This ASTM-approved 8 FT outdoor recreational trampoline for kids and adults adopts curved net poles, which create ample safety space to avoid injury. The springs are covered with a safety pad so that kids will not hurt their feet if they step on it. Furthermore, the enclosure net is crafted of high-density and tear-resistant PE, and its connection between net poles is well assured. You can enjoy deep bouncing and fast rebound thanks to the highly resilient jumping mat and springs. The overall frame is constructed of double-sided galvanized steel pipes and the leg tubes are added with paint coating. Hence, this outdoor trampoline is highly rustproof, wear-resistant, and weather-resistant. The assembly is easy just with detailed instructions and installation tools.
