I have to agree
Love the look or hate it, the Aeron is a very comfotable chair for long duration sit-a-thons. I have NEVER had a chair that I find to be as comfortable to work in than that chair. It kind of looks like a high performance sports sneaker to me, but I don't care, my lower spine still loves me at the end of the day.
Eames
Eames Aluminum group can be had for about 500 on Ebay, cheaper on Craigslist at times. I very much like the Saarinen Executive chair on the caster base.
