Abstract: An adjustable safety seat for children for use in a motor vehicle. Height and width configuration of the seat can be easily changed to suit children of different sizes or a growing child.The child's safety seat comprises a pair of side pedestals and a seat bench. Raising of the bench relative to the pedestals for a small child concurrently narrows the width of the seat and lowering of the bench for a larger child concurrently widens the seat.The safety seat and a child contained therein are securely and safely positioned on a vehicle seat by means of the vehicle seat belts.
