There are various types and features of office chairs with height adjustment functions. Here is a detailed introduction for you:

Common office chair products with height adjustment functions

• Jingdong Jingzao Z5 Pro Ergonomic Chair: This chair is equipped with a 50mm adjustable backrest. This design allows users to precisely find a comfortable support zone according to their physical condition and sitting posture needs. People of different heights and body types can adjust the backrest height to make it better fit the back, providing effective support, reducing back pressure, and enhancing sitting comfort.
• Henglin Counterattacker II Ergonomic Chair: The backrest supports 4cm stepless height adjustment and is paired with a 10° self-adapting floating lumbar support. Stepless height adjustment means that the backrest height can be adjusted more flexibly and smoothly without fixed gear limitations. At the same time, the self-adapting floating lumbar support can automatically adjust its angle according to the body's movements and postures, providing precise support for the waist. Whether a person is 155cm or 185cm tall, they can adjust the backrest height to make the lumbar support precisely prop up the waist and maintain a correct sitting posture.
• Sihoo M56 II: The entire backrest can be adjusted up and down independently, enabling precise lumbar support. For tall people, after adjusting the backrest height, they can not only get good lumbar support but also have effective support for the neck, preventing neck fatigue and soreness caused by long-term neck suspension and improving work and study efficiency.

Types and principles of height-adjustable chairs

A height-adjustable chair is a functional seat that adjusts the height of the seat plate through a height positioning device. Common types include pneumatic, hydraulic, and mechanical types, and there are also other types such as screw types.

• Pneumatic type: It uses a high-pressure nitrogen gas cylinder to achieve smooth height adjustment. When a user needs to adjust the seat height, by operating the control lever, the nitrogen pressure inside the gas cylinder changes, enabling the seat to rise or fall. The operation is convenient, and the height adjustment process is relatively stable.
• Hydraulic type: It controls the height through the principle of pressure. Using the pressure transmission characteristics of liquids, when pressure is applied to the hydraulic system, the seat will move up and down under the action of the pressure, providing relatively stable support force.
