The structure (1) has an upright (3) hinged at one end to a plate (2) about an articulation axis parallel to the plate between a folded position and an unfolded position of use orthogonal to the plate. A folding arm (4) connects the plate and the upright, and an opening mechanism locks the arm in an extended position. The plate includes a structural frame on which a circulation floor (7) is mounted, where the circulation floor is made of synthetic material. The circulation floor includes polyurethane foam mixed with a hardener. |
