The climber came in two very large boxes, but they weren't too heavy.  It was easy to lay out all of the pieces and hardware.  Assembly took about 3 hours with no major issues.  Our son, who is 2, "helped" us combine all the sections then went right to the slides when it was finished.  He'll play on it for 15-30 minutes then move onto something, but that's how most 2 year olds are right now.  It's nice to have something in the yard to play with outside and it's great for having other friends over.  The climber is pretty sturdy and a nice size.  Hopefully he gets 2 summers out of if before he gets too big.  He is already just about at the height of the openings to the sections so he'll have to duck into it soon.  We haven't had it long enough to comment on it's durability but it doesn't look like it will be a problem.
