Safety Features Protect Your Child from Injury

The RadianRXT's design begins with a steel alloy frame for a foundation that stands strong while other features disseminate crash forces away from your child. Aluminum reinforced side walls and head support lined with thick, energy absorbing EPS foam provide excellent side impact protection. The SafeStop energy absorbing harness provides extra protection for children 20 to 40 pounds in the forward-facing position. When installed, SafeStop provides bungee-like energy absorption which reduces impact on the child. Additionally, the RadianRXT boasts rear-facing tether capability to reduce seat rotation during an impact.

This car seat surpasses Federal crash test standards and meets NCAP standards, the industry benchmark for verifying child seat performance in severe accident conditions. The RXT is tested at its maximum forward-facing, rear-facing, and booster weight capacities, and is rated for 10 years of life.

Adaptable Design Accommodates Growing Children

The RadianRXT can be adapted to your child as they grow, keeping their car rides safe and comfortable for year. From birth to booster, the RadianRXT fits children in the rear-facing position weighing from 5 to 45 pounds, and children in the forward-facing position weighing from 20 to 80 pounds. This model converts to a booster seat for kids up to 120 pounds.

An adjustable, reinforced head support offers 12 height settings to ensure the right fit for your child and provides additional side impact safety.

Comfortable Ride for Little Ones

All Radian seats have a deep shell that provides a more comfortable rear-facing ride, as well as a higher rear-facing capacity. This car seat features a plush cloth surface that feels soft against your little one's skin. Expandable sides and a longer seat bottom offer better leg support, and help keep children cozy as well as helping maintain a custom fit throughout their physical development. Two forward-facing recline positions allow the RadianRXT to fit a wide variety of vehicle seats. Body support cushions ensure infants and babies are safe, snug and positioned correctly.

Secure SuperLATCH Installation

Diono's SuperLATCH system allows LATCH use up to the full weight capacity of the car seat.* The SuperLATCH connectors are successfully crash tested at 45 pounds rear-facing and 80 pounds forward-facing. In vehicles with LATCH anchors SuperLATCH is a safe, convenient way to install the RadianRXT and provides a proper installation every time. Rubber bottom grips ensure the seat won't slide after installation and also protect your car's upholstery.

Compact Design and Easy Care

Thanks to its exceptionally slim profile, the RadianRXT can sit three across in most vehicles. Because it does not have a pedestal the seat sits relatively low, making child boarding easy. It also features a folding design, so storing or transporting the seat is easy. The car seat is FAA approved for use on airplanes. The machine washable cover and cup holder compatibility (up to four, one included) make this car seat even more convenient.

The Diono RadianRXT Convertible plus Booster Car Seat is backed by a manufacturer's one-year limited warranty.

5Review following major car accident! 

I was just in a major fwy car accident. Hit at 60mph and spun through three lanes of traffic with my kids (ages 1,2,&3) three across in this car seat. The kids did not move an inch and the car seats withheld the impact to a degree I never thought possible. My kids came out with no injuries aside from a tiny (1 inch) skin irritation from the strap on my only forward facing child on the side of impact.

5Incredibly thought through car seat 
 
We have 3 children ages 7, 3 and 3 months. I have used various seats from infant to booster over the years for my children. In addition to being an end user of these types of products, I am also an 18 year firefighter a major metro city fire department. I have seen more motor vehicle accidents involving children than I care to recall. My endorsement of this seat falls into two categories; first as a parent, second as an emergency worker.

As a parent this seat is extremely well thought through. If you've used other seats you have asked yourself "why didn't they do this?" you will have finally found the seat that answers that question. If you are new to car seats... you are making a very good choice.

Something as simple as having the buckle fall forward when not in use. Not having to dig out the buckle from under your child's rear end is genius. Big buckles that are easy for an adult for operate one handed. Our 3 year-old has been an escape artist in every other seat has finally met her match. The buckle is simply too big for her hands to manipulate simultaneously. One of the best conveniences is not having to swap out car seats when picking or dropping off other kids from school, practice, etc...

As an emergency responder these seats look like they are designed for a NASCAR. It seems to me that relatively, all car seats provide some reasonable protection during a crash. The incidents I have responded to that a child was injured was due to the child not being properly secured in the seat. This seat sets itself apart because it is very easy to buckle your child properly with one hand. No fishing around for buckles, no way for buckles to improperly latch (or not be latched).

We have placed our 3 year old and 3 month old in this seat. It takes less than a minute to make the necessary adjustments.

This is great, convenient seat that is very well engineered that will last a long time and accomadate one child through the years or adjust to many types of children that you may be transporting.

4Great seat, installation tricky in older cars. 

Unboxing:

First impressions of this car seat are daunting to say the least. I pulled it out of the box (a big box) and found I had to dig for the instructions right away. It comes in the collapsed mode, which allows you to attach straps and carry it as a backpack, very handy for traveling, say, on an airplane. By the way, this seat is fully airline compliant, so you shouldn't have any trouble bringing it on a plane.

