A resilient object adapted to be ridden by a person sitting or standing thereon and exerting repeated jumping motions thereagainst. In one embodiment, the device comprises a resilient body member having an upper seat portion and a lower bottom portion, a handle member attached proximate its seat portion, and foot supports extending from either side of its lower portion. The device is ridden by a rider sitting on the seat portion with his legs astraddle the body member, grasping the handle member and exerting repeating jumping motions against the foot supports to bounce the device across the ground. In a second embodiment, the device comprises a horizontally oriented resilient body member having an overall width dimension substantially greater than its heighth dimension, and including a pair of foot supports attached to its upper surface for engaging the feet of a rider standing thereon. This latter device is ridden by a rider standing on the upper surface of the body member, with his feet engaged by the foot supports, and jumping up and down to bounce the device across the ground. In either embodiment, the body member may be filled with a resilient material or be substantially hollow and inflatable. A reinforcing layer of resilient material is provided over the lower surface of the body member to protect it from damage caused by repeated contact with the ground as the device is ridden.
