Forms a pyramid to let water run off cover. It floats on top of the water under the cover and also prevents damage due to ice expansion. For all above-ground pools. Made of heavy gauge vinyl and is easy to install.

Does not hold air
Pillow inflates easily, however does not hold air. Within 24hrs the pillow was almost completely out of air. Would not recommend this product.

Rope not included.
Pillow DOES NOT include rope like a previous review says. Seems kinda thin but we will see. Will update review after winter season.

Does the job
This pool pillow has a rope attachment, which is good for holding the pillow in the middle of the pool. It was easy to inflate waith an electric pump.
