Osaki Aeris 4D Duo Massage Chair

4D Dual Massage Mechanism

Instead of a single roller carriage, the Aeris uses two independent sets of 4D rollers that run at the same time, so one set can focus on the neck and shoulders while the other works the lower back and seat.

Each set travels up and down, moves side to side, and presses in or eases out while varying its pace, which gives the massage a layered, hands-on rhythm.

SL-Track System

The SL-Track curves along the spine and then bends under the seat, letting the rollers travel from the base of the neck through the back to the glutes.

That continuous path means the hips and seat are part of the same massage instead of a separate zone.

Body Scan

Before a session, sensors check your height and shape to find where your neck, shoulder line, and spine sit.

Roller positions are adjusted to match, so the massage lines up with your body rather than an average frame.

Intelligent Health Detection

Press the Smart button and rest a fingertip on the armrest sensor, and the Aeris takes readings Osaki lists as blood oxygen, HRV, microcirculation, and a fatigue index.

Its AI analysis uses those results to suggest a program for the session. The readings are a guide for choosing a massage, not a medical assessment.

44-Cell Air Compression

Forty-four air cells placed around the shoulders, arms, waist, calves, and feet inflate and release in a steady pattern to squeeze and hold each area.

The Airbag button switches between kneading, pulsing, and alternating air modes, so you can change how the compression feels.

Detailed Calf Massage

Dedicated calf rollers knead the backs of the lower legs while the calf-rest bumpers shift in time with them.

Working together, they wrap the calves in a rolling, rhythmic motion that goes beyond simple air squeezing.

Specialized Foot Rollers

Rollers under each foot carry raised reflexology ridges that press into the soles as they turn.

The Foot Roller button on the armrest cycles through three speeds, or switches them off when you only want air on the feet.

Lumbar Heating Therapy

Heating elements in the lower backrest deliver gentle warmth, roughly 75–83°F according to Osaki, across the lumbar area.

Three heat levels are available from the armrest, so the warmth can stay subtle or become more noticeable.

Waist Cooling Technology

Waist cooling sends a light stream of cool air toward the waist during the massage.

It has three levels of its own and pairs with the heat setting, giving you a choice between warmth in winter and a fresher feel on warm days.

2-Stage Zero Gravity Recline

The Zero-G button moves the chair into Relaxing or Deep Relaxing zero gravity, tilting you back with the legs raised so your weight rests more evenly across the seat and backrest.

Thanks to space-saving technology, the chair slides forward as it reclines, so it needs only minimal room behind it.

One-Touch Rocking Mode

A dedicated Rocking button sets the whole chair swaying slowly back and forth, like a cradle.

Press it again to stop, or leave it running to add a soft, swaying motion to any program.

7.5" Touchscreen Remote

A 7.5-inch touchscreen on an armrest stand lays out programs, settings, and health results on a large, clear display.

The screen sits in a holder on the armrest, and its cable locks into a port on the chair with a screw cap.

12 Automatic Massage Programs

The presets fall into four groups: Power Stretch, Energize, and Tranquil Massage; Deep Tissue, Clear Mind, and Refresh; Upper Body, Back & Spine, and Lower Body; and the daily-routine trio of Wake Up, Power Nap, and Sleep Mode.

Repeated presses of the power button step through the automatic programs, or you can pick one directly on the touchscreen.

6 Manual Massage Techniques

Manual mode lets you choose the technique yourself: kneading, sync, tapping, rubbing, knocking, or shiatsu.

It is a simple way to build a session around the stroke you enjoy most.

Adjustable Massage Settings

Turning the rotary dial around the power button raises or lowers roller strength without opening a menu.

Heat, waist cooling, and foot roller speed each offer three levels, and the air cells switch between three compression modes.

Intelligent Voice Control

Say “switch to voice mode,” then name a program or say pause, continue, or power off to run the chair hands-free; the voice feature works offline.

Automatic Extendable Footrest

The leg rest extends automatically by as much as 7 inches, so it fits a wider range of heights.

360° Rotating Footrest

Osaki lists a footrest that can turn through 360° in either direction to keep the feet and lower legs moving during the massage.

Removable Foot Padding

Removable padding inserts in the footrest let you add extra cushioning under the feet or take it out for a firmer feel.

Bluetooth Speakers

Speakers in the headrest wings play music, podcasts, or ambient sound from a paired device.

Armrest Quick Buttons

A rotary dial and eight shortcut buttons on the armrest handle the health check, air, rocking, zero gravity, heat, cooling, foot rollers, and Sleep Mode.

Wireless & USB-A Charging

A wireless charging pad and a USB-A port in the armrest keep a phone topped up during the session.

Sleep Mode

With Sleep Mode on, the chair stays reclined after the massage ends and powers down two minutes later so you can keep resting.
