Using these barstools is a breeze. First, assemble them according to the included instructions. They're great for outdoor bars, bistro sets, or just relaxing in your backyard. When using, make sure the floor is flat to prevent tipping. In terms of maintenance, since they're made of rust - resistant aluminum, you don't need to do much. Just clean them with mild soap and water occasionally. If you live in an area with extreme weather, it's a good idea to store them indoors during the harshest seasons to extend their lifespan. Avoid using abrasive cleaners as they may damage the copper finish.
