Britax Frontier CT Combination harness-to-booster

Quick Overview

The Britax Frontier CT Combination Harness-2-Booster boasts the ground-breaking CLICKTIGHT Installation System. 

Safety Features:

  • The 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
  • 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 was 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

* Required



  • NEW! 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.)


Check out ClickTight in action:


  • NEW! EZ-Buckle System keeps the harness buckle in a forward position and prevents the child from sitting on the buckle when they get in their seat
  • NEW! Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash.
  • NEW! Easy-Remove Cover allows easy cleaning without disassembling the harness or uninstalling the car seat
  • Tangle-Free, Five-Point Harness (with 9 harness height positions -up to 20.5”) distributes crash forces across the strongest parts of the body and provides a secure fit
  • Energy Absorbing Versa-Tether anchors the top of the car seat to the vehicle using a two-point attachment, minimizing the amount of forward movement of the car seat. Stage-released stitching helps reduce the crash forces reaching the child.
  • Harness Ultra Guard System (HUGS) provides resistance to forward movement in the event of a crash
  • Front-Adjust Recline for optimal child comfort
  • Two Buckle Positions offer a snug and secure fit for your growing child
  • Quick-Adjust No-Rethread Harness easily adjusts the harness shoulder height and head restraint from the front of the seat without disassembling the harness straps
  • Easy transition from Harness to Booster mode without removing harness straps
  • Integrated Cup Holders and Storage are designed for easy access to children’s cups, snacks and toys
  • Color-Coded Vehicle Belt Guides provide clear indication of the path and positioning of the vehicle seat belt for use in either harness or booster mode
  • In booster mode, compatible with SecureGuard clip which works with the vehicle safety belt to prevent the child from sliding under the lap-belt portion of the safety belt during impact, thus minimizing the risk of abdominal injury (clip sold separately)

Customer Reviews

Almost Perfect Combo Review by Nancy
We got two of these seats for our kids because we were constantly taking their seats in and out, and because we knew they'd be in boosters soon and didn't want to have to buy whole new seats at that point.

LOVE LOVE LOVE the click-tight feature to install them. Haven't had any problems getting the harnesses tight each time. Our oldest is now using hers as a booster and we got the seat belt guard from Fiddleheads that prevents her from sliding under the belt.

Overall, love Britax seats and love our Frontiers! (Posted on 2014-11-23)
Easy to get in and out Review by Ellen
My 3-year-old has been using this seat for a number of months now. I like that it is easy for her to climb into and out of by herself, and the seat is very sturdy. I do find it very difficult to tighten snugly; I have to shove my arm between the back of the seat and the car seat, and pull on the webbing from there in order to get the straps tight. We have yet to use it as a booster, so I cannot comment on that. (Posted on 2014-01-05)
