Sofa bed comprising innovating mechanisms for position adjustment and quick assembly. It comprises padding elements supported by two hinged frames and is characterised by a mechanism which allows the wheels of the front legs to touch the floor in both position said "bed" and "sofa. Moreover, said sofa bed comprises a mechanism which locks the rotation of the seat frame respect to the back frame and to obtain a lever which makes easier to convert the bed into a sofa.Finally, according to a subsequent aim, the assembly of a spacing bar to the right and left sides is less difficult; this spacing bar is needed to provide a sufficiently rigid base for the bed. |
