Step-by-Step Instructions

  1. Remove the Gaslift:

    The first step is to remove the gaslift from the seat. We strongly recommend using our Unblocking Tool for this process. For further details, see our guide on How to Remove the Gaslift from Your HAG Chair.

  2. Detach the Backrest:

    Next, remove the backrest from the seat by untightening the bolt that secures it.

  3. Remove the Seat Mechanism:

    Place the disassembly tool between the seat and the seat mechanism. Push the tool all the way in, then press down the lever that adjusts the seat depth. Gently pull the seating mechanism toward you to release it.

  4. Install the New Seat Mechanism:

    Once the old mechanism is removed, install the new one. Again, press down the seat depth lever while aligning the new mechanism into place. Note that the disassembly tool is not needed for this step.

  5. Reassemble:

    Finally, reattach the backrest and reinstall the gaslift. Your chair is now ready for use.
