It’s definitely not a feature I’d normally look for in a car seat for a Civic, unless there were a confounding situation that would make it worth the extra space. If your child is tall or heavy for his age, you’ll need to be more careful to pick out a seat that will last. Petite kids can have more options that will work. For a Civic, I’d probably look at a Graco Extend2Fit. It’s a bit wide but it’s fairly compact front-to-back and should be a good fit. A downside is that the door opening in a Civic is a little tight and the Graco has kind of high sides which can be annoying until the child can climb in with assistance. On the other hand, with the new side impact standards I’m having a hard time thinking of a current seat that will fit well in a Civic and *doesn’t* have high sides. Diono is the only one that comes to mind that hasn’t been discontinued yet, but it’s too much of a space hog to use in a side seat in a Civic. It *might* fit in the center, but the last time I used one in a Civic it was a 2005 model year and the back seats have changed a lot since then so I’m not sure how well it would work. It can be a kinda finicky car seat for installation.

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 have 98 and 99th percentile kids and Diono car seats have saved us so much. We had a Graco baby car seat with base even though the Diono has insert for infants. It was just easier to carry baby and we used it for both kids as the were close in age. They are giant 3 and 5yos now and with the long expiration date and weight limit of 120lbs, they’ll be in them until high school. Second hand baby Bjorn bouncer was amazing. Anything food or potty related get the least complicated smoothest surface area products for easy cleaning. Ikea high chair, little partners wooden booster seat, and one piece potty seat.

I’ll second this! I had three Diono seats in the back row of a Subaru outback for a few years. It worked rather well!

I have 3 of these across the back of my 2015 Outback. They are a little tight to go in but sit perfectly once in place.

We had 3 Diono Radian car seats fitting in the backseat of a Subaru crosstrek. What’s tricky is when you need some to be rear facing because they lean back far. For that situation they sell a piece of foam that slides under the seat to safely adjust the angle.

We bought a Diono Radian with a backpack travel bag. It folds up and is relatively portable. It’s definitely not lightweight or cheap, but it’s substantial enough to feel safe and we use it in our second car as an every day car seat. There’s cheaper and lighter options, but we’re semi regular travelers so having something solid and comfortable for the kid is worth the extra money and weight. The car seat is a lifesaver on the plane. It’s not explicitly required but strapping her into a familiar seat makes the experience way less stressful. There’s no chance she’d sit still without it.
