Abstract: A bedsheet anchor system including a triangular flat base having a pair of legs, a curved hypotenus leg, a top surface area, and a bottom surface area. The bottom surface area of the triangular flat base has a strab knob. Each of a pair of triangular planar members has a bottom leg, a side leg, a curved leg, an interior area, a lower exterior area, and an upper exterior area. Each triangular planar member is disposed atop the legs of the triangular flat base, so that each planar member and the triangular flat base intersect at a ninety degree triherdral corner. Each planar member has an adjustable panel with adjustable serrated teeth. A plurality of hooks and notches disposed on each of the panels is attachable to a top bedsheet and a bottom bedsheet.
