Office Chair Control Lever

The office chair control lever is usually located on the right or left side directly beneath the seat. Some multifunctional chairs may have two control levers, primarily used to control the height and the recline force of the chair back.

Control Lever for Height Adjustment

The control lever for pneumatic height-adjustable chairs comes in two types: lever-type and button-type. For the lever-type, pull the control lever outward or downward and hold it. For the button-type, simply press the button. To raise the seat, pull the control lever when no one is sitting on it. The rebound force of the high-pressure nitrogen gas inside will then push the seat upward. To lower the seat, pull the control lever while sitting on it. Your body weight will overcome part of the nitrogen gas pressure, allowing the seat to descend smoothly. For example, the lever on the right side of an executive chair is responsible for the height adjustment function. While sitting, gently lift it upward to raise the chair and press it downward to lower it. When adjusting the height, keep your buttocks on the seat and use your body weight to assist in the adjustment. The most comfortable position is when your knees are bent at a 90-degree angle and your feet can rest flat on the ground.

Control Lever for Chair Back Recline Force

The lever on the left side of an executive chair controls the recline force of the chair back. Lift the lever upward, and the chair can recline backward. Find your preferred angle and then press the lever down to lock it. Some high-end chairs come with a knob. By adjusting the knob, you can change the tightness of the recline. People with a larger body weight can tighten the knob to increase the recline resistance. If you want to relax during a lunch break, you can loosen the knob a bit.

Operation Precautions

When adjusting an office chair, be sure to maintain a correct sitting posture. Ensure that your feet are firmly on the ground and that your thighs and lower legs form a 90-degree angle as much as possible. This not only ensures the accuracy of the adjustment but also prevents physical injuries caused by improper posture. It is strictly prohibited to stand and forcibly掰动 (the correct English here should be 'manipulate' or 'force') the pneumatic rod during operation. Since your body weight is relatively large when standing, forcing the manipulation may cause the pneumatic rod to break, leading to safety accidents.
