Using the chair is easy. First, adjust the seat height using the pneumatic adjustment lever under the seat to find your most comfortable sitting position. You can then swivel the seat 360 degrees to move around easily. To recline, use the reclining back lever to adjust the angle between 95° and 175°. The padded armrests will recline with the backrest. If you want extra comfort, pull out the slide - out footrest. The removable massaging lumbar pillow can be attached to the backrest and connected to a power source via the 3 - foot USB cord for a relaxing massage. When it comes to maintenance, use a soft, damp cloth to clean the LeatherSoft upholstery regularly. Avoid using harsh chemicals as they may damage the material. Also, check the roller wheels from time to time and clean any debris that may get stuck in them to ensure smooth movement. When not in use, it's best to keep the chair in a dry and cool place to extend its lifespan.
