Winner of a National Parenting Center Seal of Approval, this is the pogo stick that provides a stable platform so children can spend more time jumping and less time falling off and re-mounting. Modeled on the arched leaf springs used in truck suspensions, the jumping stick's patented "T-springs" put more surface area in contact with the ground, making it easier to balance on than traditional pogo sticks. The opposing semi-elliptical springs also provide superior bounce while allowing greater directional control. A wide, high-traction base prevents feet from slipping even during exuberant jumping. The bottom surface is a non-marring rubber-like material that won't mark floors or driveways. The aluminum shaft adjusts to three heights to accommodate riders of different statures. For ages 5 and up, 66-132 lbs. 45-58" L x 13" W x 10 3/4" D. (5 1/2 lbs.)
