A great trampoline! After 2 cheaper trampolines we got a JumpFlex, what a difference. Assembly was easy (no bolts!) and looks great. Kids love it. Definitely worth a bit more for this great product.

Protection from Mother Nature

As well as looking great in your backyard, Jumpflex™ 12 ft trampolines are designed to stand the test of time. Jumpflex™ metal components undergo a 6-layer rust-proofing and durability process.

All metal components are galvanised inside and out with a hard-wearing zinc coating. Visible sections are finished with a UV-resistant black powder coating. This ensures Jumpflex™ trampolines will remain a property feature you'll be proud of.
