Good item
Size: 15FT Round
Just purchased the 15 foot pad. I currently have a 12 foot pool and wanted something to keep my leveling sand in place. It helps to keep any foreign object from damaging the pool bottom. I would recommend getting one larger then your pool size. It's strong material then I thought.
