Designed to help make car seat setup quick, easy, and secure, the StayTight™ base takes care of the hard part of installation with a built-in seat belt tensioner and automatic lock-off. Simply lift the lever, route the seat belt through the accessible color-coded belt path, and buckle. Then, lower the lever to lock in place. Thanks to the DuoConnect™ system, you can effortlessly transition from car rides to strolls and back again. The base stays in your vehicle while the car seat easily clicks into the base and stroller (car seat and stroller sold separately). The easy-adjust recline helps you find the right angle for your vehicle, and the high-strength steel on the inside of the base helps provide stability. The StayTight™ base is compatible with the Britax® Arbor™ infant car seat (part of the Phases™ travel system, sold separately).
