Using these chairs is easy. Just place them where you want to enjoy the outdoors, whether it's around a dining table or as extra seating. Since they require no assembly, you can start using them right away. When it comes to weight, each chair can hold up to 250lbs, so make sure not to exceed this limit. For maintenance, keep them clean by wiping them with a damp cloth regularly. They are suitable for commercial use, but if used outdoors, it's a good idea to protect them from extreme weather conditions. You'll receive the exact product based on the options you choose, so double - check your selections before making a purchase.
