In one of several attempts to ward off back pain, I have (hopefully) improved my office enviroment. First, I got a new chair, supposedly good for your back. I'm told this is the Korean equivalent to the Herman Miller chair, called Duoback.
Ironically, I probably sprained a couple back muscles wrestling this chair out of the shipping carton. And a few more while laying on the floor balancing the heavy chair above my head while trying to line it up with the rolling base (which rolls VERY easily, even when you don't want it to!)
Once the chair was operational, I realized that I was still hunched over, because of the height of my laptop screens. Whereupon I elevated my laptop to eye level with a lap top "stand", and elevated my auxiliary LCD display with a box.
Now I have no excuse for poor posture (he types while straightening his back from the slouching position).
EDIT - interesting quote from the Herman Miller website - "Zero is Hero. We won't stop until we've achieved nothing." Not quite sure what to make of this...
