Usually made of heavy-duty vinyl, air pillows are a necessary addition when winterizing your above ground pool. An air pillow, also known as an ice compensator, goes underneath your winter pool cover to help prevent the freezing and expanding winter pool water from cracking and damaging the walls of your above ground pool. Air pillows offer the additional advantage of reducing the amount of water, snow, and debris that collect on your winter cover.
Air pillows for above ground pools are very reasonably priced and are worth every penny if it means saving your pool from winter ice damage.
