Operating Instructions
Your Dowinx gaming chair offers several adjustable features to customize your seating experience.
- Height Adjustment: To adjust the chair's height, locate the lever under the seat on the right side. Pull the lever up while seated to lower the chair, or pull it up while standing to raise it. Release the lever at your desired height.
- Backrest Recline: Use the recline lever, typically on the left side of the seat, to adjust the backrest angle. The backrest can recline up to 145 degrees. Lean back to your desired angle and release the lever to lock it in place.
- Armrest Adjustment: The armrests can be adjusted for height and rotation. Look for buttons or levers on the armrests themselves to make these adjustments. Adjust them to support your elbows comfortably.
- Lumbar Massage Function: If your lumbar support cushion includes a massage function, connect it to a power source (e.g., USB port) as indicated in the specific instructions for the cushion. Activate the massage function via its integrated controls.
- Footrest Extension: Pull out the retractable footrest located under the seat for additional leg support when reclining. Push it back in when not in use.


Maintenance and Care
Regular maintenance will help preserve the appearance and functionality of your gaming chair.
- Cleaning: For general cleaning, wipe the PU leather and plastic parts with a soft, damp cloth. For stubborn stains, use a mild soap solution and wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Caster Wheels: Periodically check the caster wheels for hair or debris buildup and clean them to ensure smooth movement.
- Tighten Fasteners: Over time, screws and bolts may loosen. Periodically check all fasteners and tighten them as needed to maintain stability and safety.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the PU leather to fade or crack. Position your chair away from direct sunlight if possible.
- Weight Limit: Do not exceed the maximum weight capacity of 150 kg (330 lbs) to prevent damage to the chair and ensure user safety.
