The Britax car seat bundle includes the One4Life all-in-one convertible car seat and the Poplar S slim convertible car seat. The One4Life transitions through 4 configurations from a rear-facing infant seat up to a forward-facing booster for children 5-120 lbs and up to 63 inches. Its ClickTight installation system, steel frame, SafeCell technology and premium quilted padding provide safety and comfort. The Poplar S is a slim 17-inch 2-in-1 rear and forward-facing seat for children up to 65 lbs with similar safety features like ClickTight and SafeCell. Together these seats cover children from birth through the booster seat years. The One4Life maximizes longevity with 10 years of use as a rear-facing seat before transitioning to forward-facing. Its 4 configurations remove the need to purchase multiple seats as children grow. The slim design of the Poplar S maximizes fit and flexibility when used alongside other seats. Both models include dishwasher-safe cup holders, machine-washable fabric and premium comfort features. With trusted Britax safety and innovative convenience features, this bundle offers a comprehensive, long-lasting car seat solution for growing families.
