Up to four children will enjoy bouncing on the Spring About. With safe, individual springs on each of the four spokes, children can mount and dismount with ease, while not interfering with any of the other riders. The Spring About operates on a ball bearing system and has versatile installation options. You can choose between a surface mount unit or an inground mount unit. Three bright colors are available; red, blue, and yellow. Color coordinated dots decorate the center of the unit. The Spring About is designed for children ages 2-5 years and is an important tool in developing social interaction.