Anyway, as per the directions, the base of the seat folds out for use, and does so via a simple-to-operate latch. The back of the car seat holds all the various LATCH straps and belts needed for installation either rear- or forward-facing, as well as a seat belt clip for cars built before 2001 that do not have a LATCH system. Also in the box are the backpack straps previously mentioned, as well as the infant padding you can see in the picture above, which will nicely snug in your newborn. Our son is now about 20 lbs and too big to need the extra padding.

First Impressions:

This Radian RXT is somewhat large, as you can see. Given that it can hold children all the way up to 120 lbs (which is heavier than some adults!), it should be. The headrest portion is adjustable so that the aluminum-framed head supports align correctly with your child's head.

Though tall, the seat is not especially wide, a feature Dioni says allows this seat to be installed 3-across in a vehicle. The construction is very strong and durable, composed of both heavy plastic as in most car seats and aluminum framing in certain places.

The straps are all adjustable of course, and this was the fastest part of setup for me, in contrast to many other car seats that make you remove covers and padding and whatnot; this was very straightforward to adjust to our toddler's height. A nice feature that complements the adjustable shoulder straps is the tensioner at the front of the seat which ratchets rather than just pulls, so you don't risk getting it too tight all at once when fitting it to your child.

It's a big plus to have a seat that you can take your baby home from the hospital in and not have to buy another seat until they're big enough to not need one any longer, so I was looking forward to installing it and trying it out.

Installation:

Installing the Radian RXT turned out to be very challenging with our two vehicles that I tried it in. The big disclaimer here is that unfortunately we don't have a modern SUV or minivan, so installation was doubtless more difficult than it would have been had we had one. I first tried installing it in our 2000 Isuzu Rodeo, which unfortunately does not have a LATCH system, and after struggling with it for about 30 minutes and reading the directions over and over, ultimately had to give up. The design of the seat is such that the belt path under the seat is a closed tunnel, which first of all means you need small hands to be able to thread the belts through, which wanted to get hung up inside. But once I got the seat belt through, a larger obstacle cropped up. Because the belt tunnel is so low and closed off from the top (unlike a traditional car seat base), I was unable to tighten the belt enough because the car buckle of course cannot bend around the angle of the tunnel. This was with the rear-facing base attachment properly secured, but it was still as if the belt tunnel was too low to be able to tighten the belt enough. Compounding this in a car without a LATCH system is the fact that you have to secure the belt clip and then fasten the seat belt. However, with the Radian, there was absolutely no way once I secured the belt clip to snake the tightened belt back through the tunnel and clip it into the buckle since you usually have to have lots of leverage to do that, and I'm sorry, but my fingertips just aren't strong enough to manage that.

So, on to option two, the BMW 3-series sedan. It's a 2001, so it does have a LATCH system fortunately. However, given the size of the Radian RXT, I found it couldn't be installed behind the driver's seat, which is where the current car seat goes, because the high headrest of the Radian would have meant that the drivers seat would have had to go forward too far for anyone except a little person. I'm sure it would have worked okay forward-facing, but we can't do that until the baby is bigger.

So I finally got it installed on the passenger side of the car, but seemed to have a similar problem tightening the LATCH straps, due to the belt tunnel seeming too low. But in actuality, when tightened down as absolutely as I could, the manual says that when gripped at the tunnel, the seat should not move more than an inch in any direction, which it doesn't. However, it didn't seem right at first because shaking the seat from the headrest resulted in a lot of play. I guess this is to be expected since there's lots of leverage there, it's just that the manual didn't say anything about how much the headrest could be expected to move, and it seemed like a lot compared to the compact car seat we were currently using.

Use:

So the installation was rough, and took almost an hour before it was finally installed. But once it was in, use is as simple as any other car seat, and the quality of the buckles across the chest and between the legs definitely seems a notch above. As mentioned earlier, all adjust easily and connect positively. I also liked how once our son was in there that it seemed more open and airy than a traditional car seat while holding him securely. In any case, I see no issues with further use, and I know it will prove to be an excellent car seat whenever we finally do get a modern minivan.

Final Thoughts:

The Radian RXT from Diono is very well-built and versatile. You could buy 2 or 3 car seats for your young one until they don't need them, or you could get the one Radian RXT. It's adjustability and quality of materials is definitely above par. I just wish the belt tunnel had been designed to make installation without a LATCH system less painless. That said, my difficulties with installation could just be that a fault of general ineptitude with car seats, mechanical prowess in many other areas notwithstanding, and not so much a fault with the seat. The Radian has lots of great reviews on Amazon, including one I read from a lady who has two in her Honda Civic, so maybe it was just a bad combination of an older car and installing while tired. In any case, the Radian RXT is a great carseat and one that I know will be able to handle all the abuse a baby/toddler/child can throw at it.
