Cited as a "Best Bet" by the Insurance Institute for Highway Safety for its belt fit.
Awarded 4/5 (high back booster) and 5/5 (5-point harness) stars by the National Highway Traffic Safety Administration for ease of use (2009).
ZRecs recommends boosters only for children ages six and up who are mature enough to sit still in a booster seat, and encourages the use of boosters with side impact protection as long as feasible.
From Z Recommends: In addition to its harness-to-booster design, the Frontier features significant side impact protection, uncommon in car seats in general and almost unheard of in booster seats. The Frontier keeps kids harnessed up to 80 pounds and 53” tall (standing height), at which point you can remove the five-point harness and use the seat as a belt-positioning booster until up to 100 pounds and 60” tall. This seat has an astonishing usable lifespan of 9 years, which means that the Frontier is truly a second car seat that can transition your child from convertible car seat to a height sufficient for the safest use of shoulder safety belts without the need for a separate booster purchase. | Full review
