Osaki OS-4000 Massage Chair

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.

Osaki OS-4000 Body Scan Technology

Body Scan Technology

At the touch of a button, the Osaki OS-4000 will scan your body and not only automatically adjust the rollers for the perfect massage but also automatically adjust the height and width of the chair to fit your body. Coupled with the S-Track Massage robot, this Osaki OS-4000 is capable of focusing on problem areas of the body like the neck, shoulder, and lumbar regions customizing and enhancing the massage experience.

Osaki OS-4000 Zero Gravity

Zero Gravity Technology

The zero-gravity features on the Osaki OS-4000 are notable because it is so effective and touts many benefits. Put the chair reclined and lift your legs until you are in complete weightlessness. As you can imagine, your body is completely relaxed, and in this position, you gain numerous health benefits such as pressure relief from the spine, relaxation of the neck and back, less pressure on the heart, increased circulation and blood oxygen levels, and expanded lung capacity.

Osaki OS-4000 Air Massage

Next Generation Air Massage

The Osaki OS-4000 massage chair has 38 re-engineered with the next generation of air massage technology.
