The Osaki OS-4000 is a full function massage chair that automatically detects the natural curvature of the human body and adjusts the massage to fit. The zero gravity position elevates the legs above the heart and more evenly distributes the user's weight. The OS-4000 also fetures hip air massage, seat vibration massage, neck and shoulder air massage, air and vibration arm massage, and heat therapy for your back lumbar area. Choosing your massage is easy with the 6 unique auto programs: Healthcare, Therapy, Circulation, Relax, Smart, and Demo, all with one touch of a button. Massage combinations are endless with 6 of the most desirable techniques: Shiatsu, Swedish, Kneading, Clapping, Rolling, and Combo. Add to that 5 speed and intensity settings and you have complete control of your massage for ultimate relaxation. There is also automatic massage settings for the upper body (shoulder, neck, back and lumbar) and the lower body (buttock, thigh, calves and feet). You can manually adjust the massage for the upper body with three options: full body, partial and fixed. You can choose any of six massage styles - rolling, kneading, clapping, shiatsu, Swedish and combo.
