Car Seat Transition Checklist

A simple guide to knowing when your child is ready for the next car seat stage

From Infant Seat to Convertible Seat

Transition when any of the following are true:
☐Child reaches maximum weight limit (per your infant seat manual)
☐Child’s head is less than 1″ from the top of the seat shell or the head restraint when full extended
☐You’re looking for longer-term seating that stays installed in the car

Rear-Facing to Forward-Facing (Convertible Seat)

Stay rear-facing as long as possible. Transition when:
☐Child has outgrown their car seat in height OR weight limits, when installed in the rear-facing mode
☐Legs touching seat back? That’s ok! Height alone is not a reason to switch
☐Child’s head is less than 1″ from the top of the seat shell or the head restraint when fully extended

Forward-Facing (Convertible Seat) to Booster Mode

Stay in a five-point harness as long as possible. Transition when:
☐Child reaches maximum weight OR height limits for their car seat
☐Harness slots are below the shoulders when installed forward-facing
☐Can sit unassisted and stay upright for the whole ride
☐Is mature enough to keep seatbelt properly positioned
☐Ready for booster, not just physically, but behaviorally

Booster to Vehicle Seat Belt Only

Most kids need a booster until 10–12 years old!  Use the 5-Step Fit Test to see if your child is ready:
☐Back is flat against vehicle seat
☐Knees bend naturally at seat edge
☐Lap belt fits across upper thighs/lower hips, not stomach
☐Shoulder belt sits across chest and shoulder, not neck
☐Can stay seated properly for the entire ride

Pro Tip: Always refer to your car seat manual and vehicle manual as your primary guides!
Remember, the safest seating position is the one that works best for your car seat, vehicle, and family. When in doubt, reach out to our Customer Experience Team or schedule a Virtual Car Seat Check!
