Using these outdoor chairs is easy. First, assemble them following the included instructions. Once assembled, place them in your desired outdoor area like the backyard, patio, or deck. You can enjoy sitting on them during meals or just to relax outdoors. When it comes to maintenance, it's simple. Wipe the chairs with a damp cloth regularly to keep them clean. If there's any dirt or debris, a mild soap solution can be used. Avoid using abrasive cleaners as they may damage the black sand finish. In case of bad weather, it's a good idea to cover the chairs or store them indoors to extend their lifespan. Also, check the assembly parts periodically to make sure they're tight and secure.
