The Saturn 12ft trampoline is part of TP's new Planet Series. The octagonal frame provides a more controlled bounce over the entire jumping surface compared to circular trampolines that propel the jumper into the centre of the mat. It has a super safe surround that's made with strong flexible rods instead of hard steel uprights. All trampolines in the Planet Series have gold finished springs with excellent rust resistant qualities. They also have "intelligent feet" that can pivot to ensure the trampoline is stable when used on slightly uneven ground. The Saturn trampoline is easy to assemble and stores away in minutes, and the surround folds down when the trampoline isn't in use - so you can keep it all clean using the cover provided.
