What Stands Out
Automatic Tensioning
Equipped with an automatic seat belt tensioner, this base ensures a secure and stable installation every time, minimizing the risk of incorrect fittings.
Lock-Off DuoConnect
The Lock-Off DuoConnect system provides added security for the car seat, preventing seat belt slippage and ensuring ultimate safety for your infant.
Extra Convenience
Designed specifically for the Arbor Infant Car Seat and Phases Travel System, this extra base allows for easy transitions between vehicles, making it ideal for families on the go.
