Using these pillow covers is a breeze. Just unzip the cover and insert your pillow. You can use them on your indoor sofa, outdoor patio chairs, or anywhere you want to add a coastal touch. When it comes to cleaning, you can spot - clean minor stains with a gentle detergent and a soft cloth. For a deeper clean, you can machine - wash them in cold water on a gentle cycle. Then, tumble dry on low. Keep them away from sharp objects to avoid tears. Since they're water and UV resistant, they can stay outdoors, but it's a good idea to bring them inside during harsh weather to extend their lifespan. No assembly is needed, so you can start using them right away after you receive them.
