I’m a little confused too! The Britax website shows the boulevard allowing up to a 49” child. Wouldn’t that make it seat a taller child than the Graco? I like the Graco except that the Britax has steel supports rather than plastic in the Graco. Anyone have any knowledge on how safe the plastic supports are? The Clek looks nice, but I’m afraid that my son is a little too small for it right now and it doesn’t have any support for smaller babies (he just turned 5 months).
49" is not the rear-facing height limit.
Here is an example: My DS will be 2.5 on Feb 10th. He is approximately 36" and 32 lbs. He has a 14" torso (from bum to shoulder). He might get to 3 rear-facing in our Boulevard 70s. He would probably easily make it to 5, if not longer in our My Size 70.
If you are on fb, then I would highly suggest you join the Car Seats for the Littles page. There are a ton of techs on the page that can help you, including myself. Plus, there are a million photos of different seats and different kids, which helps visualize what I am talking about.
Britax will be one of the last seats recommended because of their shorter shells.
