Four different styles of the Playmotion Riders by Sii stay close to the ground as children ride waves in the safety of the playground. Each of the styles is designed to resemble different types of surf boards, giving children the feeling of soaring over the water. Each style is brightly colored to draw children to play. The Playmotion Riders help to develop core strength, balance, and coordination. The play surface is soft textured and coated for non-skid safety.
