Diono RadianRXT Car Seat Review

I don’t compromise when it comes to buying car seats. I do my research. I talk to other parents and read online reviews and ratings. I look for the best seat that will fit my car and my children. One seat that fits my high standards is the convertible RadianRXT from Diono.

I received a RadianRXT from Diono for review. When it arrived I loved the look and color of it. The sleek body is a perfect fit for my Toyota Rav4. Of course the most important aspects of the seat are the safety features. The RadianRXT is NCAP crash tested, the industry benchmark for verifying child seat performance in severe accident conditions, and the only car seat rated for LATCH use with a child up to 80 lbs. It has steel alloy frame and aluminum reinforced sides, a Safestop® energy-absorbing harness system, an adjustable head support, reinforced for complete side impact safety and energy-absorbing EPS foam panels on all sides. The RadianRXT also sits low on a vehicle seat for easy child boarding (a great feature now that my oldest can climb in himself). One cup holder is included, with the option to add up to 3 additional cup holders and there’s even a slot that holds emergency information about your child in the event of an accident. And once my oldest hits the height and weight requirements, we can convert the RadianRXT to a booster seat. In addition, it also folds flat for travel and storage and has a 10 year life span. Installation was a breeze – the LATCH system took only minutes to complete. My oldest was very comfortable in the seat and I like that it sits him a bit more upright than his previous seats. The RadianRXT sells online and in retail stores for about $250.

    i also think the car seat for children is extremely important. This is the major thing that is going to help prevent injuries in an automobile accident. I have found that the full seat car seats such as this work very well as opposed to the booster seats that simply boost them up a little..

  2. Sue Morris says

    This car seat looks like a great one. I have 4 grandchildren using car seats and this would make some great gifts to their parents. Thank you for the review.

      Actually, that’s not his old seat in the background, it just was a coincidence that the seat was there at the time of this picture – that was actually an old car seat that was in my parents garage that we were getting rid of for them. We had him in a different convertible seat that we received last year that we are using now for my youngest son.

    We need to protect our children with car seats , they are not all the same. I like this one because in can be changed into a booster seat once needed. Till you buy an infant one and so on your spending more that what this one cost. The sides of the car seat are nice and padded to which helps protect the head and neck . Thanks for the review

    My daughter commutes to work with me 5 days a week. Her sitter is about a block from where I work. The bad part is that we have a daily 2 hour commute. I’m always looking for a good car seat to purchase. This one looks very safe and comfortable. I an not familiar with Diono (until now…)

    I spent so much time and effort picking out my baby’s car seat before he was born. I will be starting soon to find his next step up. Car seat research is so important, and I really appreciate hearing about brands and styles to add to my research list. Thanks!
