This is an amazing play structure. My kids have been on it nonstop since my husband and I put it together. The last step was a little hard to do, the set screws weren't alligning well with the base poles it was very very difficult to screw them in without having them sticking out, but once we had it put together we were very happy with it. And so are my boys! (6yrs and 3yrs). Overall extremly happy and would highly recommend this play structure!
