Conclusion: The Britax Frontier 90 is a worthwhile investment, reviewers say. The harness-to-booster seat has a long life span with some of the highest weight and height limits on the market, and it's a snap to install using the new "ClickTight" system. The seat is an especially good pick for taller or wider kids, experts say. But reviewers note it's heavy and bulky, and several parents complain that the fabric cover comes off the seat base too easily.
Pros: Converts from harness to booster seat, Easy to install, Front-adjust, no-rethread harness, High weight and height limits
Cons: Heavy, bulky, Seat-cover fabric can separate from base
Britax Frontier 90 Review: Photos, Videos, Features and ClickTight Installation
3 May 2013
Conclusion: With a return to seatbelt installations inevitable for high weight harness combination carseats, the ClickTight system on the Britax Frontier 90 is just plain awesome. The trickiest part of using it the first time is simply locating it behind the cover! While many advocates loved the long belt path installation of the previous Frontier models, there is no denying that it was complex and sometimes a 2-person task for most parents.
Pros: Generous 20.5″ harness height, best in class!, Front height adjustment usable even when installed, ClickTight system seatbelt installations easier than LATCH!, Deep side impact wings for head and torso (photo, right), Reasonably tall booster mode provides good fit, EZ-Buckle keeps the harness buckle easy to find, Made in USA with IMMI harness components, Two position recline in harness mode, 9-year Lifespan, One word: Zebra, Harness adjuster hard to find at first for...
Cons: Harness adjuster hard to find at first for short fingers, but this makes it hard for kids to inadvertently loosen themselves, LATCH limited to 40 lbs., but who needs LATCH with ClickTight?, Relatively large and heavy, as are most combination seats, Relatively expensive, Not suitable for aircraft use, Not suitable for pet use (photo, right)
