I am so glad I decided to purchase this product. I decided to buy 2, one for my parents and one for myself, and I cant even explain how wonderful it makes me sleep. I used to have a hard time falling asleep, not anymore! LOVE IT! It fits my bed perfectly and actually helps keep my sheet on. My father has a BAD back and it has helped him sleep tremendously. If you are reading this, STOP, and go buy it!!!
