Setup, Compatibility & Care
To install the piston, you will first need to remove the existing gas lift from the chair base and the seat mechanism. This often requires a rubber mallet to tap the old unit out of the star base. Once removed, simply press the new piston into the 50mm hole of your chair base and attach the seat mechanism to the top. No regular maintenance is required, though you may wipe it down with a dry cloth periodically to keep it clean. Avoid using harsh chemical solvents on the cylinder, as this could damage the finish.
