A floor covering suitable as an entrance mat comprises a plurality of tread strips of substantially resilient and flexible material, each tread strip having a wear layer of fibrous or fibrous like material whereby said tread strips provide a fibrous tread surface, and a plurality of spacer strips of substantially rigid material arranged interposed between the tread strips whereby each successive pair of tread strips is spaced apart by at least two of said spacer strips, and the pluralities of strips being secured together in side by side relationship by connecting means which pass through aligned apertures in the strips, each spacer strip comprising a pair of longitudinally extending and co-planar abutment faces to bear against and provide lateral support to a side face of a tread strip, the maximum spacing of extreme edges of said abutment faces as viewed in cross-section being less than the height of the side face of the tread strip whereby said pairs of spacer strips provide a recess region between a successive pair of tread strips.
