When received this was scary.....they were vacuum pack and when i open it there were folds making it much shorter. I couldn't imagine it coming back in shape. So I pull on it to stretch them ..it helped...than left them overnight and they started taking their shape. So don't be surprise you have to work them a bit to get the wrinkles out and within a couple of days they will take their shape. My grandchildren said the beds were so comfortable, they both had a great night sleep.
