Abstract: An apparatus for holding a bed sheet, either flat or fitted, in place includes a flexible, non-elastic pad and attached strap. A clip on the end of the strap engages the corner or side of the bed sheet, and the flexible pad is slid beneath the mattress to hold the sheet in place. When force is exerted onto the pad due to pulling of the pad resulting from sheet movement, the flexible pad folds upon itself, thereby providing resistance to prevent the pad from being pulled from beneath the mattress. As the force on the pad increases the degree of folding increases, such that the pad self-adjusts to provide the necessary degree of resistance to hold the sheet in place.
