CanopyStair: A modular system of steps that can be attached without tools to form a spiral staircase around a tree trunk

Remember when you were little and a tree-house was the most spectacular building you wanted in your backyard? An important part of the build was the way to reach the upper part. In other words, the ladder! With the device shown here you can simply strap on the tree itself a bunch of stairs. The CanopyStair is a clever tool for whenever you want to climb a tree, not just to reach your tree-house.  Some say this device is not good for the tree, in the long term. But used only occasionally, it will provide the user with an efficient way of getting to the top of a tree without much effort and permanent harm to the tree itself. Check it out in closer detail and see for yourself how easy it is to install it and climb afterwards.
