en frame, known as a swing set, allowing more than one child to play at a time. Such swings come in a variety of sizes and shapes. For infants and toddlers, swings with leg holes support the child in an upright position while a parent or sibling pushes the child to get a swinging motion. Some swing sets include play items other than swings - such as a rope ladder or sliding pole.

For older children, swings are sometimes made of a flexible canvas seat, of rubberized ventilated tire tread, of plastic, or of wood. A common backyard sight is of a wooden plank suspended on both sides by ropes from a tree branch. Older children can go much higher, sometimes over 15 feet (5 m) above the ground. In the United States, some adults go to the extreme and compete in the NSA, "National Swing Association", where competitors reach heights over 20 feet, while leaping at the peak of their swing.

Types of swings

Tire swings are a form of swing made from a whole tire. These are often simply a new or used tire hanging from a tree on a rope. On commercially developed playground swingsets, oversized new tires are often reinforced with a circular metal bar to improve safety and are hung on chains from metal or wooden beams. They may hang vertically or hang flat, suspended from three or more points on one side. These flat type of swings can hold three or more children. Pumping is achieved by using one or two of the three chains attached to the swing, and two (or more) children can pump in turn. Tire swings can also be used in spinners, where the occupants use their feet to propel the tire. Children find ways of performing dangerous stunts on tire swings, and because of this, many have been removed from schools and parks.

Rope swings are swings created by tying one end of a length of rope to a tree branch, bridge, or other elevated structure. A knot or loop is usually put on the other end to prevent fraying and help the swinger stay on. Rope swings are often situated so that those swinging on them can let go and land in water deep enough to cushion the fall and to be swum around in.
