  • a stair mat comprising: a tread base sheet member adapted to be fixed on a tread having at its front edge an edge covering bead adapted to cover the forward edge of the stairs; and a tread mat adapted to be fixed on the tread base sheet member so as to be adjacent to the edge covering bead.
  • the tread mat can be easily and firmly fixed on each step, is free of undesirable dispersion, and can be easily changed according to the extent to which it is worn out, damaged, dirty, and the detached tread mat can be washed.
  • the stair mat protects the forward edge of the step, and gives effects of non-skid and cushioning, further gives sound absorption, thermal insulation, flexibility and ornamentality.
  • the stair mat can alleviate the problem of missed footing on the stairs and obviate the danger of missed forrting.
  • the stair mat is economical and suitable for the stairs, and can diminish the quantity of carpet required.
  • a stair mat of the present invention may include a framing bead at the rear edge so as to form a tread mat securing area between the edge covering bead and the framing bead, the tread mat being installed on the securing area.
  • the edge covering bead and the framing bead may each be provided with an inclined abutment surface or a securing groove, so as to cover the front and rear edges of the tread mat. This arrangement can prevent fraying out or falling out at the front and rear edges of the tread mat.
  • a stair mat comprised as above-mentioned of the present invention may be provided with a fluorescent strip on the upper surface of the front edge of the tread mat or the edge covering bead.
