Abstract: The table includes tubular legs and nodes or technical pieces having a bottom arm to be plugged into the tubular legs and lateral slots for the tongued and grooved coupling of pieces at the end of arms constituted in pairs and connected to each other, those of one pair to the ones of the other pair by means of an intermediate tensor rod so as to configure a horizontal structure associated to the legs. A board is screwed both to the nodes and to the intermediate frame, particularly to plates connecting each pair of arms to the intermediate tensor rod.
