A frame apparatus for a child's swing includes a pair of curved rear legs extending upwardly and forwardly to terminate in a pair of transversely spaced hanger housings that are positioned in a cantilevered manner from a support provided by a corresponding pair of curved front legs that extend upwardly and rearwardly to connect to mounting housings supported at a mid-point on the rear legs. The frame apparatus provides an open top, open side frame configuration for unrestricted access to and viewing of the seat. The front legs and the seat hangers can be detached from the rear legs to provide a compact storage and transport configuration for the swing. One of the mounting housings contains the battery array for the electric motor powering the swinging motion of the seat to position the batteries below and remotely from the seat. The frame members are oval-shaped to increase operating strength.
