Abstract
Abstract A colander is mounted within a stackable base adapted to rest on a surface and to support the colander above the surface. The base includes a top wall, which receives and retains the colander, and supporting legs with the colander disposed between them. These legs are shaped to permit a paired colander and base to be stacked within other paired colanders and bases.
