Ryan Horsman and Jason Dembski created the Chopstick/Steamer Stool as part of their summer abroad program at B.A.S.E. Beijing. The stool is made completely of chopsticks and bamboo steamers, which can be found in every household in China.
Note there's a hidden cushion in the middle to give the seat enough give to be comfortable. It's that kind of thoughtful design detail that makes all the difference.
