Using this gaming chair is a breeze. First, adjust the seat height using the pneumatic lever to find your most comfortable position. You can swivel the seat 360 degrees to easily reach different areas around you. For reclining, use the lever on the side to adjust the backrest from 95 to 175 degrees. If you want to use the footrest, just pull the loop and flip it up. The lumbar pillow has a vibrating massage function; simply plug the 3 - foot USB plug into a power source to enjoy. When it comes to maintenance, wipe the LeatherSoft material with a soft, damp cloth regularly to keep it clean and looking good. Avoid using harsh chemicals as they may damage the material. Also, make sure to check the 5 - star nylon base and casters periodically for any signs of wear or looseness. If you need to move the chair, be gentle to prevent any damage to the base or casters. Remember, this chair is designed for long - term use, so take good care of it to ensure its durability.
