Got this for my daughter, who has a twisted spine due to a bone disease and is in alot of pain especially in her lower back. It is ideal!! it comes folded in half so when you see the picture its actually twice the size, its not over stuffed or too under stuffed either. You heat it in the microwave or cool in the freezer and its ready to use. Its about 14 inches long so ideal to put across your lower back, or across your abdomen if you suffer with period pains or wrap it around a joint or muscle, very impressed! She's only had it a couple of days and already feels the benefit!! Its also made of fleece so nice and soft and smells lovely. (lavender) Well worth the money and it only took a day to arrive!
