2. Safety Information
Please read and understand the following safety guidelines before using the footrest:
- Do Not Stand On The Foot Rest: This product is designed for foot support only. Standing on it may cause damage to the unit or lead to personal injury.
- Ensure the footrest is placed on a stable, flat surface to prevent accidental movement.
- Keep hands and fingers clear of moving parts during height and angle adjustments.
3. Setup
The HUANUO Adjustable Desk Footrest HNFR3 comes pre-assembled for immediate use. No tools are required for assembly.
3.1 Initial Placement
- Remove the footrest from its packaging.
- Place the footrest on the floor under your desk or in your desired seating area.
- Ensure the non-slip feet are securely positioned on the floor to enhance overall stability.
3.2 Height Adjustment
The footrest offers three manual height positions to suit your needs. To adjust the height:
- Gently lift the footrest platform.
- Locate the adjustment mechanism on the sides of the base.

4. Operating Instructions
4.1 Angle Adjustment
The footrest platform is designed to tilt freely between -30° and +30°. This dynamic movement encourages leg and foot circulation, preventing stiffness. The angle cannot be fixed, allowing for continuous micro-adjustments by the user.
- Place your feet on the footrest surface.
- Apply gentle pressure with your feet to tilt the platform to your preferred angle.
- Allow the footrest to rock back and forth naturally to promote leg movement.

4.2 Massage Surface Use
The footrest features a large non-skid surface (18" X 13") with geometric circular bumps. This textured design provides a gentle massage effect, which can help relieve fatigue and enhance comfort during use.
- Place your bare feet or feet with socks directly onto the textured surface.
- Gently move your feet across the bumps to stimulate circulation and reduce stress.

5. Maintenance
To ensure the longevity and hygiene of your HUANUO footrest, follow these simple maintenance steps:
- Cleaning: The footrest surface is washable and easy to clean. Use a damp cloth with mild soap and water to wipe down the surface. Avoid harsh chemicals or abrasive cleaners.
- Drying: Allow the footrest to air dry completely before reuse.
- Inspection: Periodically check for any signs of wear or damage to the adjustment mechanisms or non-slip feet.

6. Troubleshooting
If you encounter any issues with your footrest, please refer to the following common solutions:
- Footrest feels unstable: Ensure the footrest is placed on a flat, even surface. Check that both sides of the height adjustment mechanism are securely locked into the same position.
- Difficulty adjusting height: Make sure to lift the platform slightly before attempting to change the height setting. Do not force the mechanism.
- Footrest slides on the floor: Verify that the non-slip feet are clean and free of debris. If used on a very smooth surface, consider placing a non-slip mat underneath.
If the problem persists, please contact customer support.
