These Valdez side chairs are great for both indoor and outdoor use. To use them, simply place them where you need seating. When not in use, since they are stackable, you can stack them up to save space. For maintenance, if you're using them outdoors, make sure to store them inside or cover them well to protect them from the elements. Don't let any part of the chair, especially if there's wood, sit in water. It's a good idea to dust the chairs regularly using a small brush or a vacuum cleaner. And if you spill something on the chair, quickly wipe it up with a slightly damp sponge to prevent stains.
