Britax Frontier CT booster seat.

ClickTight Installation System


allows parents to easily achieve a safe and secure installation using the vehicle seat belt throughout the life of the seat, in harness mode, without having to worry about the weight of their child (May not be compatible with all vehicles. See installation instructions.)

True Side Impact Protection


provides deep side walls and a head restraint with energy-absorbing EPP foam to distribute crash forces, shield from vehicle intrusion, and contain the head, neck and body while keeping them “in true” or aligned

Base with SafeCell Technology


designed to keep your child safe and secure in a crash by compressing and significantly lowering the center of gravity, reducing the forward movement of the car seat

  • Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash

Best combination seat money can buy
I bought a Frontier a few years ago for my daughter who used it from the time she was ff at 3 until about age 7 with the 5 point harness, and still uses it now at 9 as a booster.

The Frontier is by far the best seat we have used, and will be purchasing a new one for baby #2.

Excellent and Easy to install
Love this car seat, I bought it on sale and am so pleased with it. It was the perfect addition to my need to transition to a harnessed booster at 3 years old. I previously had the Britax BSafe and Marathon G4 so I knew the quality however this was the first purchase of a click tight seat and if you can pay the extra money it is worth it....I had thought it wasn't a big deal which is why the Marathon was not a CT but now I can only say how amazing it is. We have since purchased a Pinnacle CT as well for our main seat.

So easy to install!!! Kid loves it too.
Got the seat for my son who is 41lbs 38" & 2 1/2 yes old. He loves the arm rests and cup holders. We have it reclined and he is able to sleep in it fine.
Installing it was amazing!! Simple, speedy and secure.
The tether strap took the most amount of time. I could easily give this to my in-laws to install in their vehicle and be confident that my child will be safe with them.

the harness took some time to get adjusted to the right fit and to be familiar with it. It is a bit hard to pull on the strap and tighten it but after having it for a few trips we are happy with its performance.

it is so easy to adjust the straps so you don't have to uninstall mercy you just pull the lever and the height adjust automatically. and when it's time to put the seat in booster mode it's very easy to move the harness straps out of the way. I'm so pleased we purchased this car seat and highly recommend it to anyone!

Easy to install, heavy.
Purchased this for my four year old who is 42 inches tall and about 40 pounds. I wanted to keep him in a harness booster for as long as I could.

Its Britax, so great quality. Its quite heavy but very easy to install. Husband and I couldn't believe we installed it in one try and it didn't budge when pushed side to side (installed with click tight and belt).

Love it, our son loves the arm rests and cup holders.
