Featuring ClickTight installation for quick, secure setup, extended rear-facing capacity for enhanced safety, and breathable SafeWash fabrics for easy cleaning and comfort, this seat combines premium protection with parent-friendly convenience. Its steel frame and SafeCell technology meet rigorous safety standards, making it a trusted choice for families seeking longevity, style, and peace of mind on every journey. ## Description 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 car 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, highback booster car 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.

Review: Fits 3 in Subaru Outback! - The look of this car seat is great. It’s got loads of padding, very sleek. Looks comfortable for my big toddler as well as my petite toddler. Needed to buy these to fit 3 across in my Subaru Outback. Easy to install, look durable. We’ve had them for more than 6 months and they hold up well. I feel that my kids are safe and well supported all while fulfilling the need to be slim in order to have 3 across by backseat. Right now we have 2 installed but already purchased the 3rd one for our newest baby. Would highly recommend. Review: Safety - I’ll give it 5 stars for safety but it’s very hard to get the baby buckled in because straps are short and can’t be lengthened or let out. My baby is 2 and as she grows I’ll probably have to buy another car seat because of the length of harness straps. ## Features - ONE CAR SEAT FOR LIFE: Designed to grow with your child for 10 years, this all in one car seat easily converts from a rear facing infant and toddler car seat (5-50 lbs) to a forward facing car seat with a harness (30-65 lbs) and, finally, to a highback booster (40-120 lbs). *Due to regulatory changes, weight and height ranges may vary by model; always follow the weight and height specifications listed in your product's user guide and on your product labels - FAST, SECURE, & PARENT-FRIENDLY INSTALLATION: With ClickTight technology, you can install with confidence in 3 easy steps: pinch to open, thread and buckle, click it closed; the accessible color-coded belt paths make it easy to route the seat belt through the correct path for each mode - EXTENDED REAR-FACING CAPACITY: Accommodates children up to 50 lbs and 49” rear-facing, so your child can ride rear-facing longer - TRUSTED BRITAX SAFETY: This 3 in 1 car seat is equipped with a steel frame, SafeCell technology, two layers of energy management, and our patented V-shaped tether; the seat is side-impact tested according to FMVSS 213a;* it is also tested to FMVSS 213 frontal impact standards.
