## Description

Enjoy safe travels from birth to big kid with the Britax One4Life all-in-one car seat. This car seat features 4 configurations, including rear facing infant car seat, rear facing toddler car seat, forward facing 5 point harness car seat, and forward facing high back booster seat. Start with the rear facing car seat for infants and toddlers, then graduate to the forward facing car seat and booster car seat for preschoolers and big kids. ClickTight technology makes it easy to install your new baby car seat with confidence. Simply open the seat, follow the path to thread the seat belt, buckle it, and click the seat closed. The One4Life all in one car seat is outfitted with a high-strength steel frame, a SafeCell crumple zone, and a patented V-shaped tether. The protective seat shell and foam-lined headrest help absorb impact energy and are designed to help keep your child's head, neck, and body safe. Adjust the 15-position headrest and no-rethread harness at the same time, so you can find a secure fit in seconds. Quickly adjust between 9 recline positions and use the easy-read level indicators to find the correct angle. The Britax One4Life comes with an easy-to-remove, machine-washable cover, and the knit construction is naturally flame-retardant.

Review: Safe,carseat Doesn't wiggle when buckled installed. - All in one seat, love that when the seat is installed in car that it's not shifting/moving its locked in place many refacing seats seem to still wiggle which is terrible. Comfy my almost one year old sits great in it no issues seems to be a awesome carseat... down side it is kinda of heavy if needing to swap from one vehicle to next..not hard to installed though. Would buy again if I ever needed to*ended up buying a 2nd one to keep in 2nd vehicle *
Review: Yup, Buy it! - Very happy with this carseat! This is the 3rd one we've bought. We purchased and returned two as they felt cheaply made, unsafe and we didn't like the fit as well as how much they moved around after being tightly installed. This one is the exact opposite! It feels incredibly well made and safe, it doesn't budge from its position tightened down in the car, our 8 month old fits great in it and I'm happy with the amount of padding around the head. Great quality, great fit, durable, manufacturer takes the safety of your child seriously! Highly recommend!
