CanopyStair, A Spiral Staircase That Straps to the Trunk of a Tree

CanopyStair is a spiral staircase that straps to the trunk of a tree. Each step is modular and can be strapped to the tree without the use of tools. The CanopyStair was designed by Robert McIntyre and Thor ter Kulve as a way to easily climb a tree, and the duo put care into the design so that it would not harm or mark the tree once removed.
