THICKENED & DURABLE: The pool pillows for above ground pools is made of 0.4mm thickened PVC material, which is cold-resistant, tear-resistant, and can easily handle the cold of -10°F (-25°C), and can also withstand up to 180°F (80°C) of heat to reliably protect your above ground pool
PROTECT YOUR POOL ALL WINTER: As water freezes and expands during winter, pool walls can crack due to stress. Pool pillows can absorb the pressure of the freezing process and protect your pool walls from winter damage. They can also prevent rain, snow and fallen leaves from accumulating in the middle of the pool, reducing the risk of pool collapse
SIMPLE SETUP: Inside the package, you'll find two 4x4 ft pool pillows and two 50 ft ropes. Pass the cut rope through the sturdy grommet and secure it to the pool, ensuring the pool pillow is positioned at the center of the water.
DOUBLE VALVE FOR EASY INFLATION: Our pool pillow specially adopts a double valve design, which is easy to inflate and deflate, and has stronger air tightness. The double-layered hemming process ensures it's leak-free and lasts all season long. Note: Inflate the pool winter pillow to 70-80% of its full capacity, to allow the pool pillow to expand and contract flexibly
FIRMLY FIXED: Our 4 pcs heavy-duty grommets are stronger than ordinary grommets, and no risk of metal grommets scratching the pool pillows for closing winter. The 50FT rope is the longest on the market, can be cut as needed, and is more flexible. Place the pool pillow for winterizing securely in the middle of the swimming pool, so that the pressure is evenly distributed
