I like that I can’t feel my wife get into bed. I’m a very light sleeper! One night I kept waiting to hear her get in bed and I never even knew she was next to me, I passed out without knowing. She likes it because it’s firm but I am having some trouble adjusting to it as I came from a very plush bed. I also sleep very hot and now I find myself sleeping on top of the covers with a blanket because it’s still too hot for me. Without sheets or blankets it’s very cool and soft but it wouldn’t be good to sleep on it like that because it would probably get dirty. I give it 4 star because it’s not as cool as I would like. After owning 2 memory foam beds who advertise “cool” , I would have to say that either 1) they don’t work 2) I sleep very hot compared to the average person
