A device to secure the top sheet of bedding from being accidently pulsed out at the foot of the bed is disclosed wherein an elongated piece of plastic material is provided for placement between the mattress and the box springs of a bed wherein the end of the tucked-in top sheet of the bed is in contact with one side of the elongated piece of material, and the other side of the elongated piece is in contact with the box springs. The top sheet securing device is constructed of materials which have a high coefficient of static friction such that the weight of the mattress pressing down upon the tucked-in top sheet is sufficient to provide compression of the plastic material between the top sheet and lower box springs that the top sheet is held in position against the unintentional or accidental pulling out. the top sheet securing device may be alternately made of a thin sheet of vinyl plastic or a thickness of open or closed cell low density polyurethane foam, or a combination of vinyl plastic and polyurethane foam.
