The FRONTIER 90 Combination Harness-2-Booster Seat features the ground-breaking ClickTight Installation System combined with BRITAX’s leading Head Safety Technologies
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
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
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
HUGS (Harness Ultra Guard System) Chest Pads provide resistance to forward movement in the event of a crash
Compatible with SecureGuard which works with the vehicle safety belt in booster mode to prevent the child from sliding under the lap-belt portion of the safety belt during impact, thus minimizing the risk of abdominal injury (accessory sold separately)

The Britax Frontier 85 Combination Harness-2-Booster™ boasts best-in-class forward-facing five-point harnessed weight capacity up to 85 pounds with an industry-leading 20 inch shoulder harness height. The seat also serves as a vehicle belt-positioning booster up to 120 pounds. Featuring True Side Impact Protection with one-hand adjustable harness height system, Versa-Tether and engineered energy management zones, the Frontier 85 is designed to be the safest high capacity seat in the industry. Loaded with comfort and convenience features, such as comfort foam, integrated cup holders and fixed armrests, the Frontier 85 is the ideal seat for the child graduating from their convertible car seat without compromising safety
The Frontier 85 features a five-point harness system is designed to make contact with the strongest parts of the body – the hips and shoulders, and transfer crash forces over those strong parts of the body. At Britax we understand that children are safer in a five-point harness and that is why we have created seats with internal harness systems that accommodate children up to 85 pounds. At Britax, we have always incorporated five-point harness systems in our seats. The first seat that Britax brought to North America, the Freeway in 1996, incorporated a five-point harness.
The Britax Frontier 85 Convertible Car Seat was Made in the USA with U.S. and global components.

(*A) What is the SecureGuard?
SecureGuard is an easy-to-use Britax exclusive feature that works with the vehicle safety belt to prevent the child from sliding under the lap belt portion of the safety belt (submarining) during impact. The SecureGuard clip slides over the lap belt portion of a lap-shoulder seat belt to keep the lap belt properly positioned low across the childs hips/upper thighs, preventing the child from submarining under the belt during a crash or the belt riding up into the childs abdomen. The purpose of a belt-positioning booster seat is to lift or position a child so that the vehicle seat belt fits across the strongest parts of the childs body.
(*B) What is the Tangle Free, 5-Point Harness?
A five-point harness system is comprised of straps or webbing that extend over your child’s hips, shoulders/collar bones, and between their legs. It is is located on the front of the seat where you secure your child. Seats need a Five-Point Harness System because injuries occur when crash force energy comes in contact with your child. Energy cannot be destroyed; it can only be managed or diverted away from your child. Incorporating a five-point harness in the seat allows the energy to be diverted away from your child over five points of contact with the seat.
(*C) What is the Patented, Energy-Absorbing Versa-Tether?
The Britax energy-absorbing Versa-Tether is a strap (a.k.a. webbing) that is attached to two points on the upper part of the child seat; there is a hook on this strap that attaches to an anchor in your vehicle. The Britax tether system allows you to tether your child seat in either the rear-facing or forward-facing modes. The Versa-Tether strap is located on the back, upper-part of the seat.
(*D) What is the HUGS™ (Harness Ultra Guard System)?
HUGS stands for “Harness Ultra-Guard System” which are chest pads made of a rubber-like material with treads on the back side. HUGS are located on the chest area of the harness straps for our higher weight capacity seats such as our 65 pound convertible car seats, our 80 pound Frontier combination Harness-2-Booster seat, and our 80 pound Regent forward-facing only seat.
(*E) What is the Energy-Absorbing Foam Liner (EPS)?
EPS foam is Expanded Poly-Styrene foam, which is the same foam found in bicycle helmets. Specifically, EPS is a closed cell, lightweight and resilient foamed plastic composed of hydrogen and carbon atoms designed to withstand an impact while dampening impact forces. When your child comes into contact with the EPS foam during a crash, the EPS foam deforms. At the point of contact, the air-filled EPS foam cells are crushed and the crash force energy is then diverted away from your child. The foam also acts as a barrier between your child and the rigid seat shell and any other objects that may intrude during a crash such as the vehicle door or window.
(*F) What is the Premium, Push-Button Lower LATCH Connectors?
The Premium LATCH connectors refer to the push-button lower connectors found on Britax child seats that allow you to install the seat into the vehicle using the LATCH system. The connectors are part of the child seat LATCH system that attaches to the lower LATCH anchor in your vehicle. An audible click can be heard when the connector is securely attached into place. Visit our About LATCH page to learn more about the entire LATCH system. The job of a car seat is to limit injury to your child. One of the ways in which the seat limits injury to your child is by minimizing movement of the seat from side to side and front to back. A tight installation limits movement of the child seat and therefore limits movement of your child during a crash. There are a couple of different ways to install your child seat into your vehicle. Using the LATCH system is one of those ways.
