A high-resilience mat over 36 strong springs gives this 7.3 ft trampoline the responsive bounce that keeps children coming back. A 56"-tall enclosure net surrounds the 65.5" x 62" jumping area, which sits 17" above the ground, and the galvanized steel frame stands up to outdoor conditions. ASTM certification confirms the build. Usable indoors or out, it suits children aged 3 and up with a 150 lb weight limit. Overall 7.3 ft x 7.3 ft x 6.1 ft; net weight 56.5 lbs.
