I only gave this 4 stars simply because we were missing a part and one of the pieces was broken which was a inconvenience. I called kidcraft and they replaced the broken piece and sent the piece I was missing super fast. Overall it was fairly easy putting it together. My mother in law did 90% by herself in a weekend. You will definitely need two people for the tube slide but it wasnt difficult just time consuming. My daughter absolutely loves it and I would definitely recommend.
