Will only last about one season. For the first season, the covers looked nice and seemed to work well. The buckles are nice. We purchased our covers in May of 2018, used them that summer, and then took them inside for the winter. During the summer of 2019, we found that the covers were no longer waterproof (our furniture was all soaked), and that the PVC backing would melt onto itself in the sun if the cover was folded over at all (e.g. at the bottom edge). In addition, the fabric became brittle and tore in several places where chair backs stick up.
Thank you very much for your support and feedback on our products. We will study it immediately,Have a nice day! Thank you.
