A stair nosing is constituted by an edge base made of a hard material and adapted to be installed on the tread of a stair step, and an edge bead cushion formed on a surface of the edge base so as to be located at the stair tread nosing of the stair step. A positioning groove is formed on the surface of the edge base behind the edge bead cushion, and a gripper is adapted to be set in the positioning groove and to be secured to the edge base. The edge base is provided with a riser cover integrally formed at the front edge thereof so as to be positioned on the riser of the step in a manner to fit over the stair tread nosing. The gripper is composed of a sheet member adapted to be positioned in the groove and a number of spaced nails projected from the surface of the sheet member.
