The child safety seat includes a seat body that is attached to a base that is held in place by the vehicle seat belt. The base provides for movement of the seat body around at least one axis. A turntable allows the seat body to be rotated from a safe-riding position to face the car door to facilitate positioning the child in the seat or to make it easier to grasp and maneuver a separable child carrier with the child in it. Inadvertent rotation of the turntable is prevented by a locking mechanism that remains engaged until released by the parent or caregiver. In one embodiment, a second axis of movement allows the seat body to be reclined so that the child's head is supported when he or she falls asleep. The reclining adjustment is a motorized motion which can be remotely controlled by the parent or caregiver sitting in the front of the vehicle via wires connected to a remote control.
