Very easy to assemble.  Looks cleans.    The truth is this isn't a sleeper sofa, but rather a click style futon.  The foundation is very sturdy, but the sitting/sleeping surface is incredibly hard.   We're purchased this for a houseguest and had to run out the next day for a 2" mattress foam topper so that he didn't feel like he was sleeping on a board.  Also, the removal and then replacement of the arms for sleep is very difficult;. The arms do not slide on and off easily at all.  Lastly, if the person who is sleeping on this is taller than 5'4" make sure you buy the matching ottoman as an extender.  Thankfully I did due to another reviewer's suggestion.  Without it my guests legs would have dangled big-time while sleeping at any angle.  Keeping it because I'm stuck with it and it doesn't look bad enough in the discs to warrant the expense of return.
