A self-supporting pool is a type of above-ground pool whose structure consists solely of a flexible pool liner and an inflatable top ring. It gains its stability and shape only after being filled with water. The water pressure from the inside pushes against the walls and keeps them upright. No additional support structure is needed for installation; simply lay it out on a flat, solid surface, inflate the top ring, and start filling it with water. As the water level rises, the pool walls rise on their own. Thanks to this simple design, assembly and disassembly are very quick and easy, allowing for convenient storage outside the swimming season.
