This favorite has been going strong for us for over 3 years. The Britax One4Life car seat grows with your kid from infancy to the booster years. This investment piece has top ratings for safety and is easy to install. This is the only car seat you’ll need and our preference over an additional base for an infant car seat carrier. Our kids are the most comfortable in their Britax versus other leading competitors. Currently on sale, a rarity, for 20% off!
