Automatic body scan
The body scan helps the chair locate your body and position the massage before your session.
Meet the Osaki One

A firsthand review from The Wellness Doc
See the Osaki One Pro 4D in Action
I worked directly with Osaki to help develop the Osaki One Pro 4D. In this video, I'll walk you through the chair, demonstrate its standout features, and explain what makes it different from other massage chairs I've tested.

Watch my firsthand review to see the arm paddles, calf rollers, foot massage, and stretching features before deciding whether the Osaki One is the right chair for you.
Your massage, your settings
Adjustable 4D rollers
The Osaki One combines up-and-down, side-to-side, and in-and-out roller movement with adjustable speed, depth, and intensity. Change those settings to find the level of massage that feels right for you.
Attention beyond your back
Arm paddles and rollers
The arm massage uses paddles and rollers to create a gentle, wave-like kneading motion. It adds a different sensation to your session than air compression alone.
A closer look at lower-leg massage
Calf rollers
Rollers behind the calves provide a kneading-style massage. If lower-leg massage is high on your wish list, this is a feature worth looking at closely.
More than a footrest
Foot rollers and vibration
Dual foot rollers work beneath your feet, while Achilles tendon bumpers and foot vibration add to the foot-massage experience. Rollers, compression, and vibration create different sensations rather than one repeating motion.
Settle in and make it your own
SL-track massage
The track guides the back rollers along your spine and beneath the seat for extended massage coverage.
Three-stage zero gravity
Choose from three zero-gravity positions to adjust your reclining experience.
Heat in three areas
Warming pads in the lower back, calves, and feet add another layer of comfort.
32-cell air massage
Airbags provide compression massage that complements the roller mechanisms.
Adjustable fit
Adjustable shoulder airbags and an automatically extending footrest help you settle into your session.
Simple ways to start your session
Choose from 24 automatic massage programs or use six manual modes: kneading, percussion, acupressure, flap, slap, and mixture. The touchscreen lets you browse the options, while voice control and shortcut controls give you additional ways to operate the chair.
Built-in Bluetooth speakers let you listen to your own audio, and a wireless charging pad adds convenience for compatible devices.
Plan for your body and your room
The Osaki One measures 32 inches wide, 66 inches long, and 44.5 inches high upright. Fully reclined, it measures 32 inches wide, 75 inches long, and 39 inches high. Its space-saving design slides forward as it reclines and requires 5.5 inches of clearance behind the chair.
The listed minimum doorway width is 32 inches assembled or 25.2 inches with components disassembled for delivery. Measure the clear opening with the door open, and check corners, stairs, and the full delivery route. Discuss disassembly and reassembly with your delivery team before ordering.
The seat is 21.5 inches wide. Shoulder airbags offer three adjustment settings: 23, 20, and 18 inches. The footrest automatically extends up to 8 inches. These measurements can help you assess fit, but comfort also depends on your body proportions and massage preferences.
