When we talk about safety, that’s where Diono really starts to break away from the pack…

Family Wheels

The Diono radian models have built a reputation on being narrow and working well in a lot of 3-across scenarios.


Outnumbered but loving every stage

Purchasing car seats is an investment. Finding a multi-stage design that accommodates growing children and growing families can deliver cost-savings without sacrificing safety, comfort or usage lifespan.

Fits 3 Across

As a mother to five children, I can’t stress how much I love these seats.

We did have to have 3 across in our car for over a year. We had 2 FF and one RF with no issues.

It isn't the cheapest car seat. However, it is the best car seat. You can't put a price on your kid's safety. So, all in all, this Diono Radian 5 car seat is a 10 out of 10, 5 stars, two thumbs up. Can't knock it at all. It's the best car seat we've ever had. Brilliant!

Luke @ Blended Parent Network

Overall, this is a great car seat which is comfortable, durable, safe and long lasting. To add to this, it has a 10 year warranty. We just wish we'd had it from when our daughter was a newborn!
