I assembled this myself, and it was not a problem.  The lounger is very comfortable once you're in it.  I am pretty agile, but someone who is not, might have trouble getting in and out of it.  You have to tilt the toe end down and kind of climb in or out.  Also, the pillow, which is attached with velcro, is useless.  It is way above my head (and I'm 5'6").  The lounger is not really comfortable without a pillow if you are reading, so I drag out a throw pillow from inside the house, which is not convenient.
