Using these dining chairs is a breeze. Just assemble them following the simple instructions provided, and they're ready for use. For casual or formal dining, just pull out a chair and sit down comfortably. When it comes to maintenance, keep the chairs clean by using a soft, dry cloth to wipe away dust regularly. If there are any spills on the gray upholstery, gently blot the area with a damp cloth and mild detergent, then dry it quickly. Avoid using harsh chemicals or abrasive materials as they can damage the upholstery or the black frame. Place the chairs on a stable floor to maintain their stability. And if you need to move them, lift them carefully instead of dragging to prevent scratches on the legs and the floor. Enjoy your new dining chairs for years to come!
