Our Large Heartbeat Pillow™ was originally designed for shoulder and rotator cuff injury, but can be used on other areas such as the hips, knees, neck, and chest. Warm and place on your chest for a wonderful night's sleep... the natural solution for Insomnia! Heating in the microwave for 2-3 minutes will provide approximately 45 minutes of soothing warmth on chilly nights. Tuck down by your feet for an extra treat! Great for tummy or monthly cramps.
