A polypropylene folding chair, currently in development with Jenny Wu. Functionally inspired by pop-open cardboard storage boxes who gain rigidity through folding - this too is cut from a single sheet of extruded PP sheet, which quickly folds together through beveled live hinges and slots.

Using polypropylene requires far less energy and is much less expensive than the production of a standard aluminum folding chair, and as it is all one material with no hardware it can be very easily recycled in a #5 plastic recycling stream. Additionally, as the cut material shape is perfectly rectangular, no material is wasted in its production. The chair folds to a flat rectangle less than an inch thick.
