Office Chair Operation
The operation of an office chair mainly includes height adjustment, armrest adjustment, backrest recline adjustment, as well as other operations and precautions, as detailed below:
Height Adjustment: Locate the hand control device. You can adjust the height by pulling up the corresponding lever or turning the knob. Some pneumatic models allow you to pump the lever (repeatedly push it up and down to raise or lower the seat). If you're unsure which lever controls the height, read the instructions or try each one individually. Adjust the seat height until it feels comfortable. Operate gently, moving a few inches (or centimeters) at a time, and return the lever to its original position when finished. For some models, pulling the lever up raises the seat, and pressing it down lowers it. If adjusting from a standing position, position the front of the chair just below your knees so you can sit comfortably with your feet flat on the floor. When working on a computer, keep your eyes level with the monitor. If you can't adjust the monitor height, adjust the seat height instead. For desk work, keep your elbows at desk height. When sitting for long periods, adjust the chair height so your feet rest flat on the floor. For executive chairs, the right lever controls the height. While seated, gently lift up to raise the chair and press down to lower it. Don't lift your buttocks off the seat when adjusting the height; let your body weight 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 floor.
Armrest Adjustment: The armrests can be adjusted up and down, and some armrest surfaces can rotate 360 degrees with two rotating joints. If your chair has armrests, adjust their height. If you don't need arm support, you can remove the armrests or lower them to avoid obstruction. If the armrests prevent you from comfortably sliding your knees under the desk, lower or remove them as well.
Backrest Recline Adjustment: For executive chairs, the left lever controls the backrest recline force. Pulling it up allows you to recline backward. Find your preferred angle and press down to lock it. Some high-end chairs have a knob that allows you to adjust the recline tension. If you're heavier, tighten it; if you want to relax during a lunch break, loosen it.
Other Operations and Precautions: Do not forciblyๆฐๅจ (this should be translated as 'twist' or 'manipulate') the pneumatic rod while standing, as it may cause the rod to break. Change your sitting position every 15-30 minutes, such as briefly leaning forward and then sitting up straight again, or slightly shifting the weight distribution on the chair. If the chair is too high, prepare a footrest, slide it under the desk, and place your feet on it.
