It's a futon, and it's a nicer version than the cheap ones you see in someone's dorm room, but the construction requires that it sit out away from the wall because of the seat support. I gave it three stars because it's more comfortable than most futons, but the size is misleading.  I got it because I needed it for a smaller space, but the awkward back makes it sit away from the wall too far, taking up more space.
