My husband and father in law put the McKinley play-set together in about 7hrs from start to finish and a quick break for lunch. We agreed with a previous poster about having your own tools. They had to make a couple of adjustments on the fly but the instructions were easy to follow. It’s a great compact play set with just enough to do for my 4 and 1 year old. We added the bucket baby swing to ours. Very pleased with our purchase and highly recommend.
