The all-weather durable TrueBounce aluminum top means consistent bounce and play, indoors or out. Its construction means lighter weight and added strength, with snag-preventing corner pads and an aluminum apron and heavy duty steel chassis means extra stable play. The oval-shaped self-opening legs glide open at your touch. Move it in or move it out on 4-inch ball bearing mag wheel casters. It includes a weather-resistant net and posts, ready to set up and serve.
