Abstract: A chair and desk board assembly for a baby walker is provided in which the desk board has a front tray and a rear frame defining a chair hole. Horizontal holes are provided in a rear periphery of the tray and vertical holes are provided in the top surface of the rear frame. The chain has a substantially U-shaped member and an inner seat both made from a foam-like material, and studs are provided on a front surface of the chair for engagement with the horizontal holes. A mounting member having a curved wall conforming to the contour of the U-shaped member of the chair is provided and fits into the U-shaped member. Resilient tongues extend downward from the mounting member to engage the vertical holes of the desk board.
