AbstractA wire support member for a foundation unit. The support member is composed of a continuous, planar wire element, comprising parallel upper and lower attachment segments and a sinuous central segment extending between the upper and lower segments. The central segment is composed of a series of C-shaped curved portions. A series of the support members can be used in rows to form a foundation unit, and the members can be located perpendicular to one another at the corners of a foundation unit in order to form a corner support.
