Designed by Garet Miller, this chair is made from 100% corrugated cardboard. No, it is not a sculpture for home decor, but a functional chair that you can definitely sit on. The goal was to create a chair that could hold multiple weights up to 300 pounds. It is built from 1/8 inch thick, 4×8 sheet of corrugated cardboard. He has designed this chair in such a way that it can be put together by folding and assembling only three pats. This chair is definitely a lightweight champion to watch out for.
