All of our spring riders have been market-tested for years. Ride-on animals and spring bouncers are low to the ground (safe) , have foot rests and hand-holds, and appeal to small children and are inexpensive. These are made of Linear Low Density Polyethylene. This is a colorless, odorless, innocuous, recyclable plastic that is smooth and safe for the kids. This is for children 2 – 12 years old only.
