This Sunbeam? Premium King-Size Heating Pad with Compact Storage delivers fast, soothing heat therapy for common muscle pain and joint pain. The 12 x 24-inch flexible, plush pad is extra long for more coverage on large muscle groups to help accelerate tissue healing and relax sore muscles associated with muscle tension and stress. Feel the heat in seconds, and customize treatment with 4 heat settings and 2-hour auto-shutoff. After heat therapy treatment, roll up the controller in the pad and secure in place with elastic straps for neat storage. Enjoy convenient features, such as an easy-to-use push-button controller with LED heat-setting lights for visibility in the dark and a long, 9-foot cord. For optional moist heat therapy, spray fabric with water for deep, penetrating pain relief. The entire flexible, plush hot pad is fully machine-washable for easy care; just disconnect the controller.
