This trampoline comes with a slip-resistant jumping surface and easy grip handle bar to ensure both safety and fun. It is suitable for indoor and outdoor use due to its tough weatherproof mat, tubular steel frame, and durable coat finish. For extra safety, a padded cover around the mat cushions the frame and prevents children from stepping through the bungee cord. The trampoline is also ASTM safety approved and is CPSIA compliant. Adult assembly and supervision is required.
