What is a computer chair cylinder?

The air pressure in the computer chair cylinder is mainly controlled by the chair cylinder, which is mainly composed of upper and lower end covers, piston rods, pistons and cylinder tubes. Manufacturers will fill a certain amount of gas into the cylinder when making chairs. Theoretically, cylinders should be filled with inert gas, such as nitrogen. When the human body sits on the chair, the piston will exert a certain pressure through the piston rod, and then the piston will exert pressure on the gas in the cylinder. When the gas is compressed by pressure, the height of the chair will drop, and vice versa. Mainly used for office and the like.
