Using your Christopher Knight Home® Cape Coral Outdoor Contemporary Aluminum Dining Chairs is easy. Just place them on your patio or in your garden where you'd like to have your outdoor meals. They're great for casual dinners or small gatherings. When it comes to assembly, follow the easy - to - understand instructions that come with the set and use the included tools. You'll have them set up in no time. As for maintenance, since the chairs are made of rust - resistant aluminum, they can withstand the elements. But it's a good idea to clean them regularly with a mild soap and water. Wipe them dry after cleaning to keep them looking their best. Avoid using abrasive cleaners as they may scratch the frames. Also, if there are strong winds or storms coming, it's wise to store the chairs indoors or in a protected area to prevent any damage.
