Hon are the best, by a wide margin. http://www.staples.com/office/suppl...7_Business_Supplies_2_10051_SC2:CG32:CL142567
You don't have to pay that much for a Hon; you can get one for as little as $375. My favorite one is about $480. They last forever, and blow any other chair away in terms of comfort and quality. Make sure you go with the solid wood arms (Cherry or Mahagony).
has anybody tried one of these? my local chair dealer was a herman miller dealer but gave it up and is selling these because he says they are better and cheaper. i sat in one and it felt good. it looks just like an aerons only it has a headrest and the front of the lower cushion is padded. you can buy one for around $600 shipped.
