Meant to be a social project and not just a product, the Zaishu stool by Matthew Butler, uses participatory design to bring people of many cultures together. The idea behind the stool was one of creativity, participation, & sustainability. Zaishu can function as a stool, storage box or small table. Made from plywood "ideally salvaged from construction sites," the seats slot together with 5 pieces without the need of any tools. Artists and designersfrom Australia, Italy, Japan, & Korea have collaborated with Matthew to produce the artwork or patterns which are printed on the laser cut panels. The company guarantees that a tree will be planted for each chair sold- $270 which includes delivery.
