Bestway 15ft Steel Pro Frame Pool is a great family swimming pool specially designed to withstand the elements and provide splashing fun for many years to come. The 15ft 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. The above ground swimming pool comes with a set-up and maintenance DVD for your reference.
