Although I consider chairs in the $100 to $200 range to be mid-level, the truth is that the best office chairs extend to prices well over $1000. The major reason I consider the $100 to $200 range to be mid-level is because, as you will see in our reviews, office chairs in this range usually offer mid-level adjustability and ergonomic support.
Lumbar support, adjustable seat height and adjustable arm rests are the norm for chairs of this price range. Typically, I believe that chairs under $100 are meant for occasional use, as they are often built without any special supports or adjustable features. Chairs over $200 are meant for people with injuries and special body considerations which require a high level of customization. Office chairs in the $100 to $200 price range typically offer you enough support to sit comfortably throughout your day and enough adjustability to customize your sitting experience.
