>BIGGER IS BETTER!!! Just take a look at this trampoline. It features the largest jumping surface of any rectangular trampoline on the market; a huge 168 sq. ft. of permatron jumping mat. The woven permatron jumping surface has 750 lbs. of bursting strength for maximum bounce (400 lbs. maximum weight limit). The Extreme is built to last a lifetime, and easy to assemble, with an 11 gauge galvanized steel frame and 8 1/2" heavy duty ultra bounce springs. The springs and frame are also completely covered with heavy duty pads made with 18oz. weather resistant vinyl on both sides, which makes them reversible for "twice the life". Only the best USA made materials are used, and for added safety, a Net Enclosure is available.
