The spare pads are suitable for the Ant chair as well as fort he Serie 7 chair by Fritz Hansen, as both chairs have the same frame. They protect the chair and its legs as well as the ground the chairs stand on. Moreover the plastic pads reduce the noises that might be caused when the chair is moved.
The plasic pads are easily attached under the chairs' feet. The pads are available individually so that the chair doesn't have to be re-equiped completely: its single pads can be exchanged separately.
