A collapsible stair cover, comprising:
- a first length of stair covering material substantially impervious to liquid, and having top and under sides;
- a plurality of individually spaced step-upon treads secured to said top side of said covering material;
- a plurality of individually spaced non-skid, non-slip surfaces secured to said under side of said stair covering material;
- and with said stair covering material having a resistive strength to withstand the weight of a person walking thereon, and a flexibility to fold between adjacent ones of said individually spaced step-upon treads;
- and
- wherein said stair covering material is of a flexibility to fold adjacent ones of said individually spaced step-upon treads substantially flat one atop another for storage and to unfold said adjacent ones of said step-upon treads vertically offset with respect to one another when draped down for covering a set of stairs.
