I would recommend this pillow for anybody who uses a cpap machine as the design is very accommodating for your mask and hose. For back sleepers like myself, the cutout design for the neck is very comfortable and the right height. I also have a bad neck so this is very important to me. When I sleep on my side the design of this pillow means I don't have to wrestle with making a regular pillow accommodate my hose. Also if you have a full face mask like myself, you know you have to leave the space above your nose free so that you don't block the air you exhale. The side cut-outs are very helpful here.People using cpap know how hard it is to wrestle with a regular rectangular pillow and try to shape it so your neck is supported when you sleep on your back, and then try to flatten it when you sleep on your side. This pillow makes all that a thing of the past.I was very pleased with the quality of this pillow and the price was reasonable to me. It comes with it's own pillow case so there is no need to struggle with a regular pillow case to get a good fit. for it. . Needless to say I have used this pillow every night since I got it a few weeks ago and I give it 5 stars for all the ratings above.
