The renovation story

High-end task chairs get dumped for one reason: the gas cylinder gives up and the mesh sags. Both are €60 of parts and about ninety minutes of work. I bought this one from an office clearance, swapped the cylinder and seat mesh, deep-cleaned the arms, and relisted it with the original spec sheet.

DIY guide

  1. 1

    Diagnose the drop

    If the seat sinks under weight, it is always the cylinder — not the chair.

  2. 2

    Knock out the cylinder

    Tip the chair, tap the base loose with a mallet, and pull the old cylinder free.

  3. 3

    Fit new mesh

    Unclip the old seat panel, stretch the replacement over the frame and re-clip corner to corner.

  4. 4

    Deep clean

    Upholstery foam on the arms and back, then a microfibre wipe-down of every plastic surface.

  5. 5

    List with the spec sheet

    Attaching the original manufacturer spec adds real money to a refurbished chair.
