The Graco SlimFit 3-in-1 Car Seat grows with your child, from rear-facing harness (5-40 lb.) to forward-facing harness (22-65 lb.) to highback booster (40-100 lb). It saves space in your back seat, while giving your child plenty of room to grow. The unique, rotating cup holders simply rotate away, making the seat 10% slimmer to save precious back seat space. The Simply Safe Adjust Harness System means you can easily adjust the harness and headrest together, to accommodate your growing child with ease.
