Abstract: A mattress cover/fitted bed sheet which consists of a substantially rectangular blank of textile material with opposed sides and opposed ends. A pair of generally triangular pieces are cut out of the opposed sides adjacent the ends. Each of the triangular cut outs has a pair of opposed sides, an apex directed inwardly on the textile material and a base coincident with one of the sides of the textile material. The sides of the triangular cut outs are joined to form a biased side seam such that, when placed on a mattress, textile material is drawn under the end of the mattress.
