Abstract: A three dimensional stringer pad affixed to the stringers of a staircase prior to applying carpet. The stringer pad is dimensioned to substantially completely overlay the stringer, has an inner flat surface which lies substantially flush on the stringer and has an outer surface which billows out from the stringer to create a three dimensional surface upon which carpet is later applied. Prior to applying carpet to the stringers of the staircase, the three dimensional stringer pads are applied to the stringers using nails or any suitable adhesive. Carpet is then applied to the stringers with the stringer pads interposed between the carpet and the stringers. Due to the billowing surface of the stringer pads, the carpeted stringers are provided with a three dimensional look which is aesthetically pleasing and which serves to further define the risers and treads of the staircase. Preferred aspects of the invention include constructing the stringer pads from inexpensive polyurethane foam or equivalent material.
