Pool pillow for winterizing — cold and UVresistant PVC construction that protects your pool cover and pool edges during freezing weather. Key benefits Built to resist freezestress: Thick, coldresistant PVC construction reduces the risk of edge cracking and maintains shape in low temperatures. Holds covers in place: Windresistant design plus an integrated doublerope retention system keeps the cover secured and minimizes shifting during storms or windy conditions. Shields from frost and debris: Acts as a buffer between the cover and ice or snow, conforming to curved pool edges for better coverage and helping limit debris intrusion. Longer service life: UV and coldresistant PVC layers increase durability, reducing the need for frequent replacements and simplifying offseason pool care. What it does Prevents pressure and edge damage by absorbing freeze expansion beneath the cover. Keeps pool covers stable with a proven doublerope securing method to reduce sagging and cover movement. Conforms to pool contours to improve overall coverage and reduce debris accumulation under the cover. Compatibility and material Made from coldresistant, UVstable PVC layers for reliable outdoor performance. Designed to fit under standard winter pool covers and to conform to curved pool edges for effective sealing and protection. Practical use scenarios Fall winterizing: Place the pillow under the cover before the first freeze to reduce ice pressure on pool edges and extend cover life. Lateseason storms: Use the pillow to stabilize the cover and limit debris entry during windy, snowy conditions. Extended storage or offseason care: Keep the pillow in place throughout the offseason to reduce cover wear and maintain cleaner water at opening. Installation and care Position the pillow beneath the cover at the pool center where ice expansion is most likely, and secure using the pillow's doublerope system to prevent movement. Store in a dry place when not in use to preserve PVC layers and prolong service life.
