>Move everyone to standing desks and cut out the costs of chairs. I'm not joking. I've been using one for over a year and I can't bear to sit for long periods of time at work any more.

Standing up for a long time is not good either. The key idea here is change. Stand up, sit down, move around.

I ran out and picked up 4 plastic crates, 1 for each corner if the desk. Presto - perfect height standing desk. For a chair I use a slightly used bar chair (the kind you use for kitchen breakfast bars) - but after 1 month I don't feel the deep thought and focus I would get when plunked in a chair.
