A safe trampoline includes a flat resilient mat, and a support frame including an upper frame formed around the resilient mat and a lower frame for supporting the upper frame. The safe trampoline includes: a plurality of rollers mounted on the upper frame; connection members other than springs, sides of which are indirectly or directly coupled to a periphery of the resilient mat and opposite sides of which are partially wound on the rollers; and resilient bodies, sides of which are coupled to the opposite sides of the connection members and opposite sides of which are fixedly coupled to a specific part of a planar lower location of the resilient mat. The resilient bodies extend or are restored to the original positions according to a load applied to the resilient mat.
