Herman Miller Aeron Chair
Do yourself a favor and stop buying the cheap Office Club crapola office chairs that wear out and break on an annual basis, often causing bodily harm in the process.
This is a nice chair that will last a lifetime. It doesn't squeak, creak, or groan. It just sits there and looks beautiful, begging to be sat in. And when you sit, go ahead and recline and throw your feet up on the desk without fear of being instantly ejected the way cheap chairs tend to spring out from under you when leaning back. The Herman Miller is rock-solid and well-built.
