I finally bought my dream chair after years of putting it off. BTW, the prices listed are no where near reality. If you buy through the web site it's ~25% off. If you call your local HS office its significantly less than that.

As for Herman Miller. I used one in work and "for me" it was HORRIBLE. If I did not sit in the Aeron perfectly it was the most uncomfortable chair on the planet.
