This Sunbeam Premium XXL-Size Heating Pad with Compact Storage delivers soothing heat therapy for common muscle and joint pain. The 20 x 24-inch flexible, plush pad is 60% larger than Standard-Size Sunbeam Heating Pads, for full coverage of large muscle groups such as the entire back and legs, and can help accelerate tissue healing and relax sore muscles associated with muscle tension and stress. Customize treatment with 4 different heat settings and 2-hour auto-shutoff. After heat therapy treatment, roll up controller in 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.
