My husband has been using this pillow for years with his cpap machine. He doesnt like any other pillows now. The foam has started to age and break down after many years of use. Most companys would make you buy a whole new pillow....which I was going to do. To my surprise you can buy the filling by itself and refresh your pillows contents. I was so happy that I bought a pillow for myself to try.

This filling helps me sleep easy with my CPAP mask on. The foam helps soften it and keeps the buckwheat hulls from shifting too much.
