What Made the Aeron Chair an Icon

In my experience having worked in an office which was all Aeron chairs for several months I feel no different now on this $100 office mate chair or any of similar priced chair at the various co-working places I visit. I should note too Im not exactly in great shape.
tl;dr - price and talk made the Aeron chair an icon
I added an adjustable-height keyboard tray screwed into the bottom of a desk and it will give anyone much better ergo than any chair alone.
Each time I get one, I replace it with a patio/lawn chair (+keyboard tray) and cut the legs to my height - those are actually designed to be sat in for hours. The first time my boss was a bit perturbed until I put the "extra" chair in his office.
A copy of the AIA Graphic Standards Manual[1] has charts for work tables and desks shows just how wrong not having a keyboard tray is for ergo.
