Does not work for me
I am a side sleeper. These ear cavities in the foam pillow are on the very edge of each side of the pillow. This makes it fairly awkward to use, layout wise. You're either in the center of the bed or hanging on the edge.
It also had a chemical smell I didn't care for, which took a number of days to degas.
Most importantly, it didn't affect the light snoring I occasionally do (wife noticed no difference) which was the main reason I made the purchase.
If you sleep on your back it may work just right for you. If you ONLY sleep on the side, hopefully you'll have better luck.
