A juvenile vehicle seat includes a seat, a support base under the seat, a first belt retainer coupled to one side of the support base, and a second seat belt retainer coupled to another side of the support base. To retain the juvenile vehicle seat in place on a first side of a seat in a vehicle, a vehicle shoulder strap associated with that first side of the seat is moved to engage one lower portion of the support base and pass through a channel provided by the first belt retainer so that it extends diagonally behind the juvenile vehicle seat (from left to right) in an "upwardly" sloping direction. Alternatively, to retain the juvenile vehicle seat in place on the other side of a seat in a vehicle, the vehicle shoulder strap associated with that side of the seat is moved to engage another lower portion of the support base and pass through a channel provided by the second belt retainer so that it extends diagonally behind the juvenile vehicle seat (form left to right) in a "downwardly" sloping direction.
