Operating Instructions and Adjustments
Your Desky Vanguard Gaming Chair offers multiple adjustment options for personalized comfort and ergonomic support.
1. Seat Height Adjustment
To adjust the seat height, locate the lever on the right side beneath the seat. While seated, pull the lever up to lower the seat. To raise the seat, stand up and pull the lever up. Release the lever to lock the height.
2. Recline Function and Lock
The chair features a 4-level reclining lock, allowing recline up to 135°. To recline, pull the recline lever (often on the left side) and lean back. Release the lever at your desired angle to lock it in place. To return to an upright position, lean forward slightly while pulling the lever.

3. Dual-Axis Adjustable Headrest
The headrest can be adjusted for height, angle, and depth. Gently push or pull the headrest to change its angle and depth. To adjust the height, grasp both sides of the headrest and slide it up or down to your preferred position.

4. Ergonomic Lumbar Support
The lumbar support features adjustable extension and adaptive rotation. To adjust the lumbar support, locate the controls on the backrest. These allow you to move the support in and out, and rotate it to align with your spine's natural curve.

5. 4D Mechanical Armrests
The armrests are fully adjustable for height, depth, width, and angle. Use the buttons or levers on the armrests to:
- Height: Press the button on the side and slide the armrest up or down.
- Depth (Forward/Backward): Slide the armrest pad forward or backward.
- Width (In/Out): Slide the armrest pad left or right.
- Angle (Pivot): Rotate the armrest pad inward or outward.

6. Seat Depth Adjustment
To adjust the seat depth (up to 18.1 inches), locate the lever or button typically on the left side beneath the seat. While seated, pull the lever/button and slide the seat forward or backward to your preferred depth. Release to lock.
Maintenance
- Cleaning: For the mesh fabric, use a soft cloth dampened with mild soap and water. Avoid harsh chemicals. For the frame, wipe with a dry or slightly damp cloth.
- Inspection: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
- Casters: Keep casters free of hair and debris to ensure smooth movement.
- Avoid Overloading: Do not exceed the maximum weight capacity of 330 lbs.
