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.
- True Side Impact Protection distributes crash forces, shields from vehicle intrusion, contains the head and body, and keeps the head, neck and spine "in true" or aligned, to limit injury
- Highest Five-Point Harness Seat Capacity allows your child to remain harnessed up to 85 lbs or in booster mode to 120 lbs
- Quick-Adjust Head Restraint & No-Rethread Harness easily adjust the harness shoulder height and head restraint without disassembling the harness
Superior Energy Management
- Patented Versa-Tether introduces a staged-release tether webbing that anchors the top of the child seat at two points to minimize forward movement in a crash.
- Energy Absorbing Base deforms in the event of a crash to absorb impact forces
- Energy-Absorbing Foam Liner absorbs and distributes crash forces
- Harness Ultra Guard System, HUGS, reduces forward head movement in the event of impact
- 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)
Superior Fit and Comfort
- Tangle Free, 5-Point Harness with 10 harness height positions (up to 20") and three buckle positions for a snug and secure fit as your child grows
- Plush, Premium Cover Set with thick, underlying comfort foam provides extra comfort, encouraging your child to stay in the proper position
