Yes, but try out a few other chairs of similar quality first. They all have slightly different shapes and some feel better than others, depending on the person. Even in the office I use, we have several batches of Aerons with slightly different feels and features.

EDIT - Here are some other brands that usually don't carry such a price premium on CraigsList:
