Need a new chair

I need to find me a better office chair. For some reason I can't find one that is actually comfortable that does not have a tendency to flip backward with me. The one I have now does not do that - yet - but it is not what I would call comfortable either. It is just your standard armless secretarial chair and while it is a pretty chair, brown fabric seat and brown leather back, it is just an armless secretarial chair with no real comfort to it. Time to go chair hunting and find me a good chair.
