I've tried many chairs but none of the expensive ones (except for briefly sitting in an Aeron, which I liked). The last chair I bought was a $99 chair from Office Max, similar to this one: http://www.officemax.com/office-furniture/chairs/product-prod3300088 http://www.officemax.com/office-furniture/chairs/product-pro... It is the best chair I've ever used even though it is low-backed and doesn't tilt. It forces me into a good posture and is comfortable for many hours.
