True Side Impact Protection for Advanced Security
The Frontier 85 Combination Booster Seat is ideal for parents concerned with providing proper safety and posture-support for their children during car rides. Offering True Side Impact Protection, this seat delivers superior protection if you happen to face an unexpected side-impact accident.

If such an event takes place, the solid head support and deep side walls work efficiently to distribute forces, shield the child from vehicle intrusion, contain the head and body, and keep the head, neck, and spine aligned to limit injury.

Superior 360-Degree Protection Features
The Frontier 85 features an advanced, industry-leading design for crash force management and absorption. The patented Versa-Tether system provides a staged-release tether webbing that securely anchors the top of the child seat to your vehicle at two points to minimize forward movement in the event of a sudden stop.

The energy-absorbing base is designed to absorb impact forces, while the foam lining provides additional support. In addition, the Harness Ultra Guard System (HUGS) reduces forward head movement and offers increased protection for your child.

The Frontier 85 is also compatible with the SecureGuard feature. The optional SecureGuard clip holds the lap portion of the safety belt in place, preventing submarining--when the child slides under the lap belt--and reducing the risk of any abdominal injury.

Adaptable to Your Growing Child
The tangle-free, five-point harness allows for 10 harness-height positions--up to an industry-leading 20 inches in shoulder harness height--and three buckle positions for a snug, comfortable fit, even as your child grows. You can also adjust the head restraint with one hand using the quick-adjust lever and easily change the harness shoulder height without disassembling the entire harness. Plus, the convenient front harness adjuster allows you to loosen or tighten the harness system easily.

The booster seat can be used in the forward-facing harnessed position for children a minimum of two years old, weighing 25 to 85 pounds, the highest capacity in five-point harness systems. As a belt-positioning booster seat, the seat is suited for children from 40 to 120 pounds.

Easy-to-Install
The Frontier 85 allows for quick, easy installation with lower LATCH connectors, compatible with most current vehicles. The premium, push-button system provides a tight, secure fit and makes it simple to install or remove the seat.Your child will appreciate the armrests that provide a natural place to rest his or her arms along with the dual cup holders designed to hold reusable water bottles or snack containers.

Soft, Durable Material with Comfort Foam
The plush, premium cover set with underlying comfort foam makes for a comfortable ride, even during long car trips.

Made from soft, durable materials, the booster seat's cover is easy to remove from the shell for cleaning and is available in a selection of distinctive patterns, including Rushmore, Red Rock, Canyon, and Pink Sky.

This combination booster seat is backed by a limited one-year warranty.

Don't even blink at the price or anything else that really doesn't matter in the grand scheme of life. We were in a freeway rollover accident yesterday in our Honda Pilot that completely totalled the car. My precious 4 year old daughter was all strapped in tight in this carseat and walked away without even a scratch. As soon as I finish up this review, I am buying another one. Seriously, when you are in an accident like that, won't you be glad you put your munchkin in the safest seat possible, even if it can be a pain in the neck to install and annoying to get the cover off to clean? Also should note my 22 month old son was in an Evenflo Triumph (also gets high safety ratings). Thank God he was totally fine, but the strap that attaches the carseat to the anchor in the car literally ripped in half horizontally. It is a miracle that he is okay, because I shudder to think he could have been flopping around with only one anchor attached in addition to the over the seat tether...

I own several high weight harness seats, and this is my favorite! My son (5 yrs old, 47", and 43 lbs) has previously been in a Radian XT and a Graco Nautilus. He started to complain about the crotch strap being tight on both seats- I looked at it closer and it turns out the straps were coming out from underneath him even though they were on the furthest setting out- in both seats! We tried the Frontier 85 and he was much more comfortable- he has at least an inch or two until he'll be up against the crotch strap in the FN 85. I was worried about install, especially after reading about the original Frontier not installing well (or at all) in Toyotas. I had the FN 85 installed with the seatbelt in my '05 Highlander within 10 minutes, and that includes trying the short belt path first (I had to recline the seat and use the long belt path, but I have a rock solid install.) It really helps to watch the Britax install videos before trying to install it, as I could see how I would have had some trouble if I didn't watch the video first. The 9 year lifespan of the set is also a huge bonus!

Color Name: Rushmore
I own a Britax Marathon which I still use for my younger child, and had purchased the Britax Frontier 85 as a long term seat for my oldest child, currently 3 years old. Occasionally I need to remove the car seats and install in another vehicle. The Marathon can be done with ease. The Frontier, is the most frustrating installation I have ever experienced. I believe it is due to a cheaper design. The Marathon offers 2 independent straps for the latch system. Each is pulled individually for a taught fit. The Frontier however, only offers 1 pull strap for both latches. This may have saved $10 in design and construction costs per unit, but for the customer , far more a struggle than the Marathon design.

What makes it difficult is how incredibly easy it is for the strap to become twisted and tangled in an area behind the seat which you have no visual nor access to. I have read some of the positive reviews here and one individual was questioning intelligence for those that are having difficulty with the installation. I am a technical engineer by day with a master's degree, and can assure you, I am not lacking intelligence. I am also a volunteer firefighter, and have knowledge and experience on how to install, uninstall and in emergency situations, cut these seats in half.

Their customer service is what may save them from losing me as a customer. The representative acknowledged that if you pull taught when the strap is in a twisted state, that could cause it to want to twist during successive pulls. They are sending me a new set of straps to try. Ultimately I'd rather see an independent 2 strap design like the Marathon.

Color Name: Rushmore Verified Purchase
Automobiles are not built to protect small passengers in a crash - even small adults! If you want to increase the odds your child will survive a collision, I recommend keeping him or her in a booster seat as long as you are able to do so. The Britax Frontier 85 is more than just a booster - it is a booster with a top tether which significantly increases the safety of the seat. A 5-point harness is safer than the seat belt, and that's how my petite 9-year-old rides. The law says 8 or 80 but I feel that law should be more stringent. I plan to keep my daughter in the harness until she reaches 85 pounds and the belt-positioning booster until she is 12 or older. I have taught her that safety is more important than "image" - I don't care that all of her friends are allowed to ride in cars with no booster of any kind. The vehicle's seats and belts are NOT designed to protect your small riders. I'll say it again - a Britax Frontier 85 is well engineered to increase small riders' odds of survival in a collision.

I just bought and installed the Britax Frontier 85 yesterday. It was really easy to adjust the size to fit my son (3 and a half years, 43 inches, 41 pounds). I installed it in my Subaru Outback using the latch system, since the Subaru latch is rated to 60 pounds. It is really easy to do, the whole process took about 10 minutes. I switched him from a Boulevard, which took the same amount of time and ease to adjust and install. My only complaint with the install is that the lower latch only adjusts on one side, unlike my Boulevard, so the fit didn't seem quite as tight. I was able to crank my Boulevard so tight that if I shook it, my whole car would rock. The Frontier 85 is tight, just not quite as tight. Maybe it would be better if I used the seat belt instead of the latch.
We got the Rushmore color which is black and grey. It looks really nice, and the fabric is soft and high quality. My son really likes it because it looks a lot like a "big kid" booster seat. He loves the cup holders and arm rests. I love it because I am sure it is very safe, especially since my son can stay in a 5 point harness for a very long time with this seat. It is also very big, meaning my son can really grow with this seat, eventually using it as a straight booster seat using the seat belt. It is big, but it doesn't take up anymore space in my car than the Boulevard.
All in all, I am very happy with this seat so far!
