Abstract: A portable baby seat has a flexible seat portion hung from a tubular frame for cantilevered mounting on a table edge. A U-shaped horizontal frame member extends through a hollow top seam of the seat's back and sides with end portions of the member extending forwardly for engagement with the top of the table. Each of a pair of lower support arms engage the underside of the table at a point forward of the U-shaped member's engagement. Each support arm is mounted by means of a rotatable sleeve on one of the U-shaped member's end portions. Connected to each sleeve is a curved member having a downwardly extending arm portion, a forwardly extending arm portion, and an upwardly extending end portion. The downwardly extending end portion extends in a direction away from the axis of rotation of the sleeve, while the upwardly extending end portion extends in a direction towards the axis of rotation of the sleeve.
