Office Chair Rocking Chair Adjustment

The following are the methods for adjusting the height and rocking amplitude of an office chair rocking chair:

I. Height Adjustment Operations

1. Locate the Adjustment Components

   • Common adjustment devices are located on the side or front below the seat. There are three types:
     • Pull-up Lever: A metal or plastic elongated handle. Most office chairs adopt this design and require manual pulling.
     • Press-down Handle: Some brands (such as Xiaomi) set circular or square press buttons on the armrests or the side of the chair body. Pressing them allows for adjustment.
     • Foot-operated Device: A few models require stepping on the metal rod below the seat with your feet and adjusting the height with your body weight.

2. Operation Procedures

   • Raise the Seat: Sit steadily and then pull up or press the adjustment handle. No extra force is needed. The seat will automatically rise due to the internal gas lift and lock in place after reaching the desired height when you release the handle.
   • Lower the Seat: Also sit steadily. While pulling up or pressing the handle, apply downward pressure with your body weight (such as leaning forward). The seat will slowly descend and be fixed in place when it reaches the right position after you release the handle.

3. Handling Special Situations

   • If the lever fails (no response after pulling), it may be due to a lack of gas in the gas lift or a jam. You can slightly lift the seat and then operate it again. If it still doesn't work, contact a professional for repair.
   • Electric adjustment chairs (high-end models) are controlled by electric buttons (such as the “↑/↓” keys) on the armrests. Before operation, ensure that the power supply is properly connected.

II. Rocking Amplitude Adjustment

The rocking amplitude of some office chair rocking chairs can be adjusted through the black cylindrical device in front of the chair's gas lift:

• Operation Method: Rotate the cylinder left or right with your hand. Turning it clockwise or counterclockwise can increase or decrease the rocking amplitude. Stop when it reaches a comfortable state.

III. Reference Standards for the Correct Height

1. Elbow Angle: The upper arm should be parallel to the spine, and the elbow should form a 90° right angle. Place your hands naturally on the desktop or keyboard.
2. Thigh Space: Your fingers should be able to slide freely between your thighs and the front end of the seat without any squeezing sensation.
3. Eye-level: When you open your eyes, your line of sight should fall in the center of the computer screen to avoid looking up or down.
4. Back Support: Keep your hips close to the backrest. You can place a cushion on your lower back to maintain a natural curve and reduce lumbar pressure.

Tip: Maintain a stable sitting posture during adjustment to avoid chair shaking or damage due to improper operation. If you encounter complex faults (such as gas lift leakage or electric system failures), it is advisable to contact the brand's after-sales service or professional repair personnel for handling.
