An Open Source Chair made of Plywood and a Ratchet Strap
Beautiful project spotted on instructable that shows how clever can open designers be:
This chair is made from a 1/2 sheet of plywood, uses no glue or fasteners, and is held together by a single ratchet strap. I made this chair because I was interested in the forces at play to make a chair stand up: the different parts in tension and compression that make up the structure. It’s also part of a broader study I’m up to experimenting with ergonomics- trying variations on the dimensions and posture of Mies van der Rohe’s Barcelona Pavillion Chair (1929).
