Abstract: A potty chair having a seat member a central opening therethrough. A number of spaced legs are pivotally mounted on the seat member and move from extended position for supporting the seat member on a surface therebelow to collapsed positions along the bottom of the seat member. The seat member itself is formed of two parts which are hinged together and which fold into a compact form to fit in a small space or a carrying case. The legs are held in position along the bottom surface of the seat member when the two parts of the seat member are folded into their compact, side-by-side position. The seat member has spaced projections which extend toward the center of the opening and are adapted to extend into spaced holes near the upper, open top of a flexible, disposable bag, whereby the bag is aligned with and depends from the central opening to receive human wastes when a child sits on the seat member.
