This is pre-owned, has runs in the mesh, shows wear that may need touch up paint, but is ready to be put to work on your chair.

This is for one Seat Mesh that fits the size B chair, and is a genuine OEM piece for the Aeron office furniture line by Herman Miller.

These are difficult to install because it seems as if it is not big enough, use clamps to lock in place all the way around before you do any screwing, then screw it in place.
