Make swing time even more fun by turning it into bounce time. This bounce adapter fits most indoor suspension swing brands, adding a new dimension of vestibular challenge. This is a purchase of only the pair of Bounce Adapters. Swing not included. The Bounce adapters are suitable for 30-70 lbs each. Note that too much weight will affect the springs ability to bounce, and too little weight will not be enough to make the spring bounce. Child can bounce while swinging back-and-forth. Bouncing is not only fun for kids, it's healthy. Bouncing lightly works the muscles in the legs while being easy on the joints. The device is easy to attach and remove.
