My office chair arm broke.
Various office chair arms brake due to the nature of the hard plastic. It is the last component you would think break, but it does. The cause of this is most people press down hard on the arms as they go to sit down. This causes unnecessary force onto the arms and they snap in half. Depending on the arm that is currently on the chair it can sometimes be replaced with a stronger metal arm with rubber armrest, if not we should have a range of replacement arms available in our online shop.
