The amazing, graceful Swan should be in all playgrounds. Children seek it out to rock and play again and again. The Swan is truly universal design: the back, calf and foot supports, the shelter of the seat sides and the vertical handholds make it accessible and usable for all. Children rock the Swan using their leg, arm and core muscles to coordinate movements and set it into motion. Alternatively, the spring will move when children stem their back into the seat, without using leg muscles. The handholds support a relevant grip height for all. Rocking the Swan supports the senses of balance and space that are fundamental for body confidence and movement control. The springer’s response to movement builds an understanding of cause-and-effect. It supports logical thinking, a fundamental cognitive skill.
