This invention is directed to a combination stroller-infant seat which can be easily and quickly converted from one form to the other. The invention comprises a shell suitably shaped to hold an infant, a frame assembly for supporting the shell and retractable wheel assemblies on both sides of the frame assembly which facilitates converting from one form to the other. Each wheel assembly includes a vertically moveable central element, and a pair of wheels extensions pivotally mounted to the central element. To convert the apparatus to an infant seat, the central element is moved vertically causing the wheeled extensions to fold inwardly and then moved upwardly out of the way. To convert the apparatus to a stroller, the central element is moved downwardly so the wheeled extensions then extend laterally.
