A positioning device for a car seat indicates when the car seat has been properly positioned in an automobile or on a shopping cart. The positioning device includes a paper backing which is encapsulated in a plastic housing. The plastic housing includes a relief projection in the shape of an arc. A ball slides within the relief projection and against the paper backing. Printed information on the paper backing indicates when the seat is in the proper orientation according to the position of the ball.
