"The Power Steel™ Swim Vista Series™ II from Bestway® is the second generation of the world's first frame pool with integrated portholes, offering a truly unique pool experience. Integrated portholes: Thanks to the reinforced portholes integrated into the side walls, swimmers have the necessary view even underwater. These parents also offer improved supervision options. And because no additional tools are required, assembly is really child's play. Durable Construction: The corrosion-resistant steel frame is equipped with our proven Seal & Lock System™. This ensures a stable and secure connection of the individual elements. The connectors effectively prevent damage and rust-causing metal-to-metal contact. The durable steel pool legs have up to 17.5% more bending resistance than comparable pools. The pool liner is made from our 3-layer TriTech™ material. This is up to 15% more tear-resistant, 33% more stretch-resistant and 83% more puncture-resistant than traditional PVC. Scope of delivery: The set also includes a sand filter system, safety ladder, tarpaulin and a ChemConnect™ chemical dispenser. The ChemConnect™ chemical dispenser ensures clean, healthy pool water by distributing just the right amount of chlorine evenly throughout the pool.
