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 car seat. This car seat and booster combo takes your child from birth to big kid with trusted Britax safety, ClickTight® technology for easy car seat installation, and parent-approved convenience features. One4Life starts in rear-facing mode with an extended capacity of up to 50 lbs, allowing your child to ride rear-facing longer. It easily converts to forward-facing toddler mode (30-65 lbs) and belt-positioning booster mode (40-120 lbs).* Thanks to ClickTight technology, you can install the seat with confidence, every time.

• ALL-IN-ONE CAR SEAT: Designed to grow with your child for 10 years, easily converting from a rear-facing infant and toddler seat (5-50 lbs) to a forward-facing seat with a harness (30-65 lbs) and, finally, to a high-back booster (40-120 lbs). *Due to regulatory changes, weight and height ranges may vary by model.
