摘要： This pull-out sofa bed comprises a metal bed provided with a head section that can be raised to T.V. position, and releasably locked in such position, or released from such position and lowered to sleeping position, or folded over an adjacent long intermediate section of the bed to underlie the foot section of the bed folded thereover and also over said intermediate section, for compactness when shipping the bed. This bed has rear legs foldable underneath the intermediate section when the bed is fully collapsed, and also has means contacting the underside of the collapsed rear legs, to support the folded bed in a plurality of selected vertical levels of the sofa seat when the pull-out bed is collapsed and used as a sofa. The bed has means for locking the foot section of the bed to the intermediate section, in the folded or collapsed condition of the bed, to compress the mattress, which means is highly simplified and easy to manufacture. Further, the bed includes front legs, and means which could be separately shipped and which could be attached to the front legs by the upholsterer of the bed, to increase the stability of the bed in sleeping position.
