Abstract
A bedding foundation comprises a pair of elongated rigid metal side rails, a pair of elongated rigid metal end rails, the side and end rails being fixed to each other and arranged to form a rectangle. A plurality of elongated rigid metal cross rails are fixed to and extend across the rectangle in spaced parallel relationship to one another. The side and end rails are joined together by insertion of an end of a respective side and end rail into respective channels of a corner joint having two open-ended channels formed therein at right angles to each other. The foundation rails comprise a top portion with a pair of side portions depending from the top portion defining a generally U-shaped channel with the top portion. Foundation covering is preferably attached to the foundation by tacking it to the metal rail or to a penetrable material carried within the side and end rail channels, or by using an elongated wedge to fix the covering within these channels.
