Office Chair Cylinder
The professional name for the cylinder under an office chair is a gas lift, and it is also commonly referred to as a chair post or foot post, with core functions of lifting and supporting.
Professional Name and Core Functions
The vertically adjustable cylindrical component under a computer chair (office chair) is professionally called a gas lift. Its core function is to achieve the lifting and lowering of the chair by compressing or releasing the high-pressure nitrogen gas inside. When a user sits on the chair and operates the control lever on the chair, the nitrogen gas in the gas lift is compressed or released, allowing the chair to stop steadily at the desired height, meeting the needs of users of different heights or for different usage scenarios regarding chair height. Some advanced models of cylinders also have knobs that can adjust the tightness of the chair back's recline. Users can adjust the resistance of the chair back's backward tilt according to their own preferences and comfort levels, making the sitting posture more comfortable.
Common Names and Functions
The cylinder under the chair is generally also called a "chair post" or "foot post". It is an important part of the chair, mainly serving to support the overall structure and keep the chair stably standing on the ground. At the same time, it can enhance the stability of the chair, preventing the chair from sliding during use and avoiding accidental falls caused by sliding. In addition, the bottom of the chair post usually has certain anti-slip and wear-resistant designs, which can reduce friction with the ground, prevent ground wear, and extend the service life of the ground. Moreover, it has to bear the weight of the user and various wear and tear during daily use, ensuring that the chair can be used normally for a long time.
Maintenance-Related
When the office chair cylinder (gas lift) malfunctions and causes the chair to sink, an office chair sinking repair kit can be used for repairs. This kit is suitable for cylinders with a diameter of 25 - 28 millimeters (0.98 - 1.1 inches) and is applicable to most office chairs, including tools such as stainless steel office chair clamps. Its installation is simple, without the need to disassemble the chair or the cylinder. After installation, it allows the chair to rotate smoothly, restores normal usage functions, and extends the service life of the office chair.
