This is the versatile cushion that delivers a soothing deep tissue massage while sitting in a chair or lying on a sofa. It uses Smartscan technology to detect a user's height up to 6' 7" and provide custom massage treatments that use heat, vibration, and Shiatsu therapy. A pair of rotating nodes target the neck, while four additional Shiatsu-style nodes move along the back to deliver a deep kneading massage. It also has a built-in air chamber that inflates to stretch the lumbar and the cushion's seat provides three levels of vibration. An attached remote controls the massage type and intensity and operates an optional heating function for additional therapy. Its plush sides and soft material ensure a comfortable surface to both lean against and lie on. Not for use with pacemakers. AC adapter. 30" L x 81/4" W x 18" D. (19 lbs.)
