Meet the Verte' from Anthro. From the back, it looks like something HR Gieger would create. Only it won't frieghten co-workers (that may be a drawback), and is likely is incredibly comfortable. I've been searching for the perfect office chair since I was 17, and this may be it. At $1500 (or only one penny with purchase of a $12,000 desk), it's going to take a while to save enough money.
Anthro's headquarters are nearby though, maybe if I stand outside begging, they'll give me a discount.
