FEATURES
Zero Gravity technology
The chair reclines and lifts your legs until they are above your heart. The benefits of the zero gravity shiatsu massage chair is pressure relief for the spine, relaxation of the neck and back, less pressure on the heart, increased circulation and blood oxygen levels, and expanded lung capacity.
Body Scan technology
At the touch of a button the Osaki OS-4000 will scan your body to adjust the rollers for the perfect massage and automatically adjust the height and width of the chair to fit your body. Coupled with the S-Track massage robot, this chair is can focus on specific problem areas like the neck, shoulder, and lumbar.
46 Multilayered Air Bags
The Osaki OS-4000 has 46 air bags of various sizes that massage your entire body to further enhance the zero gravity experience. The massage technique is very close to that of the human hands, placing pressure strategically to enhance the overall massage experience. Airbags hug your body from the neck to lower back, from the arms to the calves.
Truly Ergonomic S-Track
The Osaki OS-4000 Zero Gravity Shiatsu Massage Chair is ergonomically designed to follow the natural S-curve of the human spine. It provides support to 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 tissue.
Comprehensive Human Hand-Like Massage
The zero gravity shiatsu massage chair is equipped with extra soft twin rollers to mimic the feel of the human thumb, thereby 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.
4 Unique Massage Functions
The zero gravity shiatsu massage chair features kneading, rolling, tapping, and clapping. Each functions as a push & grasp massage for maximum therapeutic effect. These massages are particularly effective for the neck and shoulders.
Remote Control

The easy-to-use controller with LCD display allows you to make changes with just the touch of a button. There’s even a convenient mini-remote. With the built-in auto timer you can adjust the massage from 5-30 minutes with an automatic shutoff when the program is complete.
