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. It easily converts to forward-facing toddler mode (up to 65 lbs.) and high-back belt-positioning booster mode (up to 120 lbs.) when your child is ready. 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. The base and shell are easy to wipe down for hassle-free cleanup. The car seat cover is safe to machine wash and dry, and it’s naturally flame-retardant with no added FR chemicals. One4Life Slim features a high-strength steel frame, a SafeCell® crumple zone, and a V-shaped tether. As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand. With cooling channels, premium padding, three infant inserts, and built-in armrests, your child will love every ride. *Britax cannot guarantee 3-across fitment in all vehicles.

Britax One4Life Slim All-in-One Car Seat

The Britax One4Life Slim All-in-One Car Seat is designed to grow with your child from birth through the booster years. It starts rear-facing from 5–50 lbs, converts to a forward-facing harness seat from 22–65 lbs, and later becomes a high-back belt-positioning booster for children from 40–120 lbs.

With a slim 17.5" exterior, the One4Life Slim helps preserve valuable back-seat space while still providing a roomy interior for your child. Britax ClickTight® installation, a high-strength steel frame, SafeCell® technology and a V-shaped tether are designed to support secure everyday use through multiple stages.

One Car Seat From Birth to Big Kid

The One4Life Slim combines three stages in one seat, reducing the need to replace your child's car seat as they grow. Its extended rear-facing capacity allows children to remain rear-facing up to 50 lbs before transitioning into forward-facing harness mode.

When your child is ready, the seat converts again into a high-back belt-positioning booster with a maximum weight capacity of 120 lbs. The product has a useful life of 10 years.
