The frame assembly itself is comprised of (1) a pair of anchor members secured to the baby chair and dimensioned to overlie the tabletop, (2) a pair of vertical arm members extending from the anchor members to a seat portion of the chair and (3) a pair of grip members with gripper feet on one extremity to contact the underside of the tabletop and pivotably attached to the vertical arm members for movement. A latch means is associated with the anchor members and grip members to secure the baby chair to any thickness tabletop, yet allow ready disengagement therefrom.
