Since my wife was out of town for a few days and did not take her Kakar Pillow with her, I decided to try it. My experience with the Kakar Pillow is that I do not awaken during the night, have more restful sleep, and am more refreshed in the morning. The Kakar pillow is the most comfortable and best supportive pillow I have ever experienced. My BiPAP mask stays on better (perhaps I'm not tossing and turning?) whether I'm sleeping on my back or my side. After my experience I bought one for myself. I love my Kakar pillow and recommend it to others.
