The massager can be set to rotate forwards (with or without heat) or backwards using a single button. Ideal for use in home, at the office, or while traveling, the massager’s unique shape contours around the neck, shoulders, back, thighs, or calves. A faux leather flap dampens the intensity of the massage nodes and an elastic strap secures the massager to a chair. Shuts off automatically after each 15-minute session. Spot clean. A three-hour charge using the included AC adapter provides one to two hours of power. 14 3/4" L x 8 1/4" W x 5 1/3" D. (3 1/4 lbs.)
