Whether you're building a treehouse or looking for a way up to a large branch, CanopyStair will get you there. Designers Robert McIntyre and Thor ter Kulve created the modular system of steps that can be attached without using tools or hammering into the tree. They form a spiral path around the trunk, allowing you to ascend from the base to the top with great ease.
CanopyStair is lightweight and quick-to-assemble product, consisting of a cast aluminum tripod frame, rubberized tread, ash-wood handrail, and ratchet straps that fasten the staircase into place. The designers curved the shape of the steps to help them appear straight, even if they have to be installed at an uneven angle. “As one climbs the steps, the slight curve on the top surface of the tread acts to ‘cradle' your foot, adding to the sense of security,” Ter Kulve told Dezeen.
Thanks to the adjustable straps, CanopyStair can be snugly fitted on a variety of trunk girths. Its installation time will vary depending on how high you want the staircase to reach. According to Ter Kulve, scaling a 22-foot tree would require about three hours work with two people. However, taking it down could be done in just 30 minutes.
