It all starts with the first ride home. Then, there’s the first family outing. The first ride to daycare. Soon, you’ll be driving them to their first play date or soccer game. Throughout every change and milestone, you can count on one constant for your journey: the Britax® One4Life® all in one convertible car seat. This 3 in 1 car seat and booster seat combo takes your child from birth to big kid with trusted Britax safety, ClickTight® technology for easy installation, and parent-approved convenience features. One4Life starts as a rear facing car seat with an extended capacity of up to 50 lbs, allowing your child to ride rear facing longer. It easily converts to a forward facing car seat (30-65 lbs) and a belt-positioning booster seat (40-120 lbs)* when your child is ready. Thanks to ClickTight technology, you can install with confidence, every time. As your child grows, you can easily adjust the 15-position harness with just one hand — no rethreading required. This all in one car seat features a high-strength steel frame, SafeCell® technology, and a V-shaped tether, helping to give you peace of mind for the road ahead. The washer and dryer-friendly car seat cover is available in warm, neutral tones with a sophisticated aesthetic to match your lifestyle. Plus, it’s naturally flame-retardant with no added FR chemicals. The breathable knit fabrics allow airflow to help keep your precious cargo cool and comfortable**, while the plush padding helps make rides enjoyable. With thoughtful convenience features, premium comfort, and an all in one design, you can confidently navigate every stage of the journey with just one car seat — for life. *Due to regulatory changes, weight and height ranges may vary by model.
