A child's feeding seat includes a base (12), a tiltable seat for holding a child, and a removable feeding tray (18). The base has a bottom surface for supporting the seat upon a horizontal support. The tiltable seat includes a seat frame (14) with a back portion (42) and a pair of side arms (40), with the seat frame attached to the base in one of a series of selectable tilt positions, and a bottom portion (16) attached to the seat frame at one of a series of selectable positions for adjusting the height of the bottom portion with respect to the back portion of the seat frame. The feeding tray is adapted to be removably attached to both of the side arms of the seat frame. The base includes a pair of spaced apart slots (20) for receiving a strap to secure the seat base to the horizontal support, such as a dining chair.
