We tried a couple dozen chairs at various stores and this was the only one that felt good enough that I could imagine sitting in it for 8-10 hours/day. At my desk and computer, that I use for school work, I have a good but older office chair with an additional lumbar support pillow. It's tolerable at best, and I look forward to my wife going back to work so I can steal her chair.
