Herman Miller OEM seat mesh. No rips or tears on mesh. Aeron mesh installation often requires the use of additional tools (C-Clamps to hold it in place for instance) or the assistance of an additional individual. Aeron meshes will appear to be too small – this is because then are tight fitting when installed. A big of guidance: please remove the banana shaped support cushion, attached to the seat pan, prior to installing a replacement mesh. Be certain to clean the seat pan – including the seat mesh frame canal, prior to installing a new mesh prior to installing.
