Have loads of fun in your backyard with your family and friends in this Bestway Steel Pro swimming pool. The extra-strong side walls of this swimming pool are made with Tritech, a 3-layer reinforced material that consists of laminated heavy-duty PVC and a polyester mesh, which makes the side walls extra-thick, offering superior strength and durability. This above-ground pool has a corrosion-resistant steel frame. Thanks to the built-in flow control drain valve, it is easy to discharge the water. The above-ground pool can be set up quickly and easily. Simply lay the pool down on a flat surface, install the whole frame and then fill the pool with water. It is also easy to fold away the swimming pool for storage or transport.
