Using these folding chairs is a breeze. Just unfold them and place them where you need seating, whether it's indoors or outdoors. They're great for commercial events, offices, or any gathering. When you're done, fold them up and stack them neatly to save space. As for maintenance, a simple wipe-down with a damp cloth will keep them clean. The stain-resistant polypropylene means spills won't be a big problem. Avoid using abrasive cleaners that could damage the finish. Also, be careful not to exceed the 650 lbs weight limit to ensure the chairs' long - term stability. And remember, the non - marring floor caps are there to protect your floors, so don't remove them.
