Vinyl Playsets


Swing Kingdom PlayetsSwing Kingdom Swingsets

Swing Sets

Our premium, vinyl playsets are five times stronger than traditional, wooden playsets. With accessories that range from infant swings to clubhouses, Swing Kingdom designs playsets that grow with your family. Therefore, each vinyl playset is manufactured with an eye towards durability and each set includes a 20 year warranty to stand behind our product.

Swing Kingdom's playsets are engineered from a safety first perspective. Our slip resistant, vinyl clad construction materials are always splinter free. And, no exposed wood means no harsh, annual chemical treatments. Stainless steel hardware and corner brackets bring added stability, while optional bars and rails allow for age-appropriate customization.

Childhood is a time for lively imaginations and spirited adventures. It is also the time to build a strong foundation for active and healthy lifestyles. Swing Kingdom's playsets combine the fun of childhood with the fulfillment of physical and developmental needs to deliver upon learning through play. The healthy habits that are fostered by enjoyable exercise may be the one thing more durable than our vinyl playsets.
