This is the back massager that provides the tension-relieving kneading of a therapist's feet during a Thai massage. Two 4"-long x 2"-wide massaging "feet" travel up and down either side of the back - their convex shape simulate the balls of a therapist's feet as they roll and knead tense, sore muscles. The massager can target the upper, lower, or entire back, the "feet" have built-in heating elements, and the seat includes a three-speed vibrating motor that can be used with or without back massage - all controlled from a tethered remote. A padded flap provides additional cushioning during a back massage; flips over and behind a seat back for a deeper massage. The massager secures to a seat back with an elastic hook-and-loop fastener. Shuts off automatically after 15 minutes. Plugs into AC with the included adapter. 27" H x 18" W x 18 1/2" D. (9 lbs.)
