Narrow vehicle, two convertible carseats? Ideas?


I have a Toyota Yaris and we're trying to find a good convertible car seat brand that doesn't take up so much room! Think coach, not first class throne.

We already have a Britax convertible for our 3 year old, and I'm skipping the infant seat (baby wearing), so any ideas? Mostly looking for actual experience with narrow seats, one can only read so many reviews, and they're all from people with average vehicles...
