5. Operating Instructions
Your TRIUMPHKEY Gaming Chair offers several adjustable features for personalized comfort:
5.1. Height Adjustment
To adjust the chair height, pull the lever located on the right side of the seat upwards. While pulling the lever, lift your weight off the seat to raise it, or remain seated to lower it. Release the lever to lock the height.
5.2. Backrest Recline
To recline the backrest, pull the recline lever (typically on the right side, near the seat) upwards and lean back to your desired angle. Release the lever to lock the backrest in position. The chair supports recline angles from 90° to 135°.
Figure 5.1: Illustration of the adjustable recline function. This image demonstrates the chair's ability to recline from an upright 90-degree position to a relaxed 135-degree angle, along with 360-degree rotation and height adjustment.
5.3. Footrest Operation
To extend the footrest, pull it out from underneath the seat. To retract, push it back in until it is fully stored.
5.4. Lumbar Massage Function
The lumbar support cushion features a 2-point massage function. Connect the USB cable from the cushion to a compatible USB power source (e.g., power bank, computer USB port, or USB wall adapter). The massage function will activate, providing high-frequency vibration to help relax lumbar muscles and promote blood circulation.
5.5. Armrest Linkage
The armrests are designed with a linkage system that moves with the backrest when reclining, providing continuous support. They are not independently adjustable for height or rotation.
Figure 5.2: Depiction of the linkage armrest system. This image illustrates how the armrests adjust with the chair's recline, providing support in both upright (work) and reclined (rest) positions.
5.6. Ergonomic Support
The chair is designed to provide ergonomic support for various body parts, including the head, shoulders, back, and lumbar spine. Adjust the headrest and lumbar cushion positions to best suit your body's contours for optimal comfort and support.

6. Maintenance
Regular maintenance will prolong the life and appearance of your chair:
- Cleaning: For the fabric, use a soft, damp cloth with mild soap and water. Avoid harsh chemicals or abrasive cleaners. For the base and casters, wipe with a damp cloth.
- Inspection: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
- Caster Care: Clean any debris (hair, dust) from the casters to ensure smooth movement.
- Fabric Care: Avoid sharp objects that could tear or snag the fabric.
