Using these dining chairs is easy. Just assemble them following the included instructions. They're great for daily dining or special gatherings. When it comes to maintenance, use a soft, damp cloth to wipe the Lucite polycarbonate parts. For the matte - black metal base, a dry cloth is usually enough. Avoid using harsh chemicals as they might damage the finish. Also, when stacking the chairs, do it gently to prevent scratches. Keep them in a dry place to avoid rusting of the metal parts.
