Gaslift for Chairs

When selecting a replacement gas lift cylinder for your office chair, "Stoke" is the term that refers to the extension part of the gas lift at full height.

The overall length of the gas lift is measured to include the gas lift parts encased in the office chair (+/- 20mm) and is expressed in the specifications as a measurement ranging from height to full extension height.

To measure the overall length of your existing gas lift, position your office or lab chair at its lowest height and measure the existing gas lift cylinder from the underside of the chair base component to the underside of the chair mechanism component. This measurement with the gas lift fully down is the minimum overall length measurement. Now lift the office chair seat to its full height where the gas lift is at its maximum extension and measure the cylinder from the same points to find the gas lift's maximum Overall length measurement.

Please Note (when measuring overall length): If the bottom of the gas lift cylinder is poking through the bottom of the chair base, the measurement should be taken from the end of this part that is poking through rather than the underside of the chair base.

*Morse Tapered Core is the size of the base core/hole. All of these gas lifts measure 50mm.
