My husband was able to put this together by himself over a weekend, and said he was pleasantly surprised that everything came together pretty smoothly. The only complaints were that we were missing one fastener for the slide and some of the wood was already peeling and chipping. We will definitely be sealing the wood. My three year old is the perfect size for this and she will be able to enjoy it for a couple years at least. This set is definitely best for younger children.
