Circular winter pool inflatable pillow designed to protect your pool cover and reduce water and debris buildup during the offseason. Key benefits Prevents water accumulation and leaf buildup: creates a stable cushion under your pool cover so rain and leaves stay off the cover surface instead of pooling. Reduces cover sagging: keeps the cover elevated and helps maintain proper drainage, extending the life of the cover and reducing cleanup in spring. Quick, simple setup: inflates rapidly with any standard pump so you can install it before covering the pool. Lightweight and portable: PVC construction is durable yet easy to carry, move, and store when not in use. What it is and how it performs Function: circular inflatable pillow that sits under the pool cover and acts as a barrier to pooling water and debris. Compatibility: designed to work with standard winter pool covers and standard air pumps for fast inflation. Material: durable PVC for reliable performance and easy maintenance. Sizes and thicknesses: choose the diameter and thickness that match your needs — available in 120 cm and 150 cm diameters; thickness options include 18 mm, 0.27 mm, and 0.30 mm. Practical applications Inground pools preparing for winter: place the inflatable pillow at the center under the cover to reduce ponding and simplify spring opening. Aboveground pools with fitted covers: use the pillow to lift the cover and limit debris and water collection around the cover seam. Shortterm storm protection: deploy the pillow before heavy rain to keep cover integrity and reduce the amount of water to pump off later. Easy use and care Inflate with a standard pump, position beneath the cover, and check for air tightness. Deflate, fold, and store in a dry place when not in use. Lightweight PVC construction allows for simple handling and seasonal storage without special equipment.
