Very comfortable chair as well as adjustable. If you know anything about Herman Miller then you most likely know about the Aeron. The chair has been lightly used (a couple hours at a time, a few days a week). This chair has been well kept and maintained. Overall I loved this chair but upgraded. This thing should and will be the workhorse of whatever business wether that be at the office, working from home, or a start-up, etc. This chair will get you through hours of work no problem. Half paid by me and half paid by you.
