Using your Christopher Knight Home® Dark Grey Arlington Corner Sofa Set is a breeze. You can place it in your garden, patio, or any outdoor area you like. It's great for hosting parties or just relaxing on your own. When it comes to assembly, just follow the instructions that come with the set and use the provided tools. As for maintenance, since the cushions are water - resistant, you can simply wipe them clean with a damp cloth when they get dirty. For the acacia wood, you can occasionally clean it with a mild soap and water solution. Avoid leaving the set in standing water for long periods, as this might affect the wood's durability. Also, during extreme weather conditions like heavy storms or snow, it's a good idea to cover the set or store it indoors to ensure its longevity.
