Using your new gaming and office chair is easy. First, adjust the height of the seat using the pneumatic height adjustment lever until you're at a comfortable level. You can tilt the chair back and lock it in an upright position with the tilt lock mechanism. If you want to change how much resistance there is when leaning back, use the tilt tension adjustment knob. To make the most of your chair, don't over - lean or put too much weight on the arms. When cleaning, use a soft, damp cloth to wipe the LeatherSoft upholstery. Avoid using harsh chemicals as they can damage the material. Keep the chair away from direct sunlight for long periods to prevent the color from fading. Regularly check the 5 - star nylon base and transparent wheels for any signs of wear and tear. With proper care, your chair will serve you well for a long time.
