Using these Milano Leather Dining Chairs is easy. Just place them around your dining table and you're ready to enjoy your meals. When sitting, make sure to distribute your weight evenly to avoid any unnecessary stress on the chair. As for cleaning, use a soft, damp cloth to wipe the leather surface regularly. Avoid using harsh chemicals as they can damage the leather. If there are any spills, clean them up immediately. For the black metal legs, you can use a dry cloth to dust them. Store the chairs in a dry place to prevent rusting of the metal legs. Also, don't stack heavy objects on the chairs to maintain their shape and durability.
