US Patent 7413254 Quick-assembly stool

A portable, easily assembled and disassembled three-legged stool or stool kit includes a seat with a quick-release leg-fastening assembly, three legs having keyhole slots to engage with the quick-release leg-fastening assembly, and a substantially planar leg bracket oriented below and parallel with the seat that has three symmetrically-oriented elongated slots to receive and orient the legs. At least one of the legs has multiple, spaced-apart sets of opposing grooves for supporting a removable, cantilevered platform such as a footrest or a drink holder. When assembled, the legs are oriented in a structurally strong and rigid fashion to support the seat.
