HappyBottom® Pool Pad can add years of life to a pool and its liner. Made from a special high density closed cell polyethylene foam, Happy Bottom Pool Pad cushions and protects the pool liner. HappyBottom® reduces the potential for liner failure due to punctures. It also acts as a barrier to keep corrosion causing elements in the soil away from the metal components of your pool. HappyBottom® acts as an insulator under the pool, reducing heat loss to the ground. Reduced heat loss can save energy and extend your swimming season. A smooth, easy to clean bottom and reduced indentations are just a few of the benefits of using HappyBottom® Pool Pad. Pool owners love the comfort and luxurious feel HappyBottom® provides when it is used under a pool liner.
