Using these pillows is a breeze. You can place them on your indoor sofas, chairs, or outdoor patio furniture to instantly upgrade the look. When using outdoors, make sure to position them in a spot that gets a good mix of sun and shade. There's no need for any assembly, so you can start using them right away. As for maintenance, these pillows are easy to clean. Just spot - clean any stains with a mild detergent and water. Since they are water - resistant, they can handle a bit of light rain, but it's best to bring them indoors during heavy downpours. They are also resistant to mold and mildew, but if you notice any signs, clean them promptly. And remember, these pillows are for personal use, not for commercial purposes.
