Charmion, congratulations on the contract! I have a movable up/down standing desk (that I'll be using more once it's set up again). I got an "Anti-fatigue standing mat" that helps with standing more comfortably. (It's tucked away in my office closet now while my desk is in the front room, behind a wall of plastic.) When I put the office back together I'll try to be more scientific about it.
