Your child is growing up fast, hitting new milestones every day. One moment you’re taking them to their first day of preschool, and before you know it, they’re ready for big-kid adventures. As they grow from adorable toddler to on-the-go kiddo, they’ll need a versatile car seat that’s designed to grow with them. The Grow With You™ ClickTight® harness-2-booster is designed to take your child from toddler to big kid, easily transitioning from a forward-facing car seat with a 5-point harness to a high-back booster. It all starts with ClickTight® technology, which makes it easy to install the seat in harness mode in just three simple steps: open, thread and buckle, click it closed. When your child is ready to ride in a booster, the harness stores away quickly and easily. In booster mode, Grow With You ClickTight can accommodate children up to 120 lbs and 63” tall, giving your big kid additional room to grow. This combination car seat is thoughtfully designed with features such as a washer and dryer-friendly cover, naturally flame-retardant fabrics, two cup and snack holders, and a 9-position, no-rethread harness. SafeCell® technology in the base acts as a crumple zone to help absorb crash energy, and the high-strength steel frame helps provide stability. Plus, the soft fabrics and premium padding help keep your child comfortable on every ride. With enhanced comfort for your child, parent-inspired convenience features, and trusted Britax safety, Grow With You ClickTight is designed for smooth rides and seamless transitions.
