Talk about zero-waste design- here is a stool made of cardboard. Netherlands designer David Graas says "You not only assemble this stool yourself, but, because product and packaging are both made from cardboard, also finish it yourself. Two parts of the stool are simply cut loose from the box where the remaining six parts are packaged in. "
He also designed a cardboard chair ,
a pair of stools called This Side Up-"A cardboard box, machine cut from a single sheet of cardboard, transforms into two stools by pulling the two identically shaped stools apart."
