We purchased this as a Christmas gift for my 3 year old son. Being a notorious DIY guy, my wife was concerned that I would never be able to get it together let alone in a timely manner. The instructions make it easy as does the hardware. I and my dad were able to get it together in a single December day. My son absolutely loves it and has gotten hours of enjoyment and exercise from it. This is by far one of the best outdoor sets on the market.
