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.

Abstract: An article support and transfer assembly includes a carrier frame, which is selectively shiftable between raised and lowered positions relative to a countertop work surface, and an article support tray which is mounted for sliding movement in opposing directions between a first extended position, wherein the article support tray projects, at least partially, over the work surface and, a second extended position, wherein the tray projects over a side edge portion of the countertop. The tray can be shifted between the first and second extended positions for loading and unloading thereof and arranged in an intermediate position wherein the tray can be lowered with the carrier frame into a base associated with the countertop.

Abstract: A cooling or support rack is embedded into a work surface of a countertop at a position generally, directly in front of one or more doors of an oven arranged above the countertop. Preferably, the oven incorporates a pair of arcuate, sliding doors which are movable from a closed position to an open position wherein the doors do not extend over the cooling rack. The upper surface of the cooling rack is substantially flush with both the countertop and a lowermost cookware support surface within the oven such that cookware can be readily slid into and out of the oven.
