Great sturdy futon!  Couple issues that really bring it down that 1 star (or more) - it's not a wall hugger, so no matter what it will bang into your wall as you fold it up or down.  I've got a nice deep 1/2" + gouge in mine.  The mattress doesn't stay put, no matter what, in either position.  It's not like a slick wiggly worm, but it gets annoying.  We decided to just keep it folded in most cases, and rarely flipped it down so would pull it way out when we did.
