Grow With YouTM
Harness-2-Booster Car Seat

 
 

The Grow With You™ harness-2-booster easily transitions from a forward-facing car seat with a 5-point harness to a high-back booster, growing with your child from toddler to big kid. Installing this toddler car seat is simple using the premium quick-push LUAS connectors. When it's time to make the switch, the harness stores away quickly and easily, converting the seat into a belt-positioning booster that accommodates children up to 54.4 kg (120 lbs) and 160 cm (63”) tall. This seat is thoughtfully designed with convenient features such as two cup holders and a 9-position, no-rethread harness. SafeCell® technology in the base acts as a crumple zone to help absorb crash energy, and the high-strength steel frame helps provide stability. ​

Now available! Fabric options free of flame-retardant chemicals & safe to machine wash & dry.
