The gas lift or gas cartridge is a mechanism that is responsible for adjusting the height of the seat surface and allows you to fix it in a convenient position for use.
The whole system is movable, you can turn on the chair, move it thanks to the rollers without getting up. The seat is height adjustable. This is done at the expense of the gas lift - perhaps the most important element. It is located between the crosspiece and the seat in the area of the chair leg. It is a hollow cylinder, inside of which there is a hydraulic spring with pumped compressed air, two valves. By adjusting the air pressure, you can raise and lower the seat.
The gas pressure in the elevator is regulated, and, accordingly, the height of the chair is adjusted by pressing the lever. If you press and release, the seat will rise, if you press and simultaneously press with your palm, it will fall.
If you sit on a chair, and it independently changes the position of the seat down, and after a while returns to its place - this is one of the signs of a gas cartridge breakdown. In this situation, you can fix the position of the chair with improvised means or replace the gas lift.
