I really like this mattress. I have a original king memory foam in my master bedroom, which I always loved, except for hot summer. This queen mattress is memory foam, but has a built in texture top that air can cool and circulate. I slept in it all summer! Except when kids/family used this guest room. I have a twin bed guestroom, I would like to replace those mattresses with this one if possible. Came rolled up, waited 24hrs before installing in bed frame, new mattress smell dissipated in a week or so-- cracked the window to help.
