I agree with Susan. The other thing is that with teh Marathon, you have a few more covers to choose from (for some people that is a BIG issue when purchasing a seat). With the Boulevard, you have a tendency to lose about 1/2" of height b/c of the headrest. The biggest problem with the Marathon is that there is only 1 crotch buckle position. So just some things to think about

	Britax Marathon - Click for more info Increasing the time a child can safely stay in their convertible car seat is a big issue and Britax engineers have come through in a big way with the introduction of the Britax Marathon with LATCH. A LATCH Compatible Convertible Child Seat, the Britax Marathon can be used rear facing 5 to 33 pounds and forward facing from 20 to 65 pounds. Compare the numbers and you will see it is hard to find a seat with these weight limits that is safe and functional.

	Britax Boulevard - Click for more info It is all about the wings with the Britax Boulevard convertible car seat - head and torso safety wings help keep your child from harm in a side-impact crash. And this matters - side-impact crashes are the leading cause of death for 6 - 14 year-old children. Of course, the safety wings are only one of the many safety features that the Britax Boulevard offers: built-in lock-offs, 5-point harness with front adjuster, tangle-free webbing, a push button release LATCH system with Versa-Tether®, and a sculpted base, ensuring an easy installation with a secure fit.
