UIRWAY 500D Pool Cover 18FT Round [2026 Upgraded Heavy Duty Fabric] Solar Pool Covers for Above Ground Pools, New Super Windproof Gel-Coated Tarp Straps, Swimming Pool Covers with UV Protection

Word. Not sure what size or shape it is but this is the cover I use for my 18ft circlular pool. https://a.co/d/01T3in70 It stretches over the entire pool and sides. It's been such a relief not cleaning it daily from leaves and bugs. Also keeps the water very warm. The other day it was 86 degrees on a 94 day. Can't recommend enough for a good pool cover.
