Truly Ergonomic S-Track

The Osaki OS-4000T Zero Gravity Massage Chair aligns with the natural S-curve of the spine, providing comprehensive support for the neck, back, and lumbar regions.

The roller width can be adjusted to medium or narrow modes, catering to specific penetration needs for a deeper effect. The rolling motion targets main meridians on the back, acanthus, forehead, and head’s top, clearing acupuncture points along these pathways.

Osaki OS-4000T Body Scan Technology

Body Scan Technology

With the press of a button, the Osaki OS-4000T scans your body, automatically calibrating rollers for an ideal massage experience. This technology also adapts the chair’s height and width to match your body. Coupled with the S-Track Massage robot, the OS-4000T targets problem areas like the neck, shoulders, and lumbar region, enhancing and personalizing the massage.

Zero Gravity Technology

The zero-gravity feature in the Osaki OS-4000T is remarkable for its effectiveness and numerous benefits. As the chair reclines and elevates legs, a sense of complete weightlessness is achieved.
