Three (3) Herman Miller Aeron Size B office chairs in rough shape. These chairs are in very poor cosmetic condition. These chairs also have some mechanical issues. These chairs are for parts or for you to repair. No, I do not know what exactly is wrong with all of them, and no, I will not investigate the chairs further for you. All the information I have is in the photos and in this description. Again: the chairs are parts/not working, and they are priced accordingly.
