Operating Instructions
Ergonomic Design and Support

Height Adjustment
To adjust the seat height, locate the lever beneath the seat on the right side. Lift the lever up while applying or releasing weight from the seat to move it to your desired height. The seat height can be adjusted from 17 inches to 20 inches to accommodate various desk heights and user preferences.

Backrest Recline
The backrest can be reclined between 90° and 155°. To recline, lift the lever located on the side of the chair (typically the left side). Lean back to the desired angle and release the lever to lock the position. This feature allows for comfortable working, gaming, or napping positions.

Retractable Footrest
For added relaxation, the chair includes a retractable footrest. Pull the footrest out from beneath the seat when needed, and push it back in for storage. The footrest extends up to 15 inches, providing support for your legs during breaks or naps.
Linkage Armrests
The armrests are designed with a linkage mechanism, meaning they move in conjunction with the backrest when you recline. This ensures continuous arm support regardless of the recline angle, enhancing overall comfort.
360° Swivel and Universal Wheels
The chair features a 360° horizontal swivel, allowing for easy rotation and communication in any direction. Mute PU rolling wheels provide smooth movement across various floor surfaces without causing excessive noise or scratches.
Maintenance
Proper maintenance will extend the life and appearance of your GYMAX Gaming Chair:
- Cleaning: Wipe clean with a damp cloth. For tougher stains, use a mild soap solution and wipe dry immediately. Avoid using harsh detergents, abrasive cleaners, or solvents, as these can damage the PU and PVC leather.
- Regular Checks: Periodically inspect all bolts and screws to ensure they are tight. Re-tighten if necessary to maintain stability and prevent wobbling.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the leather to fade or crack. Position the chair away from direct sunlight if possible.
- Weight Distribution: Distribute your weight evenly when sitting to prevent undue stress on specific parts of the chair.
