Using your Mila side chair set is easy. Just place the chairs around your table, and they're ready for use. You can add a bench to increase seating capacity. When it comes to cleaning, use a soft, dry cloth to wipe the surface regularly. Avoid using harsh chemicals as they may damage the washed grey finish. For the polyester - upholstered seats and backs, you can vacuum them gently to remove dust. If there are any spills, clean them up immediately with a mild detergent and a damp cloth. Place the chairs in a dry area, away from direct sunlight to prevent the color from fading. This will help keep your chairs looking great for years to come.
