The Britax One4Life All-In-One Car Seat is exactly as it sounds-one car seat to last your child through their car seat-using years. This convertible car seat grows with your child from 5-120 pounds until they no longer need a protective seat while riding in the car. This convenient convertible seat becomes three seats.
First, the chair is a rear-facing infant car seat. Use it to bring your new baby home from the hospital up until they are 50 pounds. Once your child outgrows the car seat, the chair transitions to a forward-facing 5-point harness seat. Finally, your older child can use the chair as a high-back belt-positioning booster seat until they are 120 pounds.
Drawback: No Backless Booster
This convertible seat does not `have an option for a backless booster seat. These features claim to give you ten years out of one seat, as the average child does not reach 120 pounds until they are around ten-years-old.
In order to fit a quickly growing child, the Britax One4Life has a 15-position, quick-adjust headrest, and harness, as well as a quick-push, 9-position recline. These features combined allow your child to be safe and comfortable, no matter their height or weight combination. Even though this Britax Car Seat has numerous features and contraptions, it is still designed with comfort in mind for your little one.
The seat has built-in cooling channels and ventilated mesh to improve airflow and keep your child cool and comfortable. Dishwasher-safe cup holders keep drinks and snacks within an arm’s reach, and a removable head pillow is an added comfort to the ride.
