Why We Like It
The Britax One4Life is truly a birth-to-booster seat, eliminating the need to purchase multiple seats as your child grows. Britax's ClickTight belt-path system is the gold standard for seatbelt installation, and the SafeCell steel frame provides exceptional side-impact protection. At $500 it is a splurge, but the math works out if you skip buying separate infant and booster seats.
