My husband has ALS (Lou Gehrigs disease). He spends his time either in bed or in his motorized wheelchair. His pillow is very important to him - once we position him in his bed, he is not able to move or even shift position. Also, he sweats a great deal , and some pillows just become an uncomfortable , soaking mess. He really loves this pillow! He is comfortable on it for up to 12 hours straight, winter AND summer. It has been more than worth it's price.
