Abstract: A stabilized mattress border is provided which eliminates undesirable leaning. The border defines a center compartment within which air, flotation, or spring mattress inserts may be positioned. It includes a pair of rows of pocketed coils and a flat wire positioned above and between the rows. The flat wire is attached to the upper convolutions of each of the coils and exerts an inward force upon the entire mattress border. Additional border wires are provided near the exterior corners of the mattress border as well as inside the innermost row of pocketed coils. The appropriate padding and upholstery define the compartment within which the border coils and wires are positioned.

Abstract: The present sofa bed includes a mattress supporting bed frame which is operable to longitudinally compress a portion of the mattress when the bed frame is moved to a folded and storage seat position. The bed frame or telescoping section which permits longitudinal expansion of the mattress when the bed frame is moved to an unfolded and extended bed position. A simple and lightweight bed frame operating and support linkage operates the telescoping bed section when moved between the stored and extended bed positions. The longitudinal compression of the mattress permits the mattress to be stored in a relatively narrow space and to be expanded to a full length bed dimension when moved to the unfolded and extended bed position.
