Feels okay when falling asleep but woke me up in the middle of the night packed down feeling like a brick. Gave it a few tries and can't get it be comfortable at all. Would take any regular pillow over this thing any day.
Within 10 minutes the pillow is flat. Not happy w purchase. I will say the coolness is the best feature. I will not sleep on it again and my partner feels the same way.
I love this pillow but I am a side sleeper. Since I started using it a few weeks ago, I haven't had any neck pain and have slept great. My husband did not like it but he is a stomach sleeper.
