Canopy Stair

You don't need a treehouse to appreciate the convenience of the Canopy Stair. You just need a tall tree and a desire to access its limbs. This modular stair system, created by designers Robert McIntyre and Thor ter Kulve, uses a series of ratchet straps to attach the cast aluminum frame, treads, and handrail to the outside of the tree trunk, letting you attach more as you go until you reach the desired height. The stairs will then stay sturdily in place until your adventure is done, and disassemble as easily as they go up.
