It's a lot of pieces.  And took us between 6 and 8 hours over a few days. It's super easy since everything is labeled and spelled out for you. Some of the wood cracked when putting in screws since its not very thick cedar. The wood is very light. It's a great size for our 2 and 4 year old. I even climbed in!  We were NOT missing any pieces and even had a couple extra hardware. It's good for the price but not the highest quality.
