Using these chairs is a breeze. Just place them at your counter and enjoy sitting on them. When sitting, make sure your weight is evenly distributed to avoid any undue stress on the legs. As for maintenance, wipe the leatherette parts with a soft, damp cloth regularly to keep them clean. Avoid using harsh chemicals as they may damage the leatherette. For the wooden parts, you can use a mild wood cleaner. Keep these chairs away from direct sunlight for long periods as it may fade the brown color. Also, be aware of the Prop65 warning on the product. Since it contains formaldehyde which is associated with cancer, follow the safety instructions on the warning label carefully.
