Size:1460*480*680mm 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. Kids love our 4-seat Spring Bouncer because they can bounce at their own pace. This unit is not a teeter-totter. Each spring seat acts independently, which allows one child to bounce alone, or up to four at one time. Can be used by up to four children. Four comfortable seats with a small back surround the centre. Children can work together to rock back and forth, developing strength and coordination. This spring rocker also promotes teamwork!
