Abstract: A child car seat includes a seat frame having a vertical seat back portion and a horizontal seat bottom portion, both covered with a resilient padding material. Lateral supports on the seat back and seat bottom portions restrain a child from lateral movement, and a padded vertical leg divider extends upwardly on the seat bottom portion. A pair of mounting posts extend upwardly from opposite sides of the seat bottom portion, adjacent a forward edge and a tray is detachably mounted by a releasable hinge on each of the mounting posts. The tray may be selectively pivotally raised from either a left or right side of the seat bottom portion, or may be entirely detached and removed from the seat. A pair of fasteners are provided on opposite sides of the seat frame for engagement with opposite buckle ends of a conventional vehicle seat belt.
