With quick-adjust support straps for convenient sizing, reinforced corners and edges, and an exterior pocket. Its rechargeable battery provides up to five hours of heat or two hours of heat and massage from a 2-3-hour charge with the included AC adapter. Supports up to 250 lbs. 13" L x 15" W x 1 3/4" D.
