The Britax Grow With You ClickTight Plus Harness-2-Booster Seat grows with your child from toddler to pre-teen. Use it as a forward-facing car seat with its 5-point harness, then once they’re ready to use the seat belt, the 5-point harness tucks away, transitioning to a belt-positioning booster. 

With its patented ClickTight installation, you’ll know it’s properly installed in three easy steps. Two layers of side impact protection surround the head, neck, and torso. Plus, SafeCell Impact Technology creates a crumple zone that absorbs crash energy. Convenience, safety, and adaptability make it the perfect seat for your little one for years to come.

CPS Techs

What is a CPS tech?

A CPS tech is a Certified Passenger Safety Technician. Our Cubby Moms who have certified as CPS techs are specially trained on how to properly install car seats and booster seats, ensuring they know everything there is to know about keeping children safe in vehicles.
Through required continuing education courses and hours of personal research and team training, our CPS techs are able to remain up to date on the latest technical information regarding child safety.
Question mark icon

How does a CPS tech get certified?

In order to become certified, each prospective tech must attend The National Child Passenger Safety Certification Training Program. After intensive classroom instruction, they must pass a variety of written tests, demonstrate their knowledge through hands-on skills assessments, and perform safety checks at a check-up event before becoming certified. They learn the ins and outs of car seat installation possibilities, installing car seats in different vehicles, harnessing methods, and more. The car seat and safety industry is constantly changing, so our CPS techs here at The Baby Cubby are an invaluable resource for parents purchasing a new car seat, or for ones who simply want someone to double check that their current car seat is properly installed.
