A Gauze lift Stool has springs that consist of cylinders extremely as pistons that slide in and gone of them. The cylinders subsume pressurized nitrogen and oil, according to ExplainThatStuff.com.
How Gas Springs Work
Pushing the down lever of the Stool forces the piston into the cylinder, compressing the Gauze and lowering the seat. Pushing the up lever pulls elsewhere the piston, allowing the compressed nitrogen to expand, thus raising the seat.
Vertically mounted gas springs work more efficiently and are less likely to break down at full extension. Tight seals around the piston prevent the nitrogen and oil from escaping.
They are also smaller than metal springs.
Additional Facts
Gas springs come in different designs and configurations.
