She said that her 4 year old daughter, who was strapped into the Frontier 85, walked away from the accident without a scratch. The mother also had a 22 month old son in an Evenflo Triumph car seat and he too, thankfully, was not hurt but one of the straps attaching the Evenflo to the car’s anchor ripped off. Luckily the seat did not go bouncing around but the Frontier 85 performed marvelously. She said she will be buying another Frontier 85 immediately.

Chief customer complaints about the Britax Frontier 85 Combination Booster Car Seat:

The seat has a net like material on the seat part (on the Rushmore color, not the Onyx, Maui Blue, Cowmooflage or Livia) that could get caught on clothing and tear. Has one pull strap for both latches, making it more difficult to install, as opposed to the Britax Marathon which has two independent straps. Several customers mentioned they would like the seat to tighten on both sides. One customer found the seat to be difficult to put back together without instructions after disassembling it for cleaning. Several customers that had complaints mainly had issues relating to installation in their particular vehicle. Most were small, subcompact cars. Several customers complained about the straps twisting.


We found a considerable amount of customers stating that this is their second or subsequent Britax car seat and that they have bought Britax seats more than once because of the superb quality, safety and craftsmanship of Britax car seats. This speaks volumes for these seats, as return customers mean that you’re doing something right. In particular, the Frontier 85 is one of the most highly rated seats we reviewed and the praises from satisfied customers is truly impressive. We could not find any reviews that questioned the safety of the Frontier 85. And with safety being the number one reason for buying a child car seat, the Frontier 85 should be on everyone’s short list when comparing seats. Comfort, ease of installation, and convenience features also ensure that the Britax Frontier 85 makes it to the top of the list for best all around performers. We would caution anyone buying the seat in Rushmore color to note that the seat, in this color, has a netlike material which can get ripped when caught on clothing or buckles. An alternative would be to buy the seat in one of the other colors which do not have the netlike material. We also found that several reviewers complained about the fact that the Frontier 85 tightens to the vehicle on one side and they would prefer it if the seat tightened on both sides. Every car seat has it’s positives and negatives, and the Britax Frontier 85 is no exception. Because of it’s size, weight and installation which several customers found cumbersome, it is not the ideal car seat for some, but we found an overwhelmingly high number of positive reviews for this unit.

Getting such a large number of users, each with different needs, different children, different vehicles and different levels of expertise in installing the seat, to agree on such high ratings mean that the Britax Frontier 85 is truly one of the top car seats available today.
