The simplified mechanism sofa bed comprises: a fixed structure that bears multiple frames hinged together, an extraction mechanism for at least the first frame from a housing inside said fixed structure, a flip-back mechanism of at least a second and a third frame in relation to the first frame, and at least one synchronising mechanism between the extraction and flip-back mechanism movements. At least said flip-back mechanism presents all couplings on or under the surface of said bed. |
