Should you buy the Britax One4Life ClickTight All-in-One Convertible Car Seat?
The Britax One4Life ClickTight All-in-One Convertible Car Seat is the all-in-one car seat that covers infant rear-facing (5-50 lbs), forward-facing (22-65 lbs), and high-back booster (40-120 lbs) at $399. The ClickTight installation system eliminates the typical car seat installation mistakes (loose belts) by having parents fully thread the seat belt through and click the latch closed (rated #1 ease-of-install by IIHS), the rear-facing 5-50 lb range covers infants through 4+ year-olds in rear-facing mode (matching AAP safest recommendations), the patented SafeCell impact-absorbing base reduces crash forces, the V-shaped tether reduces rotation in collisions, the 14-position recline accommodates car geometry, the included 7 layers of side-impact protection wrap around the head, and the steel-frame construction supports 120-lb booster mode users. The trade is real money and a 30-lb weight that takes effort to move between cars.
