Eero Saarinen's Executive Chair takes ergonomics very seriously. This version, upholstered, with arms, and with wooden legs as opposed to metal, in my humble opinion, is the most elegant and stately of all the iterations. Remember, there's no rule that says you have to upholster the back and the seat in the same fabric.
