32 Cell Full Body Air Massage
The Laser-Crafted Steel L-Track allows the encyclopedic massage rollers to seamlessly reach the periphery of your body, all the way from your hamstrings to your neck and shoulders.
3D Surround Sound Audio
Connect your phone to the 4000XT via Bluetooth to fully control the spatial audio accompanying your massage. Listen to your favorite tracks, audio books, murder mystery podcasts, or ASMR in genuine high-fidelity 3D audio.
Tension Sensor
The verge of massage technology means locating specific fields of higher tension without being intrusive or obstructive. As such, Osaki has developed a tension sensor to discreetly locate problem areas and handle them accordingly.
Zero Gravity Reclining
Experience relaxation in a state of weightlessness with the 4000XT’s two stage zero gravity reclining. This boundary-breaking technology was originally developed by NASA, and has now been adapted to provide a truly thoroughgoing massage experience.
Lumbar Heating
Relinquish unwanted tension with the OS-4000XT’s lumbar heating system. These dual infrared heating coils effectively warm and soothe aches and pains along the spine while improving overall circulation and health.
