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.
I really tried to like these pillows but I don’t. The cover is too thick for one and the stuffing constantly bunches up on one side and makes it extremely uncomfortable and I never noticed any cooling. I ended up buying the cloud dual cooling pillows and I absolutely love those! Way better! Only pillow I will use from now on!
