The HoMedics MCS‐840HA Shiatsu Elite Massage Cushion with Heat gives you a deep kneading back massage that travels up and down your back, relaxing your tense muscles. Neck and shoulder massage melts away tension, adjusts to your perfect height and reverses massage direction just like the hands of a masseur. Two Massage Styles: Kneading for a deep massage, and rolling. Three Massage Zones allow you to concentrate relaxation on your upper or lower back, or massage your entire back. Soothing heat comforts your tired muscles. Programmed controller for ease of use. Integrated Strapping System fits most chairs.
