Reclining Adjustable Office Chair
The method for adjusting a reclining office chair mainly consists of four steps: unlocking, adjusting the tension, locking the angle, and returning to an upright position. Specific operations should be adjusted according to the chair model. Here are the detailed instructions:

1. Unlocking the Reclining Function
The reclining function of most office chairs is activated by an unlocking handle. Typically, the handle is located on the right side of the chair (some models have it on the left) and is shaped like a long bar or cylinder. To operate, maintain an upright sitting posture and gently pull the handle with your right hand. You will hear a โclickโ sound or feel the backrest loosen, indicating that the reclining function has been unlocked. If the chair does not have a clear handle, try looking for a switch that can be toggled under the seat cushion. Some executive chairs require pulling up the adjuster while leaning back simultaneously to unlock.
2. Adjusting the Reclining Tension
The reclining tension affects the support feel of the backrest and should be adjusted according to your body weight and habits. Near the front of the chair's base, there is usually a cylindrical knob marked with โ+โ and โ-โ symbols or arrow indicators. Turning the knob clockwise increases the tension (suitable for users with a heavier body weight or those who prefer firm support), while turning it counterclockwise decreases the tension (suitable for users with a lighter body weight or those seeking a softer feel). It is recommended to make small, multiple adjustments until the backrest's rebound force matches your body's reclining force.
3. Locking the Reclining Angle
Some chairs support fixing the reclining angle, which is suitable for resting or reading scenarios. The locking function is usually achieved through a control lever on the right side of the seat cushion: first pull out the control lever to unlock the angle limit, slowly lean back to a comfortable position (such as 120ยฐ-135ยฐ), and then gently push the control lever back to complete the locking. If the chair does not have a locking function, the reclining angle will change freely with your body movements, and you will need to adjust the tension to maintain balance.
4. Returning to an Upright Position
When finishing reclining, you need to return the chair to an upright position. First pull out the control lever (or toggle the unlocking switch) outward, while gently pushing the backrest with your back. The chair will slowly rebound to a vertical position, and finally push the control lever back to lock it. If the chair does not have a locking mechanism, simply sit up straight, and the backrest will automatically rebound due to the tension.
Notes: The adjustment methods for different models of office chairs vary. For example, the Heibai Diao P2Ultra may adopt a segmented reclining design, while the Jingzao Z9Ultra second generation may support infinite adjustment; some executive chairs require pressing the button in front of the seat cushion to unlock the reclining function. If the operation is not smooth, it is recommended to consult the chair's manual or contact after-sales service to confirm the specific steps.
