I was wondering if anyone here can recommend a good task chair designed for long hours of sitting. I have an inflamed muscle in my neck and am looking for ways to be more comfortable in front of the computer. Due to the nature of my work, I am forced to sit for long periods of time, although I do make it a point to get up and walk around at least for a few minutes every hour or so. Anyhow, I'm looking for a comfortable chair that I'm assuming should be ergonomic. Any recommendations would be highly appreciated.
