1. Attach the Casters to the Base: Insert the five casters into the holes at the end of each leg of the chair base. Push firmly until they click into place.
2. Install the Gas Lift: Place the gas lift cylinder into the center hole of the chair base.
3. Attach the Mechanism to the Seat: Secure the seat mechanism to the underside of the seat cushion using the provided screws. Ensure the front of the mechanism aligns with the front of the seat.
4. Connect the Seat to the Gas Lift: Carefully place the assembled seat onto the gas lift cylinder.
5. Attach the Armrests: Secure the armrests to the sides of the seat cushion using the designated screws. Do not fully tighten yet.
6. Attach the Backrest: Align the backrest with the armrests and the seat. Secure the backrest to the armrests and/or seat using the remaining screws. It is often easier to loosely attach all screws before fully tightening any of them.

5. Operating Instructions

Your JUMMICO Gaming Chair is designed with several adjustable features to enhance your comfort and support.

• Seat Height Adjustment: To adjust the seat height (range: 15.2" to 18.3"), pull the lever located under the right side of the seat upwards. While pulling the lever, stand up to raise the seat or remain seated to lower it. Release the lever at the desired height.
• Backrest Recline Function: The chair features an adjustable back angle, allowing it to recline between 90° and 135°. To recline, pull the lever located under the left side of the seat outwards. Lean back to the desired angle and push the lever inwards to lock the backrest in position. To return to an upright position, pull the lever outwards and lean forward.
• 360-Degree Swivel: The chair is equipped with a 360-degree swivel function, allowing for easy rotation and movement without needing to reposition the entire chair.
• Rocking Function: The entire chair can rock back and forth. This function is typically controlled by a knob under the seat that adjusts the tension of the rocking mechanism. Turn clockwise to increase tension (less rocking) and counter-clockwise to decrease tension (more rocking).

• Hardware Check: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
• Caster Care: Keep the casters clean from hair, dust, and debris to ensure smooth rolling.
• Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the material to fade or crack.
