Protect the swimming pool: The cold outdoor weather in winter makes the swimming pool water freeze, our swimming pool cushion can help you disperse the pressure of the ice on the pool wall. It is recommended to inflate the swimming pool cushion to 70% to make room for the expanding ice, which avoids frost that can damage the swimming pool. If you cover the swimming pool with a dust cover, it also prevents snow or rain from accumulating in the middle of the pool cover so that the pool cover does not collapse. Quality material Superior: The pool cushion is designed with a double seal, which makes it less likely to be specially designed for cold weather in winter and is a great companion for your swimming pool Fixing Cable Included: The pool cushion has 4 holes on the edges that can be fixed in the center of the pool with the 15m cable. This ensures that the inflatable cushion does not move in the water and that the pressure of the ice cubes on the pool is evenly distributed when it freezes. When using the pool cover, the pool cushion in the middle of the pool can play a good role in drainage and snow prevention. Easy to use: This inflatable pool cushion is very easy to use. Just use the electric air pump commonly used in the family to quickly inflate. Then tie the ropes to the four holes on the edge of the pool cushion and fix them in the center of the swimming pool. You can install it easily and quickly in ten minutes. Tips: This product does not contain an air pump. Please do not overfill the inflatable cushion.
