A baby exercise jumper is usually a suspended sling-style seat hanging from a spring and/or rubber cable that is clamped above a door frame. The baby bounces in the seat by pushing with their feet against the floor.
Child safety experts do not recommend baby exercise jumpers, as there is a high risk for children to fall or trap and pinch their fingers. Children may also experience developmental delays if they repeatedly spend periods of 15 minutes or longer in exercise jumpers. Experts recommend using a stationary play centre as a safer alternative for children to play with.
Children using an exercise jumper can suffer:
limb and head injuries after falling from the jumper if the laces snap under tension or if they are not securely fitted in and strapped into the harness
injuries to fingers if they become trapped or pinched in the springs and chains on the jumper
delays in learning to walk after spending too much time in the jumper.
