Improved bed frame for a sofa bed, which being of those that externally adopt the shape of a conventional bed frame, is essentially characterized by being constituted by a rectangular frame, which is formed by a tube with circular bracket section that joins two angular profiles by means of two pieces interspersed at the ends of the tube with connecting pins, the ends of the angular profile being connected to a second frame constituting a point of support, through two elbow pieces, a second support element consisting of a plate having been provided. An obtuse angle in its path joined to the bracket tube by means of a pin, having placed on both sides of the rectangular framework of the bed base a flat bar also joined by pins. The frame of the bed frame at one end and on the other joins another elbow plate which in turn is joined by a pin in the middle part of what constitutes the support element.
