The Britax Grow With You ClickTight Harness-2-Booster Seat seat grows with your child from toddler to big kid. Feel confident with your child's comfort and safety with its patented ClickTight installation. 

Safe to machine wash and dry, the removable car seat cover stays looking like new, mile after mile. That means quick, easy cleanup so you can keep moving. The fabrics are naturally flame-retardant, which means there’s no need for added FR chemicals.

Quickly adjust the 9-position harness and headrest using just one hand for the proper fit as your child grows. Once they’re ready to use the seat belt, the 5-point harness tucks away, transitioning to a belt-positioning booster. Color-coded guides help you route the seat belt through the right paths, and you can choose from plenty of fun colors to match your child’s unique personality.

With the Grow With You ClickTight Harness-2-Booster seat, your child will be proud of their "big kid" status!

    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.

    Love the seat

    I love this seat! Very clear directions in the manual, and overall easy to install. Unfortunately the seatback in my car slopes down toward the door, so the V tether on the back does not work and slips down one side. No big deal in my car, I just moved the seat into the 3rd row, but keep in mind the shape of your cars seats when looking at car seats. Easy to get the toddler in and out of, even being so far back. Still giving a 5 star review because the seat is awesome, you will not be disappointed if you purchase this.

    The Best!

    I love this seat. We outgrew our boulevard... not officially... but the way my little’s legs were hanging off the front made them hit the back of my seat all of the time. This car seat provides a much better angle for longer legs. Easy to install. I feel safe with my 4 year old in a 5-point harness... and I love that this set up will keep him in it and keep him safe for years to come.



    We are so glad you love this seat! Thanks for sharing your experience with us!
