I have the Boulevard70cs and I love that seat. I debated a lot between the boulevard and advocate, but the advocate is bigger and I didn't want it taking up so much that if I wanted to put 3 across in my tahoe once in a while rather than using my 3rd row I wanted to make sure 3 across would fit. With the advocate it wouldn't. Both reguardless are good seats, just advocate is bigger width wise on top.
I was thinking of getting one for my daughter when the new baby is born, since she will be on the side then.
I absolutely love this seat! Especially how low the sides are. It's really easy to get them in and out of it. I have an 18 month old who often insists on doing everything himself, even getting in his carseat and the low sides make it easy for him to climb in.
This is the one I will want to buy when I have my own baby, do u like this car seat?
