I bought this CPAP Pillow a while back and I was so excited I even got my friend to buy 1 too. What a disappointment! It gave me more pain in my neck and back than I started out with. My friend asked me why I tried to kill him. I originally thought it was just me having an issue with this pillow but when he confirmed how it messed up his neck I threw that CRAP Pillow in the garbage and never looked back.
