A foldable stool formed with a platform of two panel members hinged together, with a plurality of telescopic legs hinged to the underside of the panels, the underside of said panels each fitted with spacer blocks along the outer edges of the panels for concealing the folded legs when the panels are folded together, with each telescopic leg formed of an inner member slidably mounted in a hollow outer member, said outer member formed with a through longitudinal slot extending for a portion of the length of said member in which slot rides the head of a key that is pivotally fixed to the said inner member, said slot formed with an enlarged section of a size to accommodate the head of the key in a first position of rotation of said key, with the remainder of the slot of lesser width so as to block movement of the key in said first position, and in the enlarged section of the slot, from travelling in said remainder of the slot, so as to latch the attached inner and outer members together when the key head is rotated to said first position in said enlarged section of the slot, said key mounted in said inner section so as to project into the enlarged section of the slot of the outer section in the extended position of the legs.
