Abstract: A portable, foldable swimming pool step device includes a pair of sectional stiles interconnected by transverse steps and provided with sectional handrail structures. The stiles, steps, and handrail structures are formed of a thermoplastic material. Each stile includes a pair of sections hingedly connected together and foldable between an extended operative position and a folded position. The steps are adjustable to permit the swimming pool step device to function as an inclined ramp. Suitable rollers are mounted on the stiles to permit easy movement of the swimming pool step device when the ladder is in the folded position.
