Key benefits Thick PVC material provides durable, enduring use and resists sun, snow, and leaves. Inflates and deflates quickly for fast setup and removal. Simple secure attachment using the included rope threaded through reinforced eyelets to tie the cushion to your pool. When used under a pool tarpaulin, it pushes the cover off the water surface to help prevent freezing on the cover. The cushion helps distribute surface tension, protects the pool wall, and reduces accumulation of rain, snow, and leaves on winter covers. How it works Inflate the cushion quickly and use the included rope and reinforced eyelets to securely attach it to your pool. Place the cushion under the pool tarpaulin so the cover sits above the water surface rather than directly on it. When the season ends, deflate for easy storage. 23 use scenarios Winter pool closure with tarpaulin: place the cushion under the cover to lift the cover off the water and reduce freezing buildup, while protecting walls. Seasonal cover maintenance: use the cushion to keep covers dry and from debris by elevating the cover above the water surface. After weather events: during rain or snowfall, the cushion helps minimize water contact with the cover and supports easier removal when you reopen the pool.
