Please check the photos for the exact item(s) you will receive. Colors may vary slightly in person from photos. They were on a Size C chair. They work great, swivel to all 3 position. They lock in place when on the chair. The pads show some wear, however for replacements arms, they are in very nice condition. The stickers from the exact chair these came iff are in the photos as well. If you are looking for a backrest of a size C Aeron, one will be listed as well, please check our store frequently as these OEM parts typically don’t last long. If you need any other part(s) (other than the seat) you can message us. Unfortunately, this Kid/Adult (Me) cracked his seat doing super mature stuff Lol. So my new Herman Miller Aeron chair just arrived, time to provide some parts to those in need.
