Operating Instructions
Your HeroSet Criss Cross Chair offers several adjustable features for personalized comfort and functionality.
Height Adjustment
To adjust the chair's height, locate the lever on the right side beneath the seat. Pull the lever upwards while seated to lower the chair, or stand up and pull the lever upwards to raise the chair. Release the lever at your desired height.
Tilt Function and Tension Control
The chair features a 90°-120° tilt function. Use the lever on the left side to lock or unlock the tilt mechanism. To adjust the tilt tension, rotate the round knob located beneath the seat. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).

The armrests can be adjusted from 0 to 90 degrees to accommodate various sitting postures and activities. They can also bear a maximum weight of 180 lbs.
- Unlock: Gently push the upright armrest inward to release the locking mechanism.
- Flatten: Lower the armrests to a flat position, extending the seat area.
- Raise and Lock: Raise the armrests to your desired angle. They can be locked at 5 different levels, including the upright position.

Multi-functional Use
The chair's design supports various activities and postures:
- Working Hours: Use in an upright position for desk work.
- Reading Time: Recline slightly for comfortable reading.
- Rest Time: Fully recline and extend the armrests for a relaxed posture.
- Leisure Time: Sit cross-legged or in other comfortable positions for relaxation or hobbies.
Maintenance
Proper care and maintenance will extend the life and appearance of your HeroSet Criss Cross Chair.
- Cleaning: The chair is upholstered with scratch-resistant and waterproof PU leather. For general cleaning, wipe the surface with a soft, damp cloth. Avoid using abrasive cleaners, harsh chemicals, or solvents, as these can damage the material.
- Spills: In case of spills, wipe them immediately with a clean, dry cloth to prevent staining.
- Pet-Friendly: The PU leather is designed to be pet-friendly and resistant to cat scratches. It also resists pet hair from sticking, making cleaning easier.
- Hardware Check: Periodically check all screws and bolts to ensure they are tight. Re-tighten as necessary to maintain stability and safety.

Troubleshooting
If you encounter any issues with your chair, refer to the following common solutions:
- Chair not adjusting height: Ensure the gas lift lever is fully engaged. Check if the air rod is correctly inserted into the base plate and central base tube. If the issue persists, the gas lift cylinder may need replacement.
- Wheels not rolling smoothly: Check for any debris (hair, dust, etc.) caught in the castor wheels. Clean them if necessary. Ensure all castors are fully inserted into the foot stools.
- Chair feels unstable or wobbly: Re-tighten all assembly screws, especially those connecting the foot stools to the central base tube and the base plate to the seat cushion. Ensure the air rod is securely seated.
- Armrests not adjusting: Verify that the armrest is pushed inward to unlock before attempting to adjust its angle. Check for any obstructions in the adjustment mechanism.
If these steps do not resolve the issue, please contact HeroSet customer support for further assistance.
