• the furniture according to the invention comprises a base or lower support structure 1 comprising feet 2 for supporting the ground.
• the frame 1 may include, as is known, side armrests, which are however not shown in the figures.
• a bed base 3 comprising a seat frame 4 and a file frame 5 comprising a hinge 6 between them, directed in the lateral direction Y or 16 in FIG. 7.
• the articulation 6 between the frames 4 and 5 is of the type known under the click-clack and comprises a seat position, in which the frame 5 of the backrest is locked in a raised position relative to the frame 4 of the seat, making a obtuse angle determined rearward therewith, as shown in Figures 1, 2 and
• the transition from the seat position to the bed position takes place in the plane XZ transverse to the articulation 6, by first tilting the frames 4 and 5 back while keeping their obtuse angle , so that the back frame 5 is found horizontally on the base 1 and the seat frame 4 is in the raised position forward, as shown in Figure 3, then folding forward and down the seat frame 4 on the base 1 horizontally in the direction of the arrow indicated in Figure 3, to the bed position.
• the transition from the bed position to the seat position is carried out by performing these operations in the opposite direction in the plane XZ transverse to the joint 6.
• the seat and backrest frames 4 are arranged respectively a seat mattress 7 and a backrest mattress 8, the frames 4, 5 respectively comprising slats 14, 15 for supporting the mattresses for this purpose.
• the mattresses 7, 8 are arranged so that they can slide freely transversely on the frames 4, 5.
• the seat mattress 7 has a front end 9 remote from the back mattress 8 and from the articulation 6, the direction going from the 'front to back defining the direction in which a person leans against the backrest mattress 8 in the seat position.
• the seat mattress 7 has a first connection 12 with the back mattress 8 and a second connection 13 with the back frame 5.
• the first link 12 is located on the upper parts of the mattresses
• the mattresses 7 and 8 are of rectangular cross section in the transverse plane XZ and each have an upper face 17, 18 remote from a lower face 19, 20 facing respectively the seat frame 4, and towards the back frame 5.
• the mattresses 7, 8 and the piece of furniture are asymmetrical, the seat mattress 7 having a length L1, along its upper face 17, greater than the length L2 of the back mattress 8 along its upper face 18 and being said to be long relative to the mattress 8.

• the fastener 22 is for example formed by a band sewn onto the mattresses 7 and 8.
• the backrest mattress 8 is partially supported by its front face 21 on the seat mattress 7, which advantageously makes it possible to reduce the length L3 of the seat mattress 7 offered for support of a human being on its upper face 17 in the seat position.
• the preceding dimensions are determined so that this length L3 of the seat mattress 7 offered for support, which is that taken up to the back mattress 8, is less than or equal to the length L2 of the back mattress 8.
• the first link 12 directly connects the edge 26 of the seat mattress 7 to the edge 24 of the back mattress 8, connecting its upper face 18 and its front face 21, for example by a sewing edges 23 and 24, or others.
