Using these folding chairs is a breeze. Just unfold them and place them where you need seating. They're great for commercial events, parties, or even as extra chairs at home. When using, make sure the legs are fully extended and locked in place to ensure stability. As for maintenance, wipe the fabric seats and backs with a damp cloth regularly to keep them clean. Avoid using harsh chemicals as they might damage the fabric. For the metal frame, a dry cloth is enough to remove dust. If there are any scratches on the powder - coated finish, you can touch them up to prevent rust. Store the chairs in a dry place when not in use to prolong their lifespan. And remember, they come with a 2 - year normal - use warranty, so you can use them with confidence.
