Not sure how to rate this as a futon. It went together easily. I sorted and assessed the parts before I started and followed the written instructions. Got it put together in a couple of hours by myself. It doesn't have arms, didn't notice that in the picture and the back of the seat sits much lower then the front. Not a comfortable position for me.  I bought it to use as a bed frame, though and it worked perfectly for that. The back supports stick up enough at the ends to hold the mattress firmly in place and, with an 8 inch mattress, almost disappear.
