The Strap chair started out as a sketch that went viral online after many people debated it's feasibility, prompting me to build the prototype. The chair uses several ratchet straps to tighten four legs to a wooden block. Any sufficient material could be used as the legs. I built the prototype in January when NYC was littered with discarded Christmas trees. I trimmed the trees and used the logs for my design. The chair has been exhibited several times and is surprisingly comfortable with the flexible straps as the back support.
