Abstract: A stairway step assembly for use as an aid in climbing a stairway. The assembly is particularly useful to elderly and handicapped users who have difficulty climbing a standard stairway due to the height or rise of the steps thereof. The assembly provides a means of quickly, economically, and safely altering the step arrangement of the standard stairway with minimal or no modification to the permanent structure of the stairway. The assembly comprises a plurality of step members having predetermined horizontal dimensions and a predetermined height which is approximately one-half the height or rise distance of a standard step. The assembly further comprises an attachments mechanism for connecting the step members in place on the top or horizontal section of standard steps.
