Ok first off the box was banged up and opened on both ends. This is very unsanitary to me because of bugs and other things.  The mattress is EXTREMELY heavy. There is no way that a person can do anything with this mattress without help. I do not understand why mattresses these days are so heavy. I let the mattress sit for three days and it only expanded to 11 inches. So there's that, if you do not mind an inch short. And lastly I'm not sure if I will keep this because it says firm and this thing feels plush. I'm wondering did they send me the wrong one. Kinda disappointed.
