If you put anything other than your head on this it will go flat as a pancake. If you sleep on your side and part of your shoulder is on it won't work. Sleep on.your stomach and part of your chest is on it - sinks down until nothing left. Is also isn't any cooler than any other pillow is. I have to constanly flip or my hair sweats. Maybe if you didn't use a case on it it would be cool but then you couldn't keep it clean. If you sleep on your back and only place the back of your head on it then it's fine.
I am impressed with this pillow so far. We received two pillows as part of a promotion, when we purchased a king mattress. It is made from a heavier material than what I am used to. It is sort of cross between memory foam and spring type foam, but definitely has more weight than a standard foam pillow. It is also infused with a lavender scent, so it doesn't have that new chemical smell that is often associated with new pillows or blankets. It will also bounce back to its original shape, even after a night of sleeping, without issue. Before getting the pillow and mattress, I was constantly plagued with soar, and kinked neck issues. Ever since we received these, I have been waking up, much more refreshed, and best of all, no more soar neck!
Is this pillow all it was claimed to be? No, it is not. I still sweat and the pillow is on the flat side. It's okay. I do not love it and would not buy another like it.
