Very nice glider, excellent price.  There were supposed to be four large washers to attach the frame, but only three were included.  Since there were extras of the smaller washers, we used one of those for the last piece and it seems to work fine.  It is a two-person job if you don't want to take longer than necessary.  My neighbor put it together, and I assisted by holding one side level while he attached the other side.  He completed the job is just under one hour.
