consists of a metal frame supporting the spring bed that the gymnasts bounce off to perform their routines. The trampoline is 5.05 metres long, 2.91m wide and 1.155m high. The bed is made from nylon or string material and is only about six millimetres thick.
A large, thick mat, known as the safety platform, sits on the floor at each end of the trampoline. It is designed to cushion the impact if anyone falls from the trampoline.
Men and women may compete in socks or gym shoes.
