A shelf is a flat horizontal plane which is used in a home, business, store, or elsewhere to hold items of value that are being displayed, stored, or offered for sale. It is raised off the ground and usually anchored/supported on its shorter length sides by brackets. It can also be held up by columns or pillars. A shelf is also known as a counter, ledge, mantel, or rack. In Spanish, a shelf is called estante.
