Your kids will love jumping on the Skywalker Trampolines 14' Rectangle Trampoline with Enclosure, which features a 14' x 8' rectangular design with a galvanized steel frame. Welded T-sockets eliminate frame twisting, and the jumping mat is made of heavy-duty, UV protected polypropylene for strength and durability. The enclosure netting provides increased safety, while extra-wide, UV-protected, vinyl safety pads cover the frame and springs. Eighty large, 7" springs and four 5.5" springs provide great bounce.
