aeron.

seriously though, ikea has some pretty good chairs for the price, imo. or see if you can catch a higher end chair on sale online somewhere.

The Aeron is actually a good buy if you agree with Spolsky's math.

Next time I have a chance to buy a chair I'm going to consider the Aeron. Having to fidget every 5 minutes because the chair's not comfortable has an annoying habit of making me forget exactly what I was just doing, and the Staples/Office Depot chair du jour always seems lacking.
