There's a chain called "The Healthy Back Store" and that's where I went to try out chairs. I ended up buying the Nightingale CXO chair, which I hadn't heard of until I went there. They also have a good online store -- http://www.healthyback.com http://www.healthyback.com -- but obviously that's not a great place to try out chairs.
