Review: Britax Frontier XT Harness-2-Booster Seat

Britax has always been the car seat of choice in our family. The quality, workmanship and overall product really can’t be beat. With our eldest daughter nearing the big 4, I began researching various booster seats. She is quite tall for her age, and as the regular car seat just wasn’t cutting it, we needed something roomier. Because of her “adventurous” nature, my daughter needed something that would provide her with that additional bit of security,.

Britax recently introduced the updated Frontier 85 Harness-2-Booster Seat (for the US) and Frontier XT (designed for the Canadian requirements), and sent us this brilliant piece of kid gear to test out. The great thing about this combination seat is it the only one on the market that allows for the longest use of a 5 point harness. Children can be 2-years-old (25 lbs minimum) in order to begin using it,  and it keeps your child safe and secure in a traditional 5 point for up to 85 pounds (for the 85) and 65 pounds (for the XT). This seat also works as a belt-positioning, high back booster up to 120 lbs!

Out of the box, assembly was even more simple than a car seat and took me about 5 minutes from start to finish. As part of their update to the Frontier, Britax has redesigned the belt paths which make installation even easier than before! Since we started testing this seat a couple of months ago, my daughter has grown (yet again) and I’ve had to make a couple of adjustments. Because of the no-re-threading harness (tangle-free by the way), I was able to adjust the straps in seconds while she sat in her seat. The Quick-Adjust Head Restraint easily adjusts the harness shoulder height, without dissembling or removing the harness.

There are also 10 harness height positions (up to 20″) and three buckle positions. I would love to see the three buckle position feature, a regular for Britax car seats, because it really does make a difference with comfort – especially when your child is growing so rapidly!

The Frontier-XT is made for comfort travel! The integrated armrests are strategically placed, to provide a natural place for your child’s arms. The cup holders are generously sized and fit both small bottles of juice as well as our larger stainless steel canteens. Loved this! Because our daughters sit side-by-side, they were able to “share” this feature as there is a cup holder on either side.

Additional perks:

  • True Side Impact Protection distributes crash forces, shields from vehicle intrusion and contains the head and body while keeping the neck, spine and head aligned to limit injury.
  • Plush, Premium Cover Set (featuring thick comfort foam) in 5 sophisticated, simple patterns. Both gender-neutral as well as boy and girl colours are available.
  • Energy-Absorbing Versa-Tether®. This is actually a staged-release tether webbing. It slows the forward movement, thus reducing crash forces reaching the child and minimizing forward rotation.
  • Energy-Absorbing Base deforms in the event of a crash to absorb impact forces
  • Certified for Aircraft Travel in Harness Mode

One of the biggest pet peeves with car seats, is that children outgrown them in the blink of an eye. The Britax Frontier XT Harness-2-Booster Seat and Frontier 85 could easily be the only one you will ever buy again, as it will take your child from the age of two, straight to “car seat graduation”.

Check out the video below for more information and demonstrations of the Frontier 85 (US version).

Price:  $279.99, a list of retailers can be found through Britax USA or Britax Canada.

*Thank you to Britax for sending us this seat for testing. As with all of our reviews, the findings posted here are honest and true.*
