I test furniture for a living. Mainly deal with structural testing but I'm also used for ergonomics evaluations.

No kidding? Then I guess you are the man to talk to.

I'm okay with the Aeron in the largest size but I prefer a KAB Seating chair for the upper back support. Desk height and monitor & keyboard placement are critical. For the current chair I'm sitting on I have my desk 30 mm higher then with my normal chair.

I was thinking about the Aeron also, but that mesh doesn't look that comfortable to me. Reminds me of lawn furniture. That's why I was thinking about the Bodybilt, with the memory foam. Actually I have a Tempur-Pedic bed that I find very comfortable. I have yet to sit in either the Aeron or Bodybilt though.
I'm average size, 5'11" 190lbs. My current chair is 16" high. My keyboard is 26", and the top of my monitor is 4'. So when I'm sitting, back straight, my eyes are level with the top of my monitor, and my keyboard is about the height of my elbows. I spend all of my time seated (10+ hrs a day), typing and using the mouse.

Our Ergonomics Unit has me sitting in loads of different chairs and they computer pressure map me in them because I'm tall and fat - 99% of the UK population are short and weigh less than I do. The Ergonomics Unit can monitor me remotely and see how I sit whilst working. I sat in a proto-type chair the other day with the best back I've ever felt. They are making me a better seat and head rest for it. If you free-float in the chair then the spring tension is important. Most chairs can not be adjusted for larger people.
I've visited Herman Miller in the UK - Very impressive. I don't like their latest chair though. I'm too big for it.
The fabric and foam make a difference when you spend a lot of time in your chair.

I'm not sure what type of fabric either. Whatever is the most comfortable.

No matter how well they do on test I seem to be able to break pretty much every chair I sit on. 750,000 cycles on a fatigue machine and I break it in two weeks!
I'll ask the Ergo Unit to suggest some chairs for you.
