I bought this to replace a smaller swing set. It took five adults about two days to assemble. Had a great "family" time while working on the new set. I purchased this set to allow my oldest grandchild (13) to play with her younger brother and cousins. The grandchildren wanted to play on it while we were doing the assembly. Had no problems with the assembly. Laid out all parts, separated the parts then assembled each section according to the instructions. The instructions were straight forward and easy to follow. Loved by all.
