A device for assisting a medical walker user in transitioning from a sitting position to a standing position as the medical walker user attempts to access the medical walker because the device incorporates a platform base which becomes stabilized by placing the weight of the medical walker user on the platform base which in turn stabilizes the medical walker via each automatic movement restrictor assembly (AMRA) attached to the platform base because each AMRA automatically engages/captures each of the medical walker's two front axles as the medical walker's two front wheels impact each of the two AMRAs additionally such that the device will automatically move from a position of engagement with the medical walker's two front axles to a position of disengagement with the medical walker's two front axles when the medical walker along with the medical walker's two front wheels leave/exit the device's AMRAs.
