A swing is a children's playground, which consists of a board or a seat attached to two ropes or chains, which in turn are attached to a crossbar or other support. Children can swing on the swing by moving back and forth using their feet or just pushing off the ground. Swings can be of various sizes and shapes, they can be installed both on playgrounds and in private courtyards. Swings are a popular children's toy that helps to develop coordination of movements, balance and muscle strength.
