Osaki OS-4000 Features

Osaki OS-4000 S-Track

Truly Ergonomic S-Track

The Osaki OS-4000 Zero Gravity Massage Chair is ergonomically designed to follow the natural S-curve of the human spine. It supports both your neck and back, especially the lumbar area. This position increases the effects of massage as it enables each disc of our spine to individually separate and decompress, allowing nutrients to enter disc tissues.

Osaki OS-4000 Quad Style Rollers

Quad Style Roller

The Osaki OS-4000 massage chair is equipped with extra soft quad-style rollers to mimic the human thumb’s feel, enhancing the massage experience. The width of the rollers can be adjusted to medium or narrow mode to suit individual needs for better penetrating effects. The rolling manipulation helps dredge the main meridians on the back, acanthus, forehead, and the top of the head, along which the acupuncture points are distributed, to clear the collateral channels.
