Patio Furniture Covers

Last summer we purchased some new patio furniture. It is a rod iron type of furniture. We are very pleased with it and would like to have it around for a long time to come. The only thing is the cushions are wearing due to the weather and the direct sun. I think we had better start looking around for some patio furniture covers. I know others that use that type of thing. It would help save on the lifetime of the cushions.
