Child's toilet training chair

A child's toilet training chair for use on a flat supporting surface which includes a seat supporting structure and a seat with a central opening, the seat having:

• a. a front section that is pivotally attached to a front portion of the supporting structure by opposing posts extending laterally from the side edges of the seat proximate its front edge, and
• b. a rear section that is provided with an engagement member that projects downwardly from the seating surface,
• the supporting structure of the chair including a back extending to a position proximate the base of the chair, the back having a plurality of vertically-spaced receiving elements for securely receiving the at least one engagement member of the seat, the topmost receiving element being positioned to align the seat in a substantially horizontal position for use and the lowermost receiving element positioned to engage the seat at a rearwardly declined acute angle for use, the supporting structure of the chair further including a pair of elongated openings formed in opposing vertically extending side walls, said pair of elongated openings dimensioned to receive the posts of the seat to thereby allow the seat to slide back and forth with respect to the back of the chair to thereby facilitate the movement of said seat to different receiving elements wherein the sliding movement of said posts is maintained within said elongated openings and without separation from said elongated openings, and
• a waste receiving receptacle that is removably secured in a position below the underside of the seat and surrounding the central opening in the seat, whereby the placement of the engagement member in the lowermost receiving element in the back of the chair positions the seat for use by a child in a low-squatting posture.
