You must place a pool pillow under your winter cover to protect your above ground pool walls from the added pressure of rain, snow and ice accumulation in the off-season. As your pool freezes in winter, the pool pillow allows ice to expand inwards, instead of out towards your walls. Use it along with the Pool Pillow Pal to help it stay in place all season!
- Pool walls are relieved from water expansion
- Inflate the air pillow half-way
- Ideal for above ground pools
- Protects and keeps water-off of your pool cover
