Secondly, you don't rest all your weight on the steps. When taking the shot/standing sure you'll have most of your weight on a couple steps...but people OWN THEM them say that they really comfortable to "sit" in....kinda like a hammock.
When you are sitting, don't you hang against the tree? What do you do with your feet? Do you let them dangle or wrap them around the tree? Wouldn't your legs go numb from lack of blood flow? I like to be able to sit back and relax when I'm in a tree. Sometimes I put one leg up just to change position once in a while. To me it would be no different than putting on your safety harness and jumping off your stand and hanging there. If you are intent on trying this please let us know what gives. Sometimes things work different than you expect them to. I could be way off in my assumptions. These are just questions that come to my mind.
