How is this chair, with only one of its leg on the floor, not falling over already? Hell, how can this guy stand on this thing! Is it a camera trick? Nope, just clever design.
Peter Bristol, the guy who made it, explains:
A plate concealed by a thick carpet allows a robust cantilevered seat. Three well placed leg "stumps" and the chair looks as though it has just been magically sliced apart.
