Might be a stupid question

Most of the time you can look at the stroller details on the box, or online, and it’ll tell you what specific car seat will click into it. Logically I’d assume that most brand car seats should click into the same brand stroller, but I’m not completely sure.

yes i think they usually say compatible with all such and such products

A lot of strollers come with adapters for different brand car seats. I have the uppa baby stroller and I know they make adapters for a lot of other brands. I would pick the stroller you want first and then figure out which adapters you can get to narrow down the car seat selection if you don't want the whole travel system.

Thanks ladies!

I just bought the travel system because it was cheaper as a bundle.
