Janus chair is a prototype designed by a Los Angeles industrial designer, Jang Yoon. At first glance it looks like a futuristic stool, at second glance it’s more than a stool. When someone folds up the seat, Janus chair comes to life! It was exhibited at the International Contemporary Furniture Fair in 2009. No word yet on whether the chair will make it into mass-production.
