I'm debating which one to get, and the only difference between them is the extra side impact head protection on the Boulevard.
If you have one or the other, did you consider another model? Do you think the extra side impact cushioning is worth it? (We do have side curtain airbags in the vehicle this seat would be in, but because of size, we always have to put rear facing seats on the passenger side of the car....)
Re: Anyone choose between Britax Marathon and Boulevard?
we got the Marathon b/c it was on sale on Albeebaby.com
When we bought DD's convertible seat last year, we picked the Boulevard over the Marathon because it had a better shoulder harness adjustment and I liked the head protection so that DD would have something to lean against if she fell asleep. But in the current models, it looks like the Marathon has the same shoulder harness adjustment and it curves around at the head enough that it might be a good enough headrest. I don't think the extra side impact cushioning makes the Blvd necessarily a better choice in and of itself. Since they're so much the same now, I'd go with whichever you can get for a better price, esp. with a site like albeebaby.
we got the Marathon, but I actually haven't liked it very much. maybe we just got a dud, but I find it really hard to tighten the straps. we've been using it for almost 2 years now and I really want to replace it. At first I thought that it was just a pain because of it being rear-facing, but now that we have turned him around, it's still hard.
