Turn a backyard tree into the perfect hangout spot using the tree trunk spiral staircase. This railed staircase wraps around the trunk without damaging the tree, making it a safe to climb and eco-friendly way to ascend to your treehouse.

These CanopyStair is a modular system of steps that can be attached without tools to form a spiral staircase around a tree trunk, allowing one to walk up into the canopy above. Lightweight and quick to assemble, the CanopyStair has been carefully designed not to damage or mark the tree in any way.

The CanopyStair comprises a cast aluminum tripod frame, lightweight tread, handrail, and a ratchet strap that quickly fastens the step into place. The step design draws on the techniques of aeronautical engineering.
