Abstract
A child's seat includes a base structure having a central helical screw. A seat is mounted on a shaft for upward movement without rotation. Thereafter, the seat can only fall while rotating due to engagement of teeth respectively on a nut and on the shaft. After reaching its lowermost position, the nut is disengaged from the shaft to permit free rotation of the seat in either direction.
