Introduction

This review is for the Britax Frontier (now replaced by the Britax Frontier 85, please see our new review here). This is a “Harness-2Booster” or combination (combo) forward-facing child restraint and belt-positioning booster seat. Using the harness forward-facing, it is for children over 2 years, weight from 25 to 80 pounds and from 30 to 53 inches tall. As a booster, it is rated for children starting at a minimum of 40 pounds and 42 to 60 inches tall. In booster mode, there is no official maximum weight limit. If a child can otherwise meet the height limits and be properly positioned, it is possible to exceed 100 pounds for booster use.
