  2. 2

    Lift the seat pan mesh slightly and take out the worn foam insert.

  3. 3

    Position the new insert so it follows the original shape and edges.

  4. 4

Aeron chair seat mesh replacement - all good

I have an Aeron side model that I don’t think is being made anymore - bent metal frame, no adjustments. The back and seat are the same framesj/mesh as the adjustable models. The seat mesh ripped - I didn’t need the whole frame, just the mesh. Found it here. Watched the installation video, took care of the situation myself. Easy ordering, good delivery time, items all in good shape.

Fits Aeron remastered Size C

I have remastered size C and they dont have size C, this still fits the size C remastered comfortably without issues. Didn't have to use the double sided tape, just slip it in between the mesh and seat frame, it won't fall off.
