pluses for this mattress- very comfortable, very nice to sleep on, sheets stay on well and dont pop off at the corners, and it is very warm to sleep on.  Minuses-only one little thing, I am a very small person, 5'0 and 99 lbs and no matter where I sit or lay, the mattress curves in towards me, and anything I have on the bed (remote, phone, etc) rolls towards me, which I find very annoying
