The mattress came roled up in a box but once it's out and left for a couple of days to fill out and form it's shape it's a lovely mattress. The sides are a bit soft to sit on so no support much but when lying on it its lovely and comfortable. It has a feel an memory foam top but does not get hot. It's fairly heavy in weight and it came with no removable cover like in pictures but I use a mattress protector anyway. I  bought it for my 7 year old daughter and she's very happy with it after a week.
