Spiro Bouncer: The spinning, bouncing, bobbling seesaw for 2-5 year olds that can be used indoors or outside. This advanced seesaw bounces up and down and spins 360 degrees. The soft ball cushions maximize bounce and minimize impact. Includes a blow-molded base that can be weighted for additional stability. The Spiro Bouncer develops strength, coordination and balance. The Spiro Bouncer is designed to support a maximum of 55 lbs weight at each end.
