We have an uncovered patio, and in Texas the weather and wind can be extreme. These covers fit, and cover our lounge chairs nicely. They are truly waterproof. They are exactly as described on line. Also I found customer service, when I called with questions were informative and responsive.

The only negative with the covers are the ties that secure the covers to the chairs. For me, they are not the quality that the covers are, and not easy to close.
