Have Aeron at home, worthless crap at work (Score 1)

I spent a bit of time arguing with a previous boss about how crappy the USD$400+ chairs with custom fabric were, lousy adjustments, thick foam that didn't provide any sort of support. I bought an aeron for home with most of the bells and whistles and have been very comfortable with it. To answer previous comments, take the time to adjust the chair, don't slide your butt back and forth across the mesh and it won't act like a cheesegrater. I have found that sitting incorrectly in these chairs isn't comfortable, so if you slouch or sit on your feet get some 30 dollar used office thing.
