Instructions were the worst. The very 1st page was incorrect. You must make sure that you read the whole page. Do not rely on just the pictures. It is helpful that the wood is all labeled. We were alarmed by the amount of hardware leftover despite following all the instructions. Very sturdy once put together. Will have to find a way to adjust the trapeze bar because it is way to low. I am not sure this would work for 10 year olds.
