Springfree Trampoline offers the SF90E which provides you with 113 ft(2) of edge-to-edge jumping surface. It's perfect for older kids, teenagers, and even adults! The huge polypropylene mat and 90 non-rusting, non-squeaking fiberglass rods give the SF90E an incredibly quiet and responsive bounce. It comes standard with a 6 ft FlexiNet safety enclosure, which gently cushions you if you land beyond the edge of the trampoline.
