Swing (seat)
A swing is a hanging seat in a playground, for acrobats in a circus, or on a porch for relaxing.
On playgrounds, several swings are often suspended from the same metal or wooden frame, known as a swingset, 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.
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 (5m) above the ground, by "pumping," shifting their body weight to boost the height of the swing.
