We’ve done it, it’s definitely tight but it’ll work with a compact car seat. There are several which specifically advertise 3 across, this is what we have… [Diono Radian 3R](https://store.diono.com/radian-3r-car-seat/)

Ditto on the Dionos, we have two and definitely appreciate their slim profiles.

I have 3 across, using the Diono 3R car seats, all fit perfectly. [Diono 3R](https://store.diono.ca/radian-3r/?srsltid=AfmBOoptd2pN7yiYauzznAjTRY3Cvf-_S9F-zQpSUZOn0ny4hLpgHAEB) Canadian link.

I used the litemax with my first and she was content in it. Later we got the Graco 4ever and she was okay with it but we got a third car seat the diono slim and she loves this one.

There's a Diono model that's approved for air travel that folds and isn't awful to carry. We had one, both my son and I loved it. We only replaced it due to an accident and needing a new one immediately.

We were happy with our Diono carseats for extended rear-face seating. Our strategy on strollers was to buy one that could convert from a single to a double. If I were to do it again, I'd buy a lightly used stroller from Marketplace or a consignment shop. So many baby things (and good quality) can be purchased secondhand. Friends who are done having kids are also VERY willing to give things away.
