Operating Instructions
The VINGLI Criss Cross Chair offers several adjustable features for personalized comfort.
1. Height Adjustment:
To adjust the chair's height, locate the lever on the right side, beneath the seat. While seated, pull the lever up to lower the chair. To raise the chair, stand up slightly and pull the lever up. Release the lever at your desired height.
2. Tilting/Rocking Function:
The chair features a 90°-120° rocking function. To enable rocking, pull the lever on the left side, beneath the seat, outwards. To lock the chair in an upright position, push the lever inwards. The tilt tension knob, located at the front of the mechanism plate, can be rotated to adjust the resistance of the rocking motion.

3. Flip-Up Armrests:
The armrests can be flipped up to allow the chair to slide further under a desk or for more space. To raise an armrest, simply lift it upwards until it locks into the vertical position. To lower it, gently pull it down.
4. 360° Swivel and Casters:
The chair is equipped with a 360° swivel mechanism and flexible casters, allowing for easy rotation and movement across your workspace without needing to stand up.

Maintenance
Proper care will extend the life and appearance of your VINGLI Criss Cross Chair.
Cleaning the PU Leather:
- For general cleaning, wipe the surface with a soft, damp cloth.
- For tougher stains, use a mild soap solution on a soft cloth, then wipe clean with a separate damp cloth and dry thoroughly.
- Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the PU leather.
- Do not expose the chair to direct sunlight for prolonged periods, as this may cause fading or cracking of the material.
General Maintenance:
- Periodically check all screws and bolts to ensure they remain tight. Retighten as needed to maintain stability.
- Inspect casters for any debris (hair, lint) that might hinder smooth movement and clean if necessary.
