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.
