<p>A trampoline including a flexible mat (1) and a plurality of resiliently flexible rods (2) the lower ends of which are retained in a frame (3) of the trampoline and the upper ends of which are coupled to the mat about a periphery of the mat to support the mat, in which the rod stiffness against bending is within the range of about 400 to about 1200 N/m and the rods are deflected at the upper ends of the rods, from a natural state of rest when the rods are in the position in the frame at their lower ends but before connection with the mat edge at their upper ends to connection with the mat, by between about 100 an about 300mm.</p> |
