Heavy duty trampoline built by trampolineworld.com; not a cheap Walmart version. Frame and springs are heavy duty galvanized steel. Heavy duty jumping surface is 11 feet 6 inches Pad area is 1 foot. Total diameter is 13 feet 6 inches. I bought this for my kids for over $2,000 years ago and went for this heavy duty one as I wanted it to last. Springs and frame are in very good condition. One tiny hole on the jumping surface. The pads are worn but they're still functional. Hopefully you can enjoy as much as my family did. It will require dis-assembly by a couple people and likely a truck.
