For the price, it’s pretty functional. I can’t feel the metal bed frame through the mattress. The frame of the couch itself is plywood though. When you unpack it, the bed is tied in three spots underneath the couch so that it doesn’t fall open during transport. You have to undo those to open the bed. 

Update after 2 years the back cushions are sewn in place and have horrifically ripped away from the frame. I was able to sew them back in place, but something like this should not be happening, especially with the custom upholstery I selected.
