Protect your pool: Damage caused by freezing and expansion in winter can directly damage the walls and cover of your pool. Our winter pillow for above ground pools can rise slightly above the water surface to balance winter pressure and protect your pool from damage. Durable material: Our inflatable winter pool pillow is made of durable, puncture-resistant material, which can withstand harsh winter conditions and protect your pool throughout the winter, preventing leaks, cracks, or air loss. Easy to use: Using our inflatable winter pool pillow is very easy. The pillow is equipped with a valve for easy inflation. Simply use a household electric pump to quickly inflate it. Then attach a rope to the four loops on the edge and secure it in the middle of the pool. After use, it can be easily deflated for convenient storage and reuse. Versatile: This winter pool pillow reduces the accumulation of leaves, rainwater, melted snow, and dust in the pool and prevents the cover from collapsing. It can also protect your garden furniture by reducing water pressure on the covers and preventing the accumulation of water or snow.
