Abstract: A tapering-depth shelving unit is disclosed. The tapering-depth shelving unit is particularly suitable for use in the space behind a door. The shelving unit has two generally vertically extending support members spaced horizontally from one another, with a plurality of shelves mounted generally horizontally between them. The first support member has a depth less than the depth of the second support member, and each of the shelves matches the depth of the first support member on one side edge and matches the greater depth of the second support member along the other side edge. Each of the shelves increases gradually in depth between the first support member and the second support member. The shelves have a generally trapezoidal shape in plan view.
