Abstract: A bi-directionally convertible infant car-seat/stroller in which the conversion is effected by operating a single pushbutton which is mechanically coupled to a pair of pawls on opposite sides of the car-seat/stroller, such pawls engaging respective detents in discs or drums rotatably supported from the frame of the apparatus on opposite sides of the apparatus until withdrawn against the force of respective return-spring by the operator's actuation of a single control button which is mechanically coupled by means of flexible cables or rods to such pawls and causes such withdrawal when desired, the result of such withdrawal being the enabling of the movement of the front and rear wheel assemblies of the car-seat/stroller from an extended to a folded position and vice versa as result of the coupling of pivot arms carrying the front and rear wheel assemblies being rotatable with the disc when the pawl associated with each disc is withdrawn from the detent in the disc, as a result of which the apparatus can be con
