The other reviewers hit the nail on the head with this one.  I bought this for our art studio/playroom/guestroom and have found the kids LOVE it, it's a stage, a bed, a couch, endlessly manipulated by them.  I am thrilled at how easy it will be to clean as the cover unzips easily and is machine washable. But when my mom slept over she found the mattress "somewhat hard" and said if she rolled over in the night her elbow got stuck into the small gaps between the footrests/couch back.  I am planning on getting a eggcrate topper which I think will fix that issue.  Also it is very low, but that makes it great for kids.
