Rocking Office Chair Adjustment

The adjustment methods for a rocking office chair mainly include backrest recline, height, forward-backward rocking, and other special function adjustments. The specific operations are as follows:

Backrest Recline Adjustment

The backrest recline function can meet different sitting posture needs. The adjustment steps are as follows:

1. Locate the adjustment handle: It is usually located on the lower right side of the seat. Some models may have it designed on the left side or the side of the backrest.
2. Unlock and adjust: After sitting firmly, pull the handle. Lean back slightly with your back, and the backrest will tilt with the movement. Release the handle to fix the current angle.
3. Return to the upright position: When you need to adjust it back to the upright state, pull the handle again, lean forward slightly with your back, and the backrest will automatically spring back to the initial position.
   Note: Avoid sudden force during adjustment to prevent handle damage or the backrest from rebounding too quickly, which may cause safety hazards.

Height Adjustment

The seat height is adjusted through a gas lift rod, and the operation needs to be combined with body weight and handle control:

1. Raise the seat: After sitting firmly, pull up or press the lifting handle below the seat. The seat will rise slowly due to the action of the internal gas lift rod. Release the handle to lock it when reaching the desired height.
2. Lower the seat: Maintain the sitting posture, pull up or press the handle while applying downward body weight pressure. The seat will descend evenly. Release the handle to fix it when in place.
3. Comfort standard: After adjustment, ensure that your elbows are bent at 90°-100°, your thighs are parallel to the ground, your eyes are level with the computer screen, and your waist is supported by the backrest.
   Tip: If the gas lift rod fails, it may be due to the aging of the internal seals, and you need to contact after-sales service for replacement.

Forward-Backward Rocking Adjustment

The rocking amplitude adjustment is achieved by rotating the black cylinder in front of the gas lift rod:

1. Locate the adjustment part: The black cylinder is located at the connection between the seat and the gas lift rod, and its surface may have scale markings.
2. Rotate and adjust: Rotate it clockwise to reduce the rocking amplitude and counterclockwise to increase it. After adjustment, test the stability.
   Note: Excessively increasing the rocking amplitude may lead to an unstable center of gravity. It is recommended to choose a moderate range according to the usage scenario (such as office work or rest).

Other Adjustment Functions

Some models support personalized adjustments such as backrest height, headrest, and damping:

• Backrest height adjustment: Move up and down through the buttons or slide rails on the side of the backrest to fit users of different heights.
• Headrest adjustment: Some headrests can be adjusted up and down, forward and backward, or rotated. You need to press the locking key to operate.
• Damping adjustment: Control the rebound speed of the backrest. Rotate the damping knob below the seat. Turn it clockwise to slow it down and counterclockwise to speed it up.
  Suggestion: Refer to the product manual for specific functions, and read the operation guide carefully before the first use.
