The new 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.
Featuring an innovative design and industry-leading technology, the Britax Frontier 85 Combination Booster Seat keeps your child safe and secure during car trips. Offering True Side Impact Protection and a patented, energy-absorbing Versa-Tether, this seat is engineered to grow with you child. The Frontier 85 accommodates children starting at 2 years old and 25 pounds up to 85 pounds when used as a forward-facing harnessed seat, and 40 to 120 pounds when used as a booster seat.
The high weight capacity allows your child to remain in a 5-point harness up to 85 pounds, or in booster mode to 120 pounds. (Shown here in Rushmore.) View larger.

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.
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 Canyon, Red Rock, Rushmore, Pink Sky, Cowmooflage, Maui Blue, Onyx, and Livia.
This combination booster seat is backed by a limited one-year warranty.

Love the Britax! Excellent car seat. It's comfortable for my son and love that it has a 5 pt harness and also can be used as a booster.
Not too heavy, but very sturdy.
Wife was t-boned and rolled the car a month ago with my 5 year old in this seat and she was fine. I'd buy another but we replaced it with a Radian RXT because we have a third child... Read morePublished 3 months ago by Joe
