D massage mechanisms

DUO MECH™ 4D + 3D

Two massage mechanisms working together.

The Trion Flex Duo combines 4D and 3D massage mechanisms rather than relying on a single roller system to create the entire massage.

Why it mattersDifferent areas can receive mechanical massage as part of one coordinated full-body session.

INTELLIGENT VOICE COMMAND

Relax without reaching for the controls.

The Trion Flex Duo has built-in voice control for a hands-free experience. Say “Hey Alice,” followed by a preset command, to control the chair without interrupting your massage.

Why it mattersMake adjustments while you stay comfortably reclined, without reaching for the touchscreen.

INTELLIGENT HEALTH DETECTION

A massage informed by your scan.

The Trion Flex Duo’s integrated monitor displays five wellness readings. The chair uses the scan results to guide an intelligent massage program tailored to the information it gathers.

  1. Heart rate
  2. Blood oxygen
  3. Microcirculation
  4. Heart rate variability
  5. Fatigue index
Why it mattersThe scan offers a more personal starting point for your massage. Readings are for wellness reference only.

BODY SCAN TECHNOLOGY

A massage mapped to your body.

At the start of a session, the Trion Flex Duo scans your body’s contours and size. Its massage rollers then adjust their position to better match your proportions.

Why it mattersThe rollers begin in positions suited to you, so the massage feels more precisely placed from the start.

4D MASSAGE MECHANISM

Movement that feels more human.

The Trion Flex Duo’s 4D mechanism moves vertically, side to side, and in and out to vary massage depth. Changes in speed and rhythm add another dimension to the experience.

Why it mattersPressure and pace can change throughout the massage, creating a more nuanced feel than one repeated motion.

2-STAGE ZERO GRAVITY RECLINING

Settle into a more supported recline.

Choose between two zero gravity positions as the Trion Flex Duo tilts back and supports your body more evenly. The reclined posture can ease pressure on your back and make it easier to relax into the massage.

Why it mattersWith your weight more evenly supported, you can focus on the massage instead of finding a comfortable position.

RELAXING 3 ARM ROLLERS

A gentler touch for your arms.

Three active rollers on each side massage the arms while air compression adds a gentle squeeze. The two motions work together for a more complete arm massage.

Why it mattersYour arms receive focused rolling massage alongside the chair’s air compression, helping you settle more fully into the experience.
Trion Flex Duo air compression zones at the shoulders, arms, back, hips, calves and feet

50-CELL AIR COMPRESSION MASSAGE

A gentle embrace from shoulders to feet.

Fifty air cells around the shoulders, arms, back, hips, calves and feet inflate and release to create a gentle, rhythmic squeeze. The compression works alongside the chair’s roller massage for a fuller body experience.

Why it mattersMore of your body is included in the session, with soft compression complementing the targeted rollers.
Trion Flex Duo heating zones at the lumbar area and calves

LUMBAR & CALVES HEATING THERAPY

Soothing warmth from back to calves.

Heating pads in the lumbar area and calves add gentle warmth as you recline. They complement the massage with comfort in two places where tension can build.

Heating pad temperature: approximately 75–83°F.
Why it mattersWarmth adds another layer of comfort while the rollers and air compression do their work.

HEATED FOOT ROLLERS

Let the comfort reach your feet.

Three rollers in each footwell work from heel to the ball of the foot, with a motion designed to feel like a focused foot massage. The middle rollers add soothing warmth with three heat settings.

Why it mattersYour feet get their own rolling massage and adjustable warmth as part of the full-body session.

AUTOMATIC FOOT EXTENSION

More room to stretch out.

The footrest adjusts to different leg lengths and extends up to 6 inches, helping you find a comfortable fit as you settle into the chair.

Why it mattersA better fit keeps your feet comfortably positioned for the rollers and calf massage.

BEFORE DELIVERY

Make sure the Trion Flex Duo fits your home.

A few measurements before delivery can make the path into your room much easier to plan.

Trion Flex Duo doorway widths: 33 inches assembled and 30 inches disassembled

MINIMUM DOORWAY

Measure the narrowest point before delivery.

Use the smallest clear opening along the delivery path so you know the chair can move through the doorway comfortably.

Measuring guide

  • Measure the narrowest inside width of the door frame, then allow 2 inches of clearance in total — 1 inch on each side.
  • Use a standard measuring tape and measure the actual clear opening, not the outside dimensions of the frame.
  • If the door cannot open fully, open it as far as possible and measure from the edge of the door or hinge to the opposite side of the opening.
  • If trim, a rounded wall or another feature projects into the opening, measure from the point that extends furthest into the delivery path.

Before you decide

Understand what you are buying.

What does Duo mean?

Duo means the chair has two separate massage mechanisms. They can work on different areas at the same time: typically one massages the back while the other targets the glutes and upper thighs. The combination varies by model, such as 4D + 3D or 5D + 4D.

What does 4D + 3D actually mean?

3D adds adjustable in-and-out depth to roller movement. 4D builds on that with more dynamic speed and rhythm. On a dual 4D+3D chair, two different mechanisms contribute to the same session.

What is an SL-Track?

An SL-Track follows the natural curve of the spine and extends beneath the seat toward the glutes. Flexible versions can articulate as the chair changes position.

What are air cells?

Air cells are inflatable chambers that apply controlled compression around areas the rollers cannot directly reach. Placement and programming matter as much as the raw number of cells.
