Meet the CanopyStair: a modular system that you can attach to form a spiral staircase around a tree. Designed by Robert McIntyre and Thor ter Kulve, the CanopyStair allows you to climb a tree with less effort. It has a cast aluminum tripod frame, tread, handrail, and a ratchet strap.
As the designers explain, the system is easy to put together to help you and your friends get a better view. What do you think? How would you improve upon this idea?
