Swing (seat)

A swing is a hanging seat, often found at playgrounds for children including adults, at circus for acrobats, or on a porch for relaxing, although they may also be items of indoor furniture, such as Latin American hammock or the Indian oonjal. The seat of a swing may be suspended from chains or ropes. Once a swing is in motion, it continues to oscillate like a pendulum until external interference or drag brings it to a halt. Swing sets are very popular with children.

On playgrounds, several swings are often suspended from the same metal or wooden 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 a wooden plank suspended on both sides by ropes from a tree branch.

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 swing sets, 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. The flat version 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.

Natural swings may be created by lianas (creeper plants) in a subtropical wild forest like Aokigahara forest near Mount Fuji.
