Using your Adirondack chair set is a breeze. Just place the chairs and ottomans on your patio or porch, and you're ready to relax. When it comes to weight, remember that each chair can hold up to 350 lbs, so don't overload it. For cleaning, simply use a mild soap and water to wipe down the poly resin surfaces. Avoid using abrasive cleaners as they might damage the UV treatment. Since the set is weather - resistant, it can stay outside all year. But in extremely harsh weather like heavy snow or strong storms, you might want to cover it or move it indoors to extend its lifespan. Assembly is quick, taking 30 minutes or less. Just follow the fully illustrated instructions and use the included tools. If you have any issues during assembly, feel free to contact customer support.
