This one is a 23' home-built made out of 1 1/2" tubing, and it is HEAVY. Once it is up it is very comfy and solid as a rock, but it is so hard to move it only gets moved once in the summer. This year I brought a friend of mine (here is where you find out who your friends really are) and both of our boys. I put the feet about where they were supposed to go and had the boys stand on the bottom rung which is against the ground. Me and my buddy got on the platform end and both of us just walked it up together, wasn't too bad. The weight on the bottom rung keeps it from trying to flip as you walk it up. As long as they are about 15' they aren't too bad, but once they get 20'+ they turn into a PITA. The standing rule is, if it starts to fall just run away as fast as you can, don't try to stop it, it ain't worth getting hurt over. This one is solid enough it won't break,I don't have a problem with justletting it go.
