This mattress was delivered in a box. After you open the box and the plastic it just unfolds and you need to wait two days for it to fully expand before sleeping on it. ￼ because this was going in an upstairs bedroom it was really nice to have it in a box to just carry up and then open instead of trying to maneuver a large mattress up a large flight of stairs, this was really convenient. The mattress itself was extremely comfortable and I was worried that it would be hot, but it was absolutely cool to sleep on. We’re super Happy with this mattress and would definitely order it again.￼￼
