Using these dining chairs is a breeze. Just place them where you need seating, and you're good to go since they come pre - assembled. For everyday use, sit back and enjoy the support from the built - in bars. When there are spills, quickly grab a damp cloth to wipe them off. As for maintenance, keep them away from direct sunlight for long periods to prevent the antique white finish from fading. Check the metal wood screw reinforcements and floor glides regularly to make sure they're in good condition. If you notice any looseness in the mortise and tenon joints, don't worry, you can simply tighten the metal wood screws. And remember, each chair can hold up to 500 lbs, so avoid overloading them.
