Forearm Massage Too Strong? Turn the Piano Mechanism Off.

Built into each armrest is Osaki's piano mechanism. Picture someone playing the piano along your forearm: it presses in a rolling, finger-like rhythm while air compression squeezes the arm, for a stronger forearm massage. If that's more than you want, every DuoMax SE lets you switch the piano mechanism off and keep just the air compression for a gentler feel. On the original DuoMax, whether you can turn it off depends on when the chair was made.

Intelligent Body Sensing

Before it starts, the DuoMax SE checks in with you. Its AI sensors read how you're feeling that day, then shape a massage that fits — not a one-size-fits-all program.

Duo Mech™ 4D+4D Mechanism

At its core is the Duo Mech™ dual 4D+4D mechanism — an 8 roller-track system that mimics human-like movement. Quad precision rollers adjust depth and speed in real time, delivering a targeted, deeply relaxing massage.

SL Flex Track

The DuoMax SE reinvents SL-track technology with a flexible design that adjusts its angle relative to the backrest — hugging the natural curve of your back for comprehensive coverage from your neck and shoulders down to your hamstrings.

Adjustable track angle · Neck-to-hamstring reach · Fits every body

2 Heated Jade Cores

Heated jade cores glide along your body's contours, blending massage with soothing warmth. Dedicated lower-back heat adds extra comfort right where most of us hold tension.

Zero Gravity & Space-Saving Recline

Inspired by NASA, the zero-gravity position reclines you into a near-weightless state that lifts your legs toward heart height for a deeply relaxing recline. Space-saving technology means it needs just 5.5 inches of wall clearance to fully recline.

Calf Kneading, Foot Rollers & Auto Footrest

The DuoMax SE doesn't skip the legs. Vertical calf rollers and airbag compression deliver a deep calf massage, while specialized foot rollers — two per foot — work the soles of your feet. An automatic footrest extends up to 7.8 inches for any height.

38 Air Cells

A full network of 38 air cells delivers rhythmic compression across the shoulders, arms, hips, calves and feet for a soothing squeeze from head to toe. Layered with the rollers, it turns a back massage into a complete, full-body experience.

Piano-Key Arm Massage

The piano-key arm massager gently cradles your arms and presses them in a harmonious, wave-like rhythm. It covers the arms — an area most massage chairs overlook entirely — for a massage that feels truly complete.

20 Auto Programs & 11 Techniques

Choose from 20 one-touch programs — from Total Relax and Stress Release to Thai Massage and Sweet Dream — or take control with 11 manual techniques including 4D modes, Shiatsu, Tapping and Kneading. There's a routine for every mood and moment.
