A foldable trampoline includes a tubular frame having a first section and a second section coupled to each other via a pair of frame hinges. The device further includes a flexible fabric stretched outwardly attached to the tubular frame to form a trampoline mat, wherein the tubular frame is configured to in an unfolded position or a folded position via the pair of frame hinges. When the tubular frame is in the unfolded position, the first section and the second section are laid out flat away from each other via the frame hinge to form a full-pie shape. When the tubular frame is in the folded position, the first section and the second section are folded towards to each other via the pair of frame hinges to form a half-pie shape, without having to remove the flexible fabric from the first section and second section.
