I bought these covers for my patio furniture tables, chairs, hot tub, and chaise lounges) to protect them for the winter. They are very attractive, the color slate is what drew me in to buy them because it is an unusual color and is very pleasing to look at on the deck during the winter. I also purchased them because the were touted as being 100% waterproof. Well, they are not and I discovered that in the nick of time. I covered my sofa set with the cushions on because the cover was supposed to be 100% waterproof. Good thing I checked to see after the first torrential Autumn downpour. My cushions were soaked. I had to bring them in and put them in my basement to dry. As I say, they are a very pretty color and they serve as adequate protection against the elements,eg. dirt etc., however they ARE NOT waterproof. If that is what you need, I would not recommend these.
