A combination vehicle seat and stroller for a child is provided with retractable wheel assemblies which forms a substantially flush, smooth bottom surface which will minimize damage to the upholstery of the vehicle. The apparatus is provided with a handle which is retractable when the apparatus is used in a vehicle seat mode, and deployable for use as a stroller. A coupling system is optionally provided for deploying and retracting the wheel assemblies in response to the deployment and retraction of the handle. Forward ones of the wheel assemblies are arranged to pivot so as to provide a steering capability to the stroller, and may be longer than the rear wheel assemblies so as to provide a reclining attitude for the child.
