Every day is a fun day when your baby is in the bumper jumper! Your baby will squeal with delight while the strong bounce spring with enclosed safety cord helps him have the time of his life! You can adjust the height as your baby grows so the fun is not over too soon. Moms will love the fact that the spring loaded clamp does not ruin door molding . When you take the jumper off you will never remember you had it there if not for your baby's fond memories.
