The invention relates to a movable support (40) for an entertainment and/or information device (50). The movable support is designed to be applied to the underside (310) of a substantially horizontal support surface (31). The movable support comprises: - a set of linear guides (41) designed to allow the device to be displaced in a substantially horizontal plane n, at least from a rest configuration (R) into a first transition configuration (Tl) and - a set of hinges (42) designed to allow the device to rotate about a substantially horizontal axis of rotation (X) at least from a first transition configuration (T1) into a first operating configuration (U1).
