5. Operating Instructions
Your JUMMICO Gaming Chair offers multiple adjustment options for personalized comfort.
5.1. Height Adjustment
To adjust the chair's height, locate the lever on the right side beneath the seat. Pull the lever upwards while sitting to lower the chair, or pull it upwards while standing to raise the chair. Release the lever at your desired height. The chair offers approximately 10 cm of height adjustment.
5.2. Backrest Recline
The backrest can be reclined between 90 and 135 degrees. Pull the recline lever, typically located on the left side of the seat, and lean back to your desired angle. Release the lever to lock the backrest in position. This allows for various modes, including working (90°), reading (110°), music (130°), and rest (135°).

5.3. Lumbar Massage Function
The lumbar cushion features a 2-point high-frequency vibration massage function. Connect the USB cable from the lumbar cushion to a suitable USB power source (e.g., computer USB port, power bank, USB wall adapter). The vibration promotes blood circulation and helps alleviate sedentary stress.

For added relaxation, pull out the footrest located beneath the seat. Extend it fully to support your legs and feet, especially when reclining or taking a nap. Push it back in when not in use.

Both the headrest and lumbar cushions are adjustable vertically to align with your body's curves, providing effective support for your spine.
5.6. 360-Degree Rotation
The chair's base allows for full 360-degree swivel rotation, providing flexibility and ease of movement within your workspace.
6. Maintenance
- Cleaning Fabric: For general cleaning, use a soft cloth dampened with mild soap and water. Gently wipe the fabric surface. Avoid harsh chemicals or abrasive cleaners.
- Spot Cleaning: For spills, blot immediately with a clean, dry cloth. Do not rub, as this can spread the stain.
- Frame and Base: Wipe metal and plastic parts with a damp cloth.
- Casters: Periodically clean hair and debris from the casters to ensure smooth rolling.
- Fasteners: Every few months, check all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
7. Troubleshooting
- Issue: The chair does not recline to 150 degrees as expected.
Solution: The chair is designed to recline between 90 and 135 degrees. Please ensure you are not attempting to force it beyond this specified range. - Issue: Chair feels unstable or wobbly.
Solution: Check all screws and bolts, especially those connecting the backrest, armrests, and mechanism plate to the seat, and the base to the gas lift. Tighten any loose fasteners. - Issue: Massage function is not working.
