this seat does fit 3 across and im sure it would fit in a narrow vehicle as well, however it does require a good amount of space infront of the seat when rear facing due to the back not being adjustable in height.

I bought this for my daughter and son in law as my baby grandson needed a new one as he outgrew the infant seat. They love it and would recommend it is anyone very impressed with it

I love the heaviness that is in the bottom of the car seat, letting me know that my kid will be secure because he is weighted down not just in a very white unsecured car seat. I don't think I will ever buy another brand.

Nice narrow carseat. Fits three across with two of these and one infant seat (it didn't even have to be in the center) my 2018 Kia Soul. Very happy with the purchase.

This car seat is incredibly sturdy. I feel like my little one is super safe. I love that I only need this one seat that adapts through to booster seat. And my daughter loves yet colour!

This is the second seat I've purchased. I now have one rear facing and one forward facing on our second row 60/40 bench seat but am still able to access the third row of our Honda Pilot.

Like this seat for the design and ease to pile in the kids , 3 to be exact. The other brands are bulky and wide making the ability difficult but with this one , it easily fits 3

I love that this car seat would fold at the base (it has 2 huge pins to lock it in place, and easy to retract), saving a lot a space when travelling by airplane.

I bought two of these. They fit perfect in my aviator and look nice as well. They are easy to install. I'd say they are heavier than a normal car seat but that's due to them not being made of pure plastic :)

We need narrow car seats to fit 3 across, and these fit well. I wish they did not contain flame retardants and other chemicals that are extremely harmful to children, but options for narrow car seats are very limited.
