The set of 2 pool cushions is the ultimate must-have for any pool in winter. It protects your pool from ice during the winter months by keeping water off your pool cover. The pillow also ensures that your cover does not freeze to your pool water during the winter season. This cushion is made of sturdy PVC, making it durable for garden use. When inflated it measures 110 x 110 cm. The cushion pushes your pool cover off the water surface, preventing water from freezing to it.
