Grow With You™ harness-2-booster grows with your child from toddler to big kid. It’s made with premium fabrics and padding for superior comfort and style.

2 layers of side impact protection surrounds the head, neck & torso. SafeCell Technology in the base creates a crumple zone that absorbs crash energy. Installing the seat is simple using the premium, quick-push LATCH connectors or seat belt.

With arm rests, cup holders, and harness comfort pads, even big kids enjoy the ride.

Harness mode 11 - 29.5 kg; Booster mode 18 - 54 kg


V-shaped tether with staged-release stitches helps slow and reduce forward movement during a crash.


9-position, quick-adjust harness & headrest move together using one hand for the proper fit as your child grows.

4 cup and snack holders keep drinks, snacks, and toys within reach.

Color-coded belt guides make it easy for you and your child to route the seat belt through the right paths.

Easy-to-remove cover for cleaning without uninstalling the car seat or removing the harness.

Harness comfort pads keep your child’s neck from rubbing against the harness strap.

2 recline positions help you find the most comfortable fit for your child and the best fit for your vehicle.

V-shaped tether with staged-release stitches helps slow and reduce forward movement during a crash.

Industrial strength steel frame reinforces the seat structure to help keep it stabilized.
