Assembly instructions were very clear.  It does take 2 people.  
The quality of both the frame and mattress are very good. Mattress is very nice to use as a guest bed. We love the colors of both frame and mattress.
The only downside is you can't sit straight up as a sofa.  The back slants quite a bit in the upright position.  Short legs don't quite reach the floor.  I will try some throw pillows for back support.
