Britax Frontier Clicktight Booster Car Seat

Calculated at Checkout

A perfect blend of safety, relaxing comfort, and superior convenience come together in the Britax Frontier. The Frontier is the best way to graduate from a convertible seat! A Harness-2-Booster seat allows your child to be fit perfectly and safe in their seat without the need to buy two separate car seats after their convertible seat. Harness straps are used just like any other 5-point harness seat, and then simply tuck away into the back of the seat when you transition to using the seatbelt. The Frontier is also equipped with all of the other amazing features Britax puts in their seats; SafeCell impact absorbing technologies, easy ClickTight installation, steel reinforced frame, and a long expiration date.
