Using these chairs is a breeze. Just place them on your patio where you want to sit. They're stackable, so when you're done using them, stack them up neatly to save space. As for the cushions, they're water - resistant, but it's still a good idea to bring them inside during heavy rain. To clean the chairs, use a mild soap and water solution on the wicker and iron frames. Don't use any harsh chemicals as they might damage the wicker. If the cushions get dirty, follow the care instructions on the label. Keep the chairs in a dry place during the off - season to extend their lifespan. That way, you can enjoy these comfortable and stylish chairs for years to come.
