Using these chairs is a breeze. Just unfold them and place them where you need seating for your indoor or outdoor event. They're so lightweight that you can easily move them around and store them away when not in use. When it comes to maintenance, since they're made of UV - stabilized polypropylene resin and don't need repainting, you just need to wipe them down with a damp cloth if they get dirty. Avoid dragging them on rough surfaces to prevent scratches. Don't exceed the 800 lb. weight capacity to keep the chairs in good shape. If you're using them outdoors, it's a good idea to store them indoors during extreme weather conditions to extend their lifespan.
