Abstract
A sleeper sofa includes an inner spring mattress which has hingedly connected head and foot sections. The hinge permits the mattress to be folded between a sleeping position in which the two sections extend horizontally and a sitting position in which the foot section is folded on top of the head section. The springs of the head section have less compressibility than the springs of the foot section so that the head section is relatively firm and the foot section is relatively soft. When the foot and head sections are in their sleeping positions, the relatively firm head section supports the torso of a person resting on the mattress and provides firm, comfortable sleeping support. When the foot section is folded to the sitting position, the relatively soft foot section provides good sitting comfort.
