A.P.
I was told the same thing about the Boulevard. I know someone who has it and although they really like it, they said it is extremely bulky, even over the Marathon. We actually bought the Marathon and we love it. He is so comfortable in it. He loves his new car seat. It is such a hard decision and a lot of money. I'm glad we bought it though. He falls asleep in it and looks so comfortable. Good luck!
