These covers did an excellent job of protecting our outdoor patio set last winter. These covers are very thick with good stitch quality. They have strong loops to hook around the legs of the furniture to keep them in place. We had plenty of snow and I want our set to last as long as possible. We just put them on the furniture for the winter. The only downside is that the canvas dips down in the center and collects rain and snow. You can place something sturdy and tall under the canvas in the center to keep this from happening. We just go lift the canvas to dump out the water.
