Key Features Of the Osaki OS 4000 Massage Chair

Computer Body Scan Technology, with Auto Leg Scanning

This cutting-edge technique allows the massage chair to scan a user’s body shape to effectively gauge his/her body size. It then adjusts to accommodate this size and offer a personalized, custom body massage for each individual user. Special attention is paid to the user’s calves and feet where the massager is capable of adjusting to suit the user’s leg length.

Intelligent S-Track Detection Technology

The in-built S-track rolling system is vertically integrated and is designed to deliver hand-like massages for a variety of body contours and spinal shapes. The massage motion works the user’s vertebrae to ensure all stress and strain is relieved, and relaxes the body’s nerves for improved spinal posture.

2 Stage Zero Gravity Positioning

Zero gravity is a technique that ensures the user’s body weight is spread out so that the body remains almost weightless during a massage. There are 2 adjustable levels, with the fully reclined level offering users a therapeutic effect which can be felt almost immediately.

Air Cell Massage Technology

This advanced technology consists of a highly unique design, where the system covers all key body areas including shoulders, calves, feet and arms. The air cells are specially programmed to inflate separately, causing the body to twist and deep stretch, with up to 5 intensity options. The result is a quality massage that leaves the user feeling refreshed and replenished.

6 Massage Styles

The Osaki OS-4000 combines the best of all worlds to provide you with option for up to 6 therapeutic massage styles. The available options are: rolling, kneading, lapping, Shiatsu, Swedish and a combo option. The auto-programs included also offer 6 different programs: healthcare, relax, therapy, smart, circulation and demo, to cater all the demands of your tired muscles and leave them replenished.
