EC-428 'Operatinal Stool' designed by the office of Charles and Ray Eames for Herman Miller. The short production lifetime of approximately 1973-1979 makes this a rare stool indeed. It is in very good functional and cosmetic condition with the adjustable back rest intact and functioning. Age typical tarnishing of the lower base but the chrome on the seat back is in great shape. Price includes shipping, (disassembled) via UPS.
