A rocking chair or rocker is a type of chair with two curved bands (also known as rockers) attached to the bottom of the legs, connecting the legs on each side to each other. The rockers contact the floor at only two points, giving the occupant the ability to rock back and forth by shifting their weight or pushing lightly with their feet. Rocking chairs are most commonly made of wood. Some rocking chairs can fold.Rocking chairs are often seen as evocative of parenting — as the gentle rocking motion soothes infants and sends them off to sleep.Many adults find rocking chairs soothing because of the gentle motion. Gentle rocking motion has been shown to provide faster onset of sleep than remaining stationary, mimicking the process of a parent rocking a child to sleep.Varieties of rockers include those mounted on a spring base (or platform) called platform rockers and those with swinging braces commonly known as gliders.This is made in zbrush and it is used for 3d printing only.
