Think of Canopy Stair by Robert McIntyre and Thor ter Kulve as a modular spiral staircase system that can be strapped onto any tree trunk, without using special tools.

“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.

However, taking it down could be done in just 30 minutes,” says My Modern Met.
