Diono - Radian 3R

We have 4 kids and both a mini van (love!) and just bought a model Y after testing out self driving (addicted immediately). Our kids are 3, 5, 7, 11. Configuration is: high back booster (Dionio 3R), and two convertible narrow car seats (Graco Slimfit3 LX). This works for us perfectly as the Graco’s work for all three younger kids, and the booster works for both of the older two, so at this stage we have everyone covered. I disabled the rear screen immediately so they don’t pay much attention to it. Bought seat back covers for the front seats. Full disclosure it’s cozy back there but worth it for me as a daily commuter/school drop off vehicle. Still love our mini van (Sienna hybrid) but as a person who hates driving, the FSD is a dream and worth it.

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.

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.

Currently have 3 slim (Diono) car seats in the back of our Outback and the back our a smaller Crosstrek. I thought we needed a new car but new car seats was a much better solution for us.

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.

I have three boosters in my ‘24 and it is tight. Three full-size, double cupholder childseat Britax will not fit (have them and tried). To get the fit you have to buy special slim seats and I’ll second the mentioned Diono brand.

I have the Diono brand

Wife has all graycos in her SUV. I liked the diono better so went with that for my truck. Now she likes those better and also wants them for her car… sure let’s spend another $600 on car seats

Currently have a Silverado 2500 and there’s some room still, but the gladiator cab is obviously a bit smaller

I three Diono R3s. That’s about as slim as they come. Currently have a Silverado 2500 which has plenty of room. But if I downsized it would be between a Gladiator and maybe a Colorado.

We have a Nuna exec at home but we're traveling for the first time with our new diono r3. You need to purchase straps but it can be carried like a backpack. It doesn't fit rear facing in economy on an airplane, but it works rear facing or front facing for cars and it's super easy to install. We like it for what it is. Our big guy fits in it with room to Grow

We have a travel car seat - the diono r3 - and you can buy straps for it that effectively make it into a backpack. We've used it domestically and internationally and it fits on coach seats (front facing) and then you can use it rear facing for the car once you get where you're going. Every time we travel with it, we have parents stopping us and asking about it. Super light weight and easy to use!
