The Graco Atlas 65 2-in-1 harness booster car seat is designed to grow with your child from harness booster (22 – 65 lb/ 10-29.4kg) to highback booster seat (30 – 100 lb/ 13.6-45.3kg). The ultra-easy Simply Safe Adjust Harness System allows you to adjust the harness and headrest together to 10 height positions, with no rethreading. It features a handy harness storage compartment, which allows you to keep the harness with the seat, even when you’ve transitioned to highback booster mode. It also comes with dual cup holders and a machine washable seat pad, buckle cover and harness covers.
