Bestway 12ft Steel Pro Frame Pool Set is a great family swimming pool specially designed to withstand the elements and provide splashing fun for many years to come. The 12ft pool is made out of rust-resistant, steel frames, which are locked together using 'T' connectors and 'C' clips. All the fittings have been specially designed to lock together with ease. The frames hold the heavy-duty, PVC and polyester 3-ply wall in place, whilst PVC flaps hide the 'T' connectors and 'C' clips to prevent rust and injury. Included with the above ground pool are a 48in ladder and water cleansing 530gal filter pump. The only tool needed is a screwdriver. Other accessories include a protective ground cloth and a cover to shield from falling debris. The above ground swimming pool comes with a set-up and maintenance DVD for your reference.
