Adjusting Office Chair to the Lowest Position
The method for adjusting an office chair to its lowest position varies depending on the type of adjustment mechanism, as detailed below:

Pneumatic Adjustment (Most Common)
Pneumatic adjustment is the most prevalent height adjustment method in current office chairs, with the core component being a pneumatic rod. When operating, sit steadily on the chair, ensuring both feet are on the ground to maintain balance. Locate the height adjustment lever on the right side beneath the seat, usually a long lever. Grasp the adjustment lever with your hand and gently lift it upwards to release the lock on the pneumatic rod. At this point, keep the lever lifted and rely on your body weight to slowly and steadily sink down, causing the chair to lower accordingly. When the seat reaches the desired height, release the lever to lock the height in place. For inflatable seats, locate the knob on the pneumatic rod and rotate the chair clockwise to lower the height.
Mechanical Adjustment (Screw/Rotary Type)
Mechanical adjustment is more commonly found in older or specially designed office chairs, with a relatively straightforward but physically demanding adjustment method. Locate the adjustment knob or screw with a fixing function at the center or side of the chair base. To lower the height, rotate the knob clockwise (usually following the principle of 'tighten right, loosen left', but clockwise for lowering). If it's an old-style chair with a fixing screw, first use a tool (such as a wrench) to loosen the screw counterclockwise, then manually press the seat down to the desired height, and finally tighten the screw clockwise again to secure it.
Electric Adjustment (High-End Type)
Electric adjustment is commonly found in high-end office chairs and offers the simplest operation. On the control panel of the armrest or base of the seat, locate the button marked with an up-and-down icon. Press the button to automatically lower the chair without manual operation.
Precautions:
- Apply moderate force during adjustment to avoid violent operations that may damage the chair or pose safety risks.
- When adjusting to the appropriate height, ensure both feet are flat on the ground, thighs are parallel to the ground, and knees are naturally bent at a suitable angle to maintain a comfortable sitting posture.
- Different brands and models of office chairs may have slightly different adjustment methods, but the basic principles are largely the same. If you encounter difficulties in adjustment or are unsure how to operate, it is recommended to consult the product manual or contact after-sales service.
