With the announcement of the ClickTight Installation System in the 2015 models of the Marathon, Boulevard, and Advocate convertible carseats, Britax has indeed introduced a Game Changer into the convertible carseat market. Gone are the days of huffing and puffing and yanking on seat belts and LATCH straps to get carseats installed tightly. As technicians in the field, we know a loose install is one of the top 2 mistakes we’re going to see in a vehicle when it comes to a checkup event. ClickTight was a big deal with the Frontier 90 and is just as big of a deal for any carseat rated above 40 pounds or so, due to new federal standards limiting the use of the LATCH system.
Do these convertibles hold the cure for all possible misuse? Of course not. There may be some incompatibilities and the price may put it out of reach for many families but we can’t make advances in child passenger safety without advances in technology and those advances often come with a hefty price tag – at least initially. For that price tag, you also get increased height limits and a 10-year expiration date, so there is some value added!
Kecia, our lucky reporter in the field, got to touch and feel and see these cool new seats. We will have a full review coming in September. For now, she took a ton of pictures for us and a video and reports that baby Jack fits beautifully in the new Marathon without the lower body insert (see pics). With the lower body insert, the bottom harness slot measures about 6.5″.
These pics below show the preemie doll using the lower body insert. The Britax convertibles are rated from 5 lbs. to 40 lbs. rear-facing, so our 4 lb. Huggable Images preemie doll is too small to fit in any of them, but Kecia wanted to get an idea of harness slot fit.
The Marathon CT is going to be a smaller seat for Britax while the Boulevard CT and Advocate CT have a growth spurt (see photos below).
