Using your new 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 reach different areas easily. To recline, use the lever on the side and adjust it anywhere from 95 to 175 degrees. If you want to use the footrest, just pull the loop and flip it up. For the lumbar massage, plug the 3 - foot USB plug into a power source. When it comes to maintenance, wipe the LeatherSoft material regularly with a soft, damp cloth to keep it clean. Avoid using harsh chemicals as they can damage the material. If you're not using the lumbar pillow, you can remove it and store it. Be careful when moving the chair on the casters to prevent scratches on the floor.
