The reason I gave it three stars, is because it can really only be used in three positions and not four.  Also, it was trying to put it together as it came with no instructions what so ever or any labels on the individual pieces, but why would it come with labels if it does not come with instructions.  You cannot use as "couch" like as no mattress fits it that way.  So you have to either use it as a bed or a lounger.
