The Aeron is not about looks. Those are just a side benefit. Most people find to be one really comfortable chair (and for 2x the price of a good (not the 50 dollar office max special) it better be). Other chairs might be as good (or better) but they haven't been tested by my ass for long periods of times
. Herman miller has a new chair (mira?) that supposed is pretty good but I haven't sat in one foran 8 hours day.
