The Winter Pool Pillow serves as a crucial accessory in safeguarding your above-ground pool during the frigid months. Expertly made with cold-resistant PVC, it offers a robust defense against freezing conditions, withstanding temperatures as low as -20°C. The round shape perfectly complements your pool's form, creating a snug barrier between the water surface and the cover. Thanks to the integrated Boston valve, the pillow inflates rapidly, requiring only 70%-90% inflation to function effectively. This attribute protects the material integrity and ensures a secure, lasting seal. Besides providing efficient cold resistance, the pillow boasts substantial UV protection, allowing it to endure constant sunlight without degrading or fading over time. The thoughtful addition of eyelets and nylon cords guarantees the pillow stays positioned even during strong winds or under heavy snow loads. This accessory delivers comprehensive outdoor protection, proving essential for pool owners seeking convenient and reliable maintenance solutions. Whether preparing your pool for winter or maintaining it throughout the season, its amalgamation of practicality and engineering ensures your pool remains safeguarded and well-maintained. vidaXL Size: 180cm H x 310cm W x 310cm D
