I never believed a CPAP pillow would make a difference in my life. I decided to give it a try. I was using a well know expensive pillow that was soft a fluffy and comfy. I ordered this pillow and at first it to ok me a few days to get used to it but... my events per hour went from an average between 5-7 reach night to now 0.8 events per hour since using this pillow!!! I will not go back to my old pillow!!! What a difference!
