Ice and frozen water can cause potential damage to your above ground pool cover and pool walls due to expansion. This 16-gauge vinyl Air pillow goes under your pool cover, and protects your pool cover and walls by attracting freezing water as it expands due to water contraction. This multi-purpose pillow also helps reduce the build-up of rain, leaves or snow on your winter cover. The Air Pillow only needs to be inflated halfway to prevent deflating due to expansion.
