Using these folding chairs is super easy. Just unfold them and place them where you need seating. They're great for commercial events like conferences or in your home for parties. When it comes to weight, remember they can hold up to 300 lbs, so don't overload them. For maintenance, you can wipe the black patterned fabric upholstery with a damp cloth. Avoid using harsh chemicals as they might damage the fabric. The metal frame is powder-coated, which helps protect it from rust, but try to keep the chairs dry. When not in use, you can fold them up easily and store them away. Since they don't require assembly, you can start using them right out of the box.
