The Britax One4Life convertible-to-booster car seat grows with your child for 10 years—from 5-120 lbs and up to 63” tall.  It converts from a rear-facing infant car seat, to a forward-facing 5-point harness seat, to a high-back belt-positioning booster seat.

As the only all-in-one car seat with ClickTight installation, it’s easy to install in seconds, so you’ll know it’s installed correctly every time. A high-strength steel frame, crumple zone, and V-shaped tether help absorb crash energy and two layers of side impact protection surround your child’s head, neck and torso so you can travel in total confidence knowing your child is surrounded with Trusted Britax Safety and Full Body Protection.

As your baby grows, adjust the 15-position headrest and harness in seconds to create the perfect fit. When it’s time for booster mode, simply tuck away the harness straps and buckle. With cooling channels, premium padding and built-in arm rests, your child will love the ride!


  • New and improved seat cover, easier to remove and install, as well as a tighter fit
  • Simplified harness storage
  • The harness simply tucks away behind the cover and under the seat pan, where previously it tucked away in the storage compartment of the shell
  • LATCH hooks reduce confusion on installation method
  • ClickTight Installation System makes car seat installation as simple as buckling a seat belt
  • SafeCell Impact Absorbing Base compresses to absorb crash energy and counteract forward movement
  • SafeCell Impact Stabilizing Steel Frame gives you peace of mind knowing there is strength through the spine of the car seat where you want it most
  • SafeCell Impact Absorbing Tether minimizes potential seat rotation with our unique two-strap design and slows forward movement with our patented rows of stitching that “give-way” one at a time.
  • SafeCell Impact Absorbing Harness keeps your child’s chest clip correctly positioned and absorbs energy in the event of a crash.
  • Quick-Adjust, 15-Position Harness and 2-Position Buckle
  • 7-Position Recline with Automatic Level Indicator adjusts for your child’s comfort while ensuring the best installation angle for your vehicle.
  • Plush Foam Padding in the cover, buckle pad, shoulder pads and removable pillow surrounds your child in comfort at every touch point.
  • EZ-Buckle System keeps buckles and straps out of your way when placing your child in the car seat.
  • Easy-Remove Cover for cleaning convenience
  • Flip Forward Buckle Pad stays out of the way for easy boarding; made with extra padding for premium comfort
  • Built-In Cooling Channels and Ventilated Mesh improve air flow to keep your child comfortable

CPS Techs

What is a CPS tech?

A CPS tech is a Certified Passenger Safety Technician. Our Cubby Moms who have certified as CPS techs are specially trained on how to properly install car seats and booster seats, ensuring they know everything there is to know about keeping children safe in vehicles.
Through required continuing education courses and hours of personal research and team training, our CPS techs are able to remain up to date on the latest technical information regarding child safety.
Question mark icon

How does a CPS tech get certified?

In order to become certified, each prospective tech must attend The National Child Passenger Safety Certification Training Program. After intensive classroom instruction, they must pass a variety of written tests, demonstrate their knowledge through hands-on skills assessments, and perform safety checks at a check-up event before becoming certified. They learn the ins and outs of car seat installation possibilities, installing car seats in different vehicles, harnessing methods, and more. The car seat and safety industry is constantly changing, so our CPS techs here at The Baby Cubby are an invaluable resource for parents purchasing a new car seat, or for ones who simply want someone to double check that their current car seat is properly installed.

Buy this seat!

This is my second time buying a britax one4Life from the baby cubby! My son is still using his at 4 so we knew my 1 year old needed the same one. This seat checks off all the things on my list for a great price.



Thank you so much for your review! We are so happy that you have found such a great car seat for your kids!

Peace of Mind

Jaycee was so kind and so knowledgeable when helping me pick out a new car seat for my baby. I asked millions of questions and she never made me feel like they were dumb questions. I now feel comfortable driving around in crazy Utah. Thank you Jaycee and Baby Cubby!



Jaycee is the best! Thank you for shopping with us!
