Herman Miller Size B Black Aeron Chairs

We have 10 left of these Herman Miller Aeron chairs in very good condition. It is size B, black on black, with no flaws in the mesh of any kind and very clean. This chairs has just height and seat tilt with tilt/lock, and tension control adjustments. It has just the most minor scuffs on the lower part of the backrest (which is where these chairs typically get marks) and one scratch on its base, but it looks great. We are selling it for $475.
