Great seat, fits 3 across the back easily
Love this carseat, it's the reason I have been able to keep my car and fit all three kids in the back!

Expensive, but worth the space & easy to clean
This car seat is not cheap. Sometimes it goes on sale up to 15% off, which makes it easier to swallow. But if you use every day for 4 years, it doesn't cost much per use ;) I love that I can still split my car seats 60% (all other seats, I can only split 40%) and can fit 2 adults in the back with it (tightly). Unfortunately, you have to buy the $12 foam pad, but it's 100% worth the 3-4 inches of leg room you get (and my son prefers to be able to sit more upright so he can play)

This was our first car seat purchase and I haven't found one comparable yet! I feel confident that my child is safe in this seat and it is easy to install and adjust, unlike other cheaper brands we have purchased. We will definitely be sticking to Diono for our next car seat purchases!

By far the best for older ff'ing
We love the radian which allows us to fit our big family in a full van safely! My near 7-year-old still fits with growing room and allows her the utmost safety. We put the radians in the lap belt positions with plenty of space for the other kids and carseats! It is heavy but sturdy and safe.

great seat.
Love this car seat and its slim forward facing. However when rear facing need to use the angle adjust so that the passenger seat can still be used. Which there was a feature on the seat to adjust angle other them jacking to always buy the angle adjuster every couple months.

We bought two to fit in the back of a Honda CRV. The seats go side by side leaving space on medium to small adult by one of the doors- just what we needed to avoid going to a mini-van. Right now we have one forward and the other rear facing. The quality and smart design can been seen and felt right away. Very happy.

We have great confidence in this carseat
Before purchasing we extensively researched car seats and eventually came to choose this one. Based on reviews and safety standards as well as price range, this was our best option. So far it has been great and as a bonus very comfortable for our son.

Excellent Value!
We initially looked into Diono car seats for the narrow build - we drive a 2DR Yaris Hatchback - since we don't have much space in the backseat at all. We very quickly learned that the extra space the seat gives us is just the beginning of the many pluses that come along with this seat. Our 11 month old fits in it perfectly despite the fact that she is quite small and the steel frame makes me feel that much more confident in her safety. All in all an excellent seat!
