Graco’s Nautilus Elite harnessed booster goes the distance, from toddler to child, to help keep your growing child safe. It secures your child in a 5-point harness from 9-18kg, and then converts to a belt-positioning booster 15-36kg. The no-rethread harness allows you to adjust the harness and headrest together as your child grows, with no time-consuming rethreading. You’ll appreciate the strength of the steel reinforced frame, 3-position recline for your child's comfort whilst your little passenger enjoys a cup holder and storage compartment. It's the last car seat you'll ever need!
