I have a hard time finding a pillow that suits 2 medical problems-CPAP mask friendly and a bad neck that requires a thinner pillow. This fit my needs perfectly. I sleep on my side and the shape of the pillow allows my CPAP mask to fit on the edge so it doesn't get pushed out of place. Now I don't spend half the night wrestling with my pillow. The only reason I didn't give it 5 stars is because of the filling in the pillow. It's not going to be long before it starts shifting around. I'll just refill it when that happns.
