Key benefits Protects your above‑ground pool during winter by lifting the cover to reduce the weight of rain and snow, lowering the risk of cover cracking and pool damage. Long‑lasting, weather‑resistant protection thanks to cold‑resistant material and reinforced construction. Secure fit that resists wind and movement so the cushion stays in place through storms and freeze–thaw cycles. Quick, reliable inflation and airtight seal for hassle‑ setup and dependable performance all season. Main features Function: Inflates under your winter pool cover to create a raised center that diverts rain and snow runoff away from the cover and pool walls. Material: Made from 0.4 mm cold‑resistant PVC for reliable performance in low temperatures. Reinforcement: Thickened elastic band for improved tear resistance and double‑stitched, all‑round seams to minimize air leaks. Stability: Equipped with 4 m strong ropes and ‑quality silicone corner rings to secure the cushion to the pool and ensure a weatherproof fit. Inflation: Heavy inflation valves allow fast fill with an electric pump; the valve system and construction provide a good seal to reduce air loss. Compatibility and performance Designed for use with above‑ground pools and their winter covers as an essential winter accessory. Built to resist cold weather and repeated seasonal use without losing shape or causing air leaks, when used and stored according to normal pool winterization practices. Practical use scenarios Heavy snowfall: Place the cushion under the winter cover before storms to prevent snow buildup from sagging the cover and transferring pressure to the pool walls. Prolonged rain periods: The raised center diverts pooled water off the cover, reducing the chance of water weight causing tears or deformation. Freeze–thaw cycles: The cold‑resistant PVC and reinforced seams help the cushion maintain inflation and protect the cover when temperatures fluctuate. Quick setup and care Inflate using an electric pump via the heavy inflation valves for fast setup; ensure valves are closed tightly to maintain pressure. Use the 4 m ropes and silicone corner rings to tie and secure the cushion to the pool frame or cover attachment points. Inspect seams and elastic band before installation; patch or if any damage is found to preserve airtight performance. What this product delivers A practical, durable air cushion that reduces cover stress, protects the pool structure, and simplifies winter pool protection without complicated installation.
