Using this chair is a breeze. First, adjust the seat height using the pneumatic adjustment under the seat to find a comfortable position where your feet rest flat on the floor. You can also adjust the tilt tension using the knob to control how easy it is to lean back. To recline, use the lever on the side of the chair to set the angle between 87 and 145 degrees. If you want to lock the chair in an upright position or while rocking, use the tilt lock mechanism. For added comfort, adjust the height and pivot of the arms to support your upper body. When it comes to maintenance, wipe the LeatherSoft material regularly with a soft, damp cloth. Avoid using harsh chemicals as they may damage the material. If the headrest or lumbar pillows get dirty, you can remove them and clean them according to the care instructions. Also, check the 5 - star nylon base and casters from time to time to make sure they are in good condition and replace them if necessary.
