Get ready to ease where it hurts with this Conair HP15RB king-size moist heating pad. Apply heat to sore muscles and body aches for soothing relief. This pad is big enough to apply to larger body areas like the back, torso, or thigh. And the washable cloth cover feels soft against your skin. Controlled moist heat from this king-size heating pad brings temporary pain relief to muscle strains and sprains, joint pain, and inflammation. Moisture from the heated sponge pad penetrates sore muscles with its own therapeutic wet heat, increasing blood flow in the affected areas to provide relief. The king-size pad with a machine-washable cloth cover is big, making it an ideal treatment option for lower and upper back pain. Easy-to-read LCD controls let you set and monitor the temperature for the treatment that works for you.
