ABSTRACT:
A convertible sofa-bed apparatus for use in a sofa or a bed configuration has hingedly interconnected and supported by frame members, and one or more pivotable arms or swing arms pivotally connected with frame members and with the seat cushion unit. The pivotable arms are rotatable between a back horizontal position wherein the apparatus is in its sofa configuration, and a frontward horizontal position wherein the apparatus is in its bed configuration. The pivotable arm or arms are preferably secured to a cross-bar rotatably mounted between end frame members to support the back cushion unit in either a vertical sofa configuration or a horizontal bed configuration, and the back support arms are preferably spring-biased to urge the arm toward such vertical position.
