Using these dining chairs is easy. Just place them around your dining table and start enjoying your meals in comfort. When it comes to cleaning, use a soft, damp cloth to wipe the eco - leather upholstery. Avoid using harsh chemicals as they may damage the material. For the metal frame, a dry cloth is enough to keep it looking shiny. Keep the chairs away from direct sunlight for long periods to prevent color fading. Since the product has a Prop65 warning due to formaldehyde, make sure to keep it in a well - ventilated area. If you notice any loose parts or damage, contact the seller for assistance.
