An improved pocketed bed sheet is provided that avoids inadvertent placement of objects in a pocket, better controls placement and removal of objects from within its pocket, and deters babies and toddlers from accessing such pocket, all without the need for engagement or disengagement of a fastening member. The improved pocketed bed sheet includes a fabric body configured to substantially cover a mattress and a pocket provided on the fabric body. The pocket includes a wall configured to hold objects in the pocket and a diagonal fabric edge that defines a diagonal opening for predetermined angular ingress and egress into the pocket for controlling the placement and removal of objects within the pocket. The diagonal fabric edge is disposed at an angle relative to an edge of the fabric body.
