The trailer consists of a chassis (1) on wheels (2) with a central horizontal platform (3) equipped with vertical supports (8,9) for two additional pivoted platforms (15,16) which can be deployed on either side of the central one. When the outer platforms are folded the trailer conforms to statutory dimensions, and when they are deployed they can support rows of seats (17,18,19) in a series of tiers. The platforms can be deployed and folded by a system which can be operated manually. The central platform has at least two telescopic masts (4,4') at its ends, supporting a cover (5) with hinged panels (6,6'). The side platforms are deployed and folded by a pulley and cable system (25,26), the pulleys (27, 27') of which are mounted on the telescopic masts.
