This car seat is really really nice! There is nothing that I dislike about it. When my child is sitting in it, he looks more comfortable than me. Its supports his head when he falls asleep and his head isn't flopping all around. Its also very VERY easy to install in the car. Takes less than 5 min! This is a wonderful carseat and worth the extra $$!!! I definitely will be purchasing for my next children!!!
So, if you are wondering if these carseats are way to over priced, they aren't!!! They are worth every dollar!!! So, go and buy one!!!
I have a Marathon Britax also and the Boulevard is so much easier to use! If I had to do it again I would get two Boulevard carseats! The Britax brand is such a good carseat though. Some are just easier then others!
