Using this chair is super easy. First, adjust the seat height to your liking using the pneumatic seat height adjustment lever under the seat. You can also fine - tune the tilt tension with the knob on the side to control how far back the chair leans. The tilt lock mechanism lets you either lock the chair in an upright position or rock back and forth as you like. For added comfort, adjust the padded flip - up arms according to your needs. 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 5 - star nylon base and dual - wheel casters from time to time to make sure they're in good condition and rolling smoothly. Keep the chair away from sharp objects to prevent any tears in the upholstery.
