Britax One4Life Slim ClickTight All-In-One Car Seat

The One4Life Slim All-In-One Car Seat takes your child from birth to big kid with trusted Britax safety, ClickTight installation, and a slim SpaceSaver™ design. As a convertible and harness-2-booster seat in one, it grows with your child for 10 years. It starts rear-facing with an extended capacity of up to 50 lbs., so your child can ride rear-facing longer. When your child is ready, it easily converts to forward-facing toddler mode (up to 65 lbs) and high-back belt-positioning booster mode (up to 120 lbs). With a slim outside and spacious inside, the 17.5” seat is designed to fit 3 across* without compromising safety and comfort. ClickTight helps you install with confidence, every time. 

*Britax cannot guarantee 3-across fitment in all vehicles
