Jolly Jumper, the original baby exerciser, has just been improved! The new model comes with a Super Stand which provides ultra-bounce via the new premium spring action! This jumper can be used indoors and outdoors with NO doorways needed! When not in use, the unit folds flat, allowing for easy and quick storage. The Jolly Jumper will help your baby improve balance, develop rhythm & coordination as well as strengthen their muscles. The saddle is designed to fit your baby like a second skin, similar to the fit of surgical back support or weight lifter's belt. Most imitations of our exerciser do not provide this type of support! The Jolly Jumper Exerciser is sturdy & scientifically designed, allowing baby to enjoy healthy exercise from as early as *3 months (*if baby can hold head up with full neck support) to walking age with a maximum weight of 13 kg or 28 lbs. Your baby will build strength, balance & coordination safely & comfortably with Jolly Jumper! No tools required for assembly, which is quick and easy.
