A foldable trampoline including a resilient web, a web frame assembly and a plurality of springs includes peripheral frame members pivotally connected t o each other such that the web can be positioned between a first position oriented in an approximately horizontal configuration forming a trampoline, and a second position where a portion of the web is oriented at an angle of less than 180.degree. relative the other portion of the web to thereby form a backstop for ball games. Frame assembly members dampen the movement of the frame members relative to each other to thereby control the rate at which the trampoline is folded.
