Just what I was looking for!

 from Frisco, TX– Verified Buyer

After having my twins, I needed to be able to fit 3 carseats in the back of my Toyota Highlander. I bought 3 Diono Radians and the fit perfectly: 2 rear facing and 1 forward facing. This is a really solidly built seat and am happy about my purchases.

Love this seat!

 from Davenport, FL– Verified Buyer

I bought this car seat because we have a third baby on the way and were looking for a way to fit three car seats in my small SUV. I love this seat and so does my 17-month old daughter. We are currently using it as rear-facing and I love the versatility. Highly recommend!

Great car seat

 from Driftwood, TX– Verified Buyer

I am very pleased with this purchase. We bought two of these for my (underweight) 4 yr old and 2 yr old. The seats are very easy to set up and my children think they are pretty comfy. Win win!

Love it.

 from Albuquerque, NM– Verified Buyer

I love the narrow profile and the low sides. Simple, but has what you need! Fits great in our Corolla.

Very slim and easy to install

 from Jamaica Plain, MA– Verified Buyer– Top 500 Reviewer

This is the perfect seat for a snug back seat since it has slimmer sides and less depth than our Britax seat. It is a little heavier than the Britax toddler seats, but great for small cars.

 from champlain, NY– Verified Buyer

Love it. The RadianRXT receives 4.5 out of 5 stars based on more than 500 reviews. Users love that they can fit three of these seats in the backseat. They also comment on the tricky installation, and some complain that the straps are hard to tighten.
