The most ergonomically-friendly way to work is standing up and the Herman Miller Envelop desk promotes this fact. Of course, not everyone can stand for spans of eight hours or more, so the desk actually offers three different positions that offer healthier work positions.
The Herman Miller Envelop desk is electrically height adjustable so that you can switch from standing to sitting positions in a cinch. Priced at $3,000, I'm sure it'll be a while until we see these in offices.
