Abstract: A cutting board and countertop are correspondingly constructed to enable the cutting board to be supported upon the countertop in multiple, varying height positions. The countertop preferably includes a main, substantially planar work surface provided with a frontal, upstanding lip, as well as at least one ledge provided at a position spaced across the work surface from the lip. The cutting board is generally constituted by substantially planar member having support elements provided on opposing, terminal side portions. In a first height position, the cutting board is arranged against both the lip and the ledge. In the second height position, the cutting board is inverted and positioned against the frontal lip and upon the ledge. In either position, the cutting board can readily slide along the countertop.
