ABSTRACT:
The high-chair has a base stand constituted by two mutually foldable arms. A chair-like body is slidably supported on one of the arms and has a back which is rigidly associated with guiding elements for sliding on the related arm. A seat is hinged to the back and is in turn hinged to a foot-rest which can be folded, together with the seat, toward the back. Elements are provided for releasably locking the chair body onto the related arm and allow a continuous sliding of the chair body on the arm for movement in the direction of lifting the chair body and, in discrete and successive portions, for movement in the direction of lowering the chair body.
