Using this chair is a breeze. First, adjust the seat height using the pneumatic adjustment under the seat until you find a comfortable position with your feet flat on the floor. Then, set the height and angle of the arms to support your elbows. You can also customize your comfort by adjusting the headrest and lumbar pillows. To recline, use the lever on the side of the chair and choose an angle between 87 and 145 degrees. If you want to rock, unlock the tilt lock mechanism. You can adjust the tilt tension to make it easier or harder to lean back. When it comes to maintenance, wipe the LeatherSoft surface with a soft, damp cloth regularly to keep it clean. Avoid using harsh chemicals as they may damage the material. And make sure to check the casters and the 5 - star base from time to time to ensure they are in good condition. Remember, the item description might include features from other variants, so double - check if you have any specific questions.
