Walking Technology

Unlike chairs that overlook the lower body, the Trion gives your legs equal attention. Independently adjustable leg rests move in a scissor action that mimics a natural walking motion, gently stretching the lower back, glutes, hamstrings and knees. Enable it through the SORA Mode auto programs — Core Comfort, Hamstring Harmony, Hip Sculptor, Cyclist's Bliss, Twist & Thrive, Dynamic Flex, Vitality Surge and Thigh Revival.

Scissor-action leg rests · Lower-body stretch · 8 SORA Mode programs

Duo Mech™ 4D+3D Mechanism

Two mechanisms, two jobs. The upper 4D mechanism works your back with a full range of massage styles and adjustable intensity, moving vertically, horizontally and in depth while varying speed and rhythm like a human masseuse. The lower 3D mechanism delivers a steady, deep massage to the glutes and upper hamstrings — so both halves of your body get relief at the same time.

Intelligent Health Detection

Grip the sensor handles and the Trion checks in with you before it goes to work. An integrated health monitor reads heart rate, heart rate variability, blood oxygen, microcirculation and a fatigue index, and its AI uses that data to build a massage tailored to how your body feels right now — not a fixed routine.

Self-Adaptive SL Flex Track

The Trion's extended SL track combines S and L tracks to follow your spine's natural curve from neck to hamstrings — and then goes further. A flexible, extendable section adjusts as the chair reclines, deepening the back stretch and keeping roller pressure consistent across the shoulders, spine, hips and thighs in every position.

Body Scan Technology

Every session begins with a full-body scan. The Trion detects your unique shape and size first, then positions the rollers to your proportions — so the shoulders, lumbar and hips get hit exactly where they should, whether you're 5'0" or 6'2".

Scans on every power-up · Rollers auto-position · Fits 5'0"–6'2"

2-Stage Zero Gravity & Space-Saving Recline

Lean back into two zero-gravity stages that distribute your weight evenly, lift your legs and take the pressure off your spine for a deeper, near-weightless massage. Space-saving technology slides the chair forward as it reclines, so it reaches full recline just 2 inches from the wall.

50-Cell Air Compression

Fifty strategically placed air cells deliver rhythmic compression across the shoulders, arms, waist, calves and feet, releasing tension and boosting circulation. Layered over the rollers and the Walking Technology, it turns a back massage into a complete, full-body session.

Shoulders to feet · Multi-zone compression · Circulation boost

3 Active Arm Rollers Per Side

Each armrest houses three active rollers that knead the forearms and wrists while the air cells compress around them — relieving tension and improving blood flow in a zone most massage chairs leave to airbags alone.

3 rollers each arm · Rolling + compression · Forearm & wrist relief

Lumbar & Calf Heat Therapy

Heating pads in the lower back and calves warm to roughly 75–83°F, loosening tight muscles and improving circulation right where most of us hold tension — and making every roller and air-cell pass feel deeper.

Heated Foot Rollers & Automatic Foot Extension

Three acupressure rollers per foot work from heel to the ball of the foot, mimicking hand movements on key pressure points, with the middle rollers offering three levels of soothing heat. The footrest extends automatically up to 6 inches to match your leg length, so every user gets a proper fit.

12 Auto Programs & 6 Manual Styles

Twelve one-touch programs are grouped by goal — Train (Yoga Warrior, Deep Tissue, Power Up), Boost (Performance Max, Sports Stamina, Muscle Melt), Target (Neck & Shoulder, Shape & Tone, Back Strength) and Recover (Thai Stretch, Sports Recovery, Acupressure Balance). Or build your own with six manual styles: Kneading, Sync, Vibration, Tapping, Shiatsu and Acupressure, all from the touchscreen remote.

"Hey Alice" Voice Command

Once you're reclined, you shouldn't have to reach for anything. Say "Hey Alice" followed by a preset command to start, stop or adjust your massage completely hands-free. For quick tweaks, the side control panel puts heat, volume, zero-gravity positions and backrest and legrest adjustments at your fingertips.

Set your phone on the built-in charging pad and it powers up while you unwind — no cable to fumble for.

USB Charging Port

A USB port in the armrest keeps a second device topped up through every session.

Bluetooth Speakers

Stream music or a guided meditation through speakers built into the headrest for a fully immersive escape.

Quick Shortcut Panel

Heat, volume, zero gravity and backrest/legrest adjustments on the armrest — no remote required.
