🛡️ 5-Year Premium Warranty Included

An AI-assisted dual-track chair that reads your body's condition through a handheld health sensor, then builds a massage program around it — with a quieter mechanism and a slimmer touchscreen than earlier Osaki models.

Intelligent AI Health Monitor: An armrest sensor that reads heart rate, blood oxygen, microcirculation, HRV and fatigue to personalize the session.
4D+3D Dual Mechanism: A 4D system for the back paired with a 3D air system for the glutes and hamstrings.
Smart Body Scan: Adapts the massage path to your specific body contours automatically.
SL-Track: Continuous coverage from the neck through the glutes to the top of the hamstrings.
Quiet Massage Technology: Noise-reduction engineering for a near-silent session.
26-Cell Air Massage & Carbon-Fiber Heating: Airbag compression plus heat therapy across the lumbar, seat and calves.
Auto-Extension Footrest: Extends up to 10 inches to fit users up to about 6'4".
Thinner 7" Touchscreen: A slimmer, easier-to-navigate remote controller with a modern finish.
