The invention relates to a one-piece suspension device (20) for a divan base, comprising external suspension walls (34, 36), the device having a first and a second plane of symmetry (P1, P2). The invention is characterized in that the device additionally comprises at least one pair of internal elastic suspension walls (40, 42) which are symmetrical with respect to the first plane of symmetry (P1), each of the internal suspension walls (40, 42) having at least one curved mid-line extending in the second plane of symmetry (P2), each of the internal suspension walls (40, 42) being able to be folded along at least three separate fold lines (M1, M2, M3, N1, N2, N3) which are substantially orthogonal to the second plane of symmetry (P2). |
