90" Outdoor Square Table & Chair Cover with Integrated Duck Dome - Duck Covers: Water-Resistant Polyester Furniture Protector

Works fantastic and is made strong. Have it on my spa to protect it from the sun . It fully covers the top and all 4 sides works great nice price $$$ quality built 👌 Ok

These products are good quality covers. I saw a lot of people complaining it is not waterproof but I assure you this is almost certainly due to allowing pools to sit on low spots. When the cover is on and there are no low spots, the stuff under these covers does not get wet. I guess you would say they are highly water resistant, as water must sit to penetrate. This is good though, as it allows breathability, and helps prevent mildew. I got two different covers and they both come with a duck dome, which you fill with a pump pretty quickly and it prevents pooling because it makes a bubble that eliminates low spots. I built a big deck and bought new nice outdoor furniture, so these covers are a must, and they do the job well.
