Improved sofa-bed, characterized, essentially, because the sofa support frame is constituted by a U-shaped vertical frame whose lateral and central sections conform rectangular frames of which the sides comprise inferiorly as studs to support the set, the aforementioned sides being joined together superiorly by a crosspiece parallel to the central frame, which crosspiece comprises several lower plates to which are associated respectively two tubular guides located in the same horizontal plane, one of which has arched shape and is joined by one end to a top vertex of the u-frame while the opposite end makes it to the vertical rail of the cross-piece, located approximately in the center thereof, while the other guide, which is rectilinear, departs from the cross-bar of the cross-member located in the center. Proximity to an extreme of it until converging to the extreme e a side of the frame, all arranged in such a way that the arrangement of the guides allows the rotation of 90s of the frame of a bed base located in a lower plane than the guides, for which purpose the aforementioned bed frame includes in the area of the head a vertical plates supports of U-shaped pieces provided with hook-shaped rods to slide through the mentioned guides and whose displacement is facilitated by lower bearings that includes the aforementioned frame of the bed base in the footwell area.
