At the risk of sounding trendy: Mostly stand, then it hardly matters what kind of chair you have; and (at least in my case) the result is improved productivity and feeling better. http://kylecordes.com/2010/standing-desk http://kylecordes.com/2010/standing-desk More on-topic: I sat on an Aeron a few jobs ago, and really liked it. I've compared an Aeron side-by-side with several "clones" and found the real thing is a lot better. If you are going to sit all day, an Aeron is a good default choice. As other posted pointed out, over the life of the chair the cost is really low.
