The seat (1) is provided with a support frame (2) for an upholstered covering (3) arranged to define a seat portion (5) and a back portion (4), and comprising two facing lateral longitudinal members (19) rigidly joined by three cross-members. Each longitudinal member (19) is composed of a first plate (23) disposed vertically and carrying at its upper end (25) a second plate (24) to which a third plate (27) is connected parallel to the preceding. The cross-members are defined by a first U tube (22) shaped anatomically in such a manner as to define the profile of the back portion and rigidly joining together the upper ends (47) of the third plates (27) of said longitudinal members (19), a second U tube (20) shaped anatomically in such a manner as to define the front profile of the seat portion (5) and rigidly joining together the front ends (32) of the first plates (23), and a straight tube (21) which rigidly joins together the upper ends (25) of the first plates (23).
