Pool Mate Ice Equalizer Pillow

As water freezes and expands, it creates immense pressure against your pool walls and cover. The pillow acts as a compression point, absorbing that expansion force so the stress is directed inward toward the pillow rather than outward against your pool walls or upward against the cover.

This specific model is designed exclusively for above-ground pools. It is intended to sit under the pool cover to manage ice expansion in that specific environment.

You should inflate it until it is firm but not rock-hard. Filling it to about 70% to 80% capacity is usually ideal, as this leaves enough room for the air to compress when ice forms without putting undue strain on the vinyl seams.

For smaller above-ground pools, one 4 ft. x 15 ft. pillow is often sufficient. However, if you have a larger pool, you may need to connect multiple pillows to ensure adequate coverage and pressure relief across the entire surface area.

Most users secure the pillow by tying a rope through the grommets on the pillow and anchoring it to the sides of the pool wall. This prevents it from drifting to the edge of the pool where it would be ineffective.
