I have the stroller and the b safe car seat.
When I was registering for this the travel system was sold out online & wasn't in stores. So mine were purchased separately. Now it's in stores!
I love it.
I just have a base in my car as the manual says you can install the car seat without the base. DH works late, so i'll have baby most of the day so we figured we'd save 80 dollars and just keep the base in my car.
as PP said, the stroller comes with the adapters for the infant seat [which at first i didn't know until i saw the travel system in the store last month. I thought I had to buy an adapter myself.]
So excited to use these two items!
