I took it for a test swing and my 230 pound ass was swinging like a 2nd grader (leaving the swing at the highest point) and the swing set never moved. Not even a creak lol. I would like to sure up the tall tower a bit more, it could be a little more stiff. It's not going anywhere and it's very safe the way it is, but when someone over 150 pounds goes down the slide I can see if move about an inch when they hit the first curve.
