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.^[1][2] Rocking chairs are most commonly made of wood. Some rocking chairs can fold.

The word rocking chair comes from the verb to rock.^[3] The first known use of the term rocking chair was in 1766.^[4]

Rocking chairs are often seen as evocative of parenting, as the gentle rocking motion soothes infants and sends them off to sleep.^[5]

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.^[6]

Rocking chairs are also comfortable because, when a user sits in one without rocking, the chair automatically rocks backward until the sitter's center of gravity is met, thus granting an ergonomic benefit with the occupant kept at an un-stressed position and angle.^{[citation needed]}. Rockers are also good to use during pregnancy as it reduces back pain and promotes relaxation and stress reduction.^{[citation needed]}

Varieties of rockers include those mounted on a spring base (or platform) called "platform rockers" and those with swinging braces commonly known as gliders.^{[citation needed]}

By the 1950s, rocking chairs built by Sam Maloof, an American craftsman, became famous for their durability and deluxe appearance. Maloof's rocking chairs are distinguished by their ski-shaped rockers.^[9]

Peter Cooper, an American industrialist and inventor, designed an iron-frame chair with a functional, minimalist design radically different from Victorian heavily decorated, ostentatious designs. At that time most rocking chairs had separate rockers fixed to regular chair legs, Cooper's chair used the curve of its frame to ensure the rocking motion. Coopers chair was made of steel or wrought iron with upholstery slung across the frame. Cooper's model was manufactured at R.W. Winfield & Co. in Britain. The firm exhibited examples of the chair at the Great Exhibition of the Works of Industry of all Nations (Crystal Palace Exhibition) in 1851 and the Great London Exposition of 1862.^[10]
