A support can provide information and display objects. The compartment of the support is hinged to switch between a flat folded condition and an unfolded and open functional condition to receive an object. It comprises a retractable wall (115) for holding the compartment in its unfolded and open condition and an elastic element (127) for biasing the holding wall in an unretracted holding position. The flattening of the compartment is done by retracting the holding wall against the action of an elastic element. The pivoting holding retracting wall (115) is a shoring wall between a floor face (105) and a ceiling face (103) with which they form a force descending rod.
