Like every mom, safety is so important to me when it comes to my children. There are numerous car seat options to choose from and if you do not do your research you can really miss out on some of the important details. I have been on the lookout for the perfect car seat for my growing 5 year old, but I also wanted something my 20 month old son could also use as well. Versatility is something I look for in almost everything I buy.

Car seats can be costly but a child’s safety is invaluable.  Car seats are one of the few items I purchase that I do not mind spending a pretty penny on if needed, although I was very glad that the Diono Radian RXT Car Seat is within our family’s budget because having two children means purchasing four car seats, two for each vehicle.

When researching car seats I am not looking for anything lavish or fancy. I want practicality and security over two cup holders and pretty flowers. The Radian RXT Car Seat is extremely versatile and has so many great aspects I am happy to share. Right from opening the box you can tell from the construction of the Diono Radian RXT that it is much sturdier and solid than any of our other car seats. This car seat is made with a long lifespan and narrow design allowing up to 3 car seats in one back seat, that is pretty amazing considering I previously had a hard time fitting two in the back of my Honda CRV without feeling crowded and overwhelmed.

The Radian also goes up to a 120lb booster, I mean that is pretty amazing. I will be one of those moms that keeps my child in a 5 point harness car seat for as long as possible, maybe even until High School if I can! Just kidding (kind of) but really you cannot put a price tag on safety. You may be the best driver in the world but you cannot control other drivers and unforeseen accidents and that is why it is so important to be prepared for any situation. I feel like this car seat is indestructible, it is one solid piece and the best constructed car seat I have seen to date. All prior car seats we have owned were designed out of plastic, well the Radiant is made of pure metal.

With every car seat we have purchased, we have always had questions, “why did they do that and why didn’t they do this?” Well, the Diono Radiant RXT answers all of these questions. It is some of the simple differences between the Radian and others that make it stand out so much for us.

A small but amazing feature is the buckle on the car seat. The buckle falls forward when not in use, it is so nice to not have to go searching under my daughters bottom once she has already sat down to find the buckle, simple right, but I’m all about convenience. When it’s hot, raining or I’m just purely exhausted from the day the last thing I need is to be lifting my 45lb toddler in search of the car seat buckle that should be right there.

Another one of my favorite features is the size of the buckles, they are huge! My daughter loves to buckle the top, she can wrap both her hands around it and when it snaps it feels very secure, it also makes a little spring sound (if you have a Radiant you know what I mean) my 5 year old loves to hear the spring sound, I’m not sure why but it is pretty funny.

Installing the Radiant was a piece of cake, literally I think I was eating snacks at the same time it was that easy!  Multi tasking mama over here! Though I have to admit I did need some initial help carrying it, it is a little heavy but I was also carrying my son at the same time. The latch system was easier to use than any other car seat we own. I was determined to install this car seat on my own and it took roughly 5 minutes, I’m obviously a car seat installing Ninja! I love that the Radiant has inserts that can be removed depending on the size of the child and adjustable seat bottom sides for a tighter fit. Since we use this car seat for both children it is great to have the option.

I have switched out my 5 year old and my 20 month old in the car seat and it literally takes less than a minute to make the adjustments needed, it is great! One of the best conveniences is not having to swap out car seats when picking or dropping off other kids from school.

As most parents experience at one time or another is car seat spills! Awful, hard to clean up and stressful to watch when driving and you see a massive milk shake or cup of juice just pour over the car seat. Well, the fabric on the Diono pretty much repels spills, I have never had an easier time cleaning a car seat and I’m being honest. I remember taking my daughters other car seats apart to wash the cover and literally wanted to cry, it was so much work to take on and off and such a hassle. Then you have to worry about installing the cover on the right way after. Anyway too much work for me and that is why the fabric on this car seat is so amazing. I was also told when I called Diono customer service that the fabrics used, Storm and Rugby have the least amount of required flame retardant chemicals, and this is a huge deal for us because again, I take into consideration all possibilities when it comes to child safety. They also have a new micro-mess velour fabric that is very comfortable for the kids and do not cause them to get too hot on a sizzling summer day.

I cannot wait to take the Radiant on a plane with us, we have not done any traveling recently but I am looking forward to testing out the air travel quality’s it has to offer. Not only does the car seat fold up but it has straps you can wear it like a backpack. The car seat is not light, so this was a huge plus that they added the back straps to help with this, especially at an airport when traveling. I really like that they put a lot of thought into considering many different situations for parents into this car seat.



The only minor weakness, if you can even call it that, is the cup holder that comes with the Diono Radian RXT. It is a little on the complicated side to install. Keep in mind that I do not like to read instructions; I’m super mom and can do everything on my own without it, right?  I could not find the slot to attach the cup holder for the life of me. It took longer to locate this than to install the car seat. I finally gave in and grabbed the instruction manual and then it literally took 2 seconds to attach. The little slits on the sides are a little concealed, which I actually like in the long run. Not a real flaw or big deal at all when you consider the total package you get with the Radiant.

When used as a booster without the harness, the seat expires 10 years from date of manufacture, when most car seats are 5-7 years. That is a huge difference! I honestly believe the Radiant is the safest car seat we now own and will set a new standard for car seat safety requirements. I wish Diono made adult car seats, we would all be in for a ride, a safe one that is!
