A spring-actuated swing device. The spring-actuated swing device includes a seat having a receiving surface, at least one line, each of the lines having a bottom connecting point removeably attachable to the receiving surface and having a top connecting point removeably attachable to a support beam, and at least one spring mechanism. Each of the spring mechanisms is removably attachable to at least one intermediate connecting point of each of the lines intermediate the receiving surface and the support beam, and each of the spring mechanisms displaces a portion of each of the lines. The spring mechanism includes either a compression, stirrup or extension spring, and may also include an emergency strap. A method for producing swinging and/or bounce in playground, athletic or recreational equipment using the spring mechanism is also provided.
