Osaki One Pro 4D

The Osaki One Pro 4D is a full-body massage chair built around two things most chairs compromise on: how deep the rollers go, and how far down your body they reach. The 4D mechanism lets you set roller depth rather than accepting a fixed pressure, and the SL-track runs in one unbroken path from the base of the neck, around the tailbone and forward under the seat — so glutes and hamstrings get worked, not just your back. Available in Black, Brown and Taupe. Automatic Body Scan — Maps your shoulders, spine and hips before the first pass, so roller paths fit your frame instead of a template. 4D Mechanism — Adjustable roller depth, with massage speed that shifts as you change it. SL-Track System — One continuous rail from the neck, around the tailbone and under the seat. Space-Saving Design — Slides forward as it reclines, so it can sit close to a wall. Adjustable Shoulder Airbags — Move inward and outward to sit correctly on narrow or broad frames. Arm Paddles & Rollers — Forearm compression with roller work under the palms. Triple-Action Heating Therapy — Warmth at the lumbar region, the seat and the feet. 24 Auto Programs — Twenty-four presets, from a short neck session to a full-body routine. 32-Cell Air Massage — Thirty-two airbags firing in sequence for full-body compression. Wide Seat & Shoulders — A broader shell that accommodates larger frames properly. Automatic Extending Footrest — Adjusts to your leg length so your heels land where the rollers expect them. Calf Rollers — Roller work behind the shin, not air compression alone. Foot Reflexology — Dedicated rollers under the arches. Wireless Charging — A charging pad set into the armrest. Bluetooth Speakers — Speakers in the headrest, either side of your ears.
