Using your Christopher Knight Home® Santa Ana Club Chair Set is simple. Just assemble it following the included instructions and place it in your outdoor area. When it comes to the cushions, since they're water - resistant but not waterproof, if it starts to rain heavily, it's a good idea to bring them indoors or cover them. For regular cleaning, you can use a mild soap and water on the cushions and the wood frame. The wire - brushed finish on the wood makes it easy to wipe away dirt. If you notice any loose parts over time, check the assembly instructions and tighten them up. With proper care, these chairs will serve you well for a long time.
