Installation wasn't too cumbersome (although not the 15 minutes claimed on the instruction sheet).  Took us about 2 hours at a leisurely pace.  Like others, the full size mattress isn't a perfect fit for the full size panel bed (a few inches on each side of empty space with a regular full size mattress).  When you get a box mattress, avoid my mistake of getting a normal sized one. You will need to get something that is less than 9" (something around 4-5") so end up with a too-high bed and a comforter that can't cover the box.
