It's comfortable as a couch but the only thing I would change is the back of the couch, where you lean back to realx, if it were taller and the pillows matched the length of the back board it would have better  support on my back. It would of been a 5 star for me but unfortunately, It only covers about half of my back and my back starts to hurt after a while and I'm only 5'3, I know my height is not the issue.
I still haven't tried the sleeper part yet but it would be cool if the couch came with a removable washable cover since the cushions are on the floor when it's folded out. But it's still a good couch for it's price.
