Stool, characterized in that it is constituted by a metallic structure, in a tube or rod, closed on itself, that composes a rigid support formed by a plurality of pairs of vertical feet arranged circumferentially, each pair being connected by a lower section at ground level, and so that each pair extends coplanarly in the upper part, towards the central zone, forming a flat support for a seat, where each section of the same pair joins with the immediate section of the adjacent pair, having on the previous support a seat containing a rigid circular base that engages in the upper sections of the supporting structure, by means of grooved studs that are applied at elastic pressure, so that said seat has a diametral magnitude lower than that of the supporting structure object of allowing the stacking of several stools by mutual insertion until their seats are superimposed, with intercalation of the respective feet within the said circumferential arrangement.
