The chair is a tool of extreme simplicity and antiquity, and many would argue that it's foolish to mess with something that obviously attained perfection with the advent of air conditioned seat cushions. Of course, those people have never seen Leopard, the high-tech "concept chair" that takes technology originally developed for Oki's Robot Leg (an entire robot with design principles based on the human leg) and places it under your posterior for "seating comfort akin to being held in someone's arms." This is a chair that adjusts itself to your back, cradles your bum, and gives you a helpful little boost when it's time to stand up. Sound wasteful? Extravagant? How about totally awesome?
