These pillows are super easy to use. Just place them on your sofa, chair, or bed to instantly spruce up your space. You can also use them outdoors on a patio set or a deck chair. Since they're UV and water - resistant, they can withstand some sunlight and light rain, but it's a good idea to bring them inside during heavy storms. As for maintenance, a gentle vacuum can remove surface dust. If there are stains, spot - clean them with a mild detergent and a soft cloth. And remember, no assembly is needed, so you can start using them right away.
