Operating Instructions
Your COLAMY Gaming Chair offers several adjustable features for personalized comfort.
1. Seat Height Adjustment
To adjust the seat height, locate the lever on the right side, beneath the seat. Pull the lever up while seated to lower the chair, or pull it up while standing to raise the chair. Release the lever to lock the height.

2. Backrest Recline Function
The backrest can be reclined between 90 and 150 degrees. Pull the recline lever, typically on the right side of the seat, and lean back to your desired angle. Release the lever to lock the backrest in position.
3. 4D Armrest Adjustments
The 4D armrests offer multiple adjustment options:
- Height Adjustment: Press the button on the side of the armrest and move it up or down.
- Forward/Backward: Slide the armrest pad forward or backward.
- Left/Right: Slide the armrest pad left or right.
- Rotation: Rotate the armrest pad inward or outward.

4. Tilt Tension Adjustment
The tilt tension knob, located underneath the seat, allows you to control the resistance when reclining. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
5. 360-Degree Swivel
The chair features a 360-degree swivel for easy movement and access to your workspace.

- Caster Care: Keep casters free of hair and debris to ensure smooth rolling.
- Material Care: The chair is made of PU leather and carbon fiber leather. Avoid prolonged exposure to direct sunlight or extreme temperatures to prevent material degradation.
