ABSTRACT:
A bed frame comprising T shaped side rails provide support for a box spring and mattress. A leg assembly is affixed to the bed frame and is affixed to the side rail and to the cross rails for better strength of connection. The use of T-shaped side rails provides more resistance to twisting and bowing and thereby more resistant to damage a leg or other structural component of the bed frame from moving the bed frame across the floor. The use of the T-shape cross section side rails enables the overall bed frame to support more weight with less deflection than the convention L-shaped side rails. There are also headboard and footboard brackets that take advantage of the greater height of the vertical flange of the side rail to have affixation means, such as rivets, that are further spaced apart to provide a more rigid connection between the brackets and the side rails.
