RadianRXT Convertible plus Booster Car Seat (Cobalt) Product Image

Features

Steel Alloy Frame

Steel Alloy Frame Padded with EPS Foam Protects Your Child

The RadianRXT features a steel alloy frame for a strong foundation. Aluminum reinforced side walls and head support are lined with thick, energy absorbing EPS foam for side impact protection. The SafeStop energy absorbing harness provides extra protection for children 20 to 40 pounds. When installed, the harness's bungee-like energy absorption reduces impact when your child is seated in the forward-facing position. Additionally, the RadianRXT boasts rear-facing tether capability to reduce seat rotation in the event of an impact.

Accomodates Growing Children

Versatile Seat Grows With Your Child

The RadianRXT offers the adaptability you need to keep your child's car rides safe and comfortable. The seat fits children in the rear-facing position from 5 to 45 pounds and from 20 to 80 pounds in the forward-facing position. An adjustable, reinforced head support with 12 height settings ensures a custom fit and offers additional side impact safety. With longevity in mind, this model converts to a booster seat for kids up to 120 pounds.

Rear-Facing Position

Deep Seat Design and Plush Cover for a Comfy Ride

All Radian seats have a deep shell to cradle your child for a more comfortable rear-facing ride and to provide a higher rear-facing capacity. A plush cloth surface feels soft against your little one's skin. Expandable sides and a longer seat bottom offer better leg support and help keep children cradled in a custom fit that adapts throughout their physical development. Two forward-facing recline positions allow the RadianRXT to fit a wide variety of vehicle seats. Body support cushions keep infants and babies snug and positioned correctly.

SuperLATCH Installation

SuperLATCH Feature for Secure Installation

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

Compact Design

Slim Profile and Convenient Features

A slim profile means the RadianRXT can sit three across in most vehicles. Because it doesn't have a pedestal, the seat sits relatively low which allows the child to board with ease. The seat folds up when not in use, so storing or transporting the seat is easy. The machine-washable cover and cup holder compatibility (one included, you can add up to four per seat) make this car seat even more convenient.

NCAP Crash Tested

Testing and Warranty Information

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 an impressive 10 years of life. The car seat is also FAA approved for use on airplanes. The Diono RadianRXT Birth to Booster Car Seat is backed by a manufacturer's limited one-year warranty.

Product Description

The Diono RadianRXT is a highly versatile car seat that could be the only seat you'll ever need. It comfortably seats rear-facing children from 5-45 lbs, forward-facing children from 20-80 lbs in 5-point harness, then converts to a booster for children up to 120 lbs. It's built for strength and safety with a steel alloy frame, reinforced sidewalls, adjustable head support and our patented SafeStop energy absorbing harness. EPS foam surrounds the child's head and body to provide complete side impact protection. Our unique SuperLATCH system makes installation easy.

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. The RadianRXT sits low on a vehicle seat for easy child boarding, features memory foam padding and infant support pillows. Expandable sides and a longer seat bottom provide extra room and comfort for your growing child. One cup holder is included, with the option to add up to 4 cup holders. In addition to all this versatility, it folds flat for travel and storage, has a 10 year life and offers amazing safety, comfort and convenience your child won't outgrow.

We've had out Radian for a little over a year now. Bought it when my daughter was 10 months old. Reviews from friends were awesome. Said this is the way to go. My other daughter has a Recaro. and this by far surpasses the Recaro!! the extended rear facing and the angle adjuster option are a huge plus. Also, the size is wonderful. They are so slim, which makes them way less bulky in my opinion. we'd buy another in a heart beat. Diono also has awesome customer service! Looking for a car seat from birth to booster. Never having to buy another? This is the one for you!

I had to do my research on the best carseat for our family since I have a smaller car ('05 Toyota Corolla)--and realized that I may have an issue with giving the front passenger enough leg room for them to be somewhat comfortable. After thorough research for the best type of carseats for compact cars, it came down to the Diono Radian RXT and a competitor brand. While I wasn't keen on the price (paid over $550 for two for our two vehicles), I felt that it was the right fit for our family based on the exceptional reviews I had read about, espeically for the safety reasons. My gripe with this carseat is that once my son is in it (currently it is rear facing) and I pull up on the strap to tighten him in, the straps NEVER get tight enough. At first I thought that maybe it was the way I installed it, so I uninstalled it, checked the straps and reinstalled it. Again, I have to pull so hard on the strap that I can literally make my car rock back and forth! I thought maybe it was just the angle that it happened to be in while in my car, but when I tried the strap on the seat in my husband's car (Mercury Mariner), it was even worse! You can barely pull up on the strap--it's almost like something is getting caught and won't let you pull up on it, but there's nothing in the way, so I don't know why it's so hard. To "fix" this, I have to pull on the (exposed) straps in the back to get the slack tightened and then at the same time, pull up on the strap to get rid of the slack. I cringe everytime I put my son in it and wish that I had never bought them. Another reason why I bought them was because it was rated to 120 pounds and that it would have to be the only car seat I buy. Instead of thinking that this is the only car seat I'll have to buy, I'm debating if I should purchase new ones--and who has the money to do that all over again...To make matters worse, we moved at the same time and of course threw out the boxes, so returning them wasn't an option. Overall, I was very excited to get them, but disappointed once they were installed.

Great Car Seat!!

By julieR

Comments about Diono Radian RXT Convertible Car Seat - Cobalt:

This is the 3rd Diono RXT that I own. I have three granddaughters ages 20 months to 5 1/2 and this car seat is perfect for them, and will last them until they are no longer in need of seats. I particularly like that with my arthritic fingers, I can get them into and out of the belts and buckles without too much difficulty! Love them!

Comments about Diono Radian RXT Convertible Car Seat - Cobalt:

I bought this about a month ago and I love it! We have a smaller car and it fits great Facing backwards! There is plenty of room on the passenger side for a passenger in the front seat. The seat looks intimidating to install but once you do it one time it's easy. This car seat is a great size width wise too and doesn't take up an obscene amout of space in the backseat. It's a very sturdy car seat as well and I am very happy with our purchase.

Comments about Diono Radian RXT Convertible Car Seat - Cobalt:

I have had this seat for about 16 months. I bought to rear face my son longer and we have loved this seat. The low sides have been amazing for loading and unloading whether I do it or he does. I moved him to a combination seat for his 4th birthday and bought a plum cover for my two year old. She has always enjoyed it herself. She usually rides in a Guide 65 or a Nextfit and would always smile and laugh when I put her in her brother's seat (my kids have almost the same seated height which helps). I love the RXT and my kids have never experienced head drooping even though we use it with the angle adjuster (absolute must if child meets necessary criteria... major space savor) because they rest their heads on the wings. Of course it is heavy. It's a high end seat which all seats that are, are about the same weight. The big harness pads are little odd to work with but I have learned a lot about the little quirks this seat has from the Facebook group Car Seats For The Littles. This seat is very low profile so I had a few issues when first installing with a seatbelt in my Equinox since it has long belt stalks but a few twists of the female end of the belt solved my issue. I have 9 car seats and have owned more all of different brands whether they be cheap or higher end brand seats (Safety 1st, Evenflo, Britax, Chicco and Combi) and this has been my favorite.

Wonderful seat

By FrozenMom

from Arkansas, United States

Comments about Diono Radian RXT Convertible Car Seat - Cobalt:

I originally bought a RXT to keep my 16 month old daughter rear facing for longer than her britax would allow. I love the way Diono makes their seats! It is heavy and solid and feels like your child is very protected. My 2.5 year old niece was in a graco the felt flimsy after installing and I could move the sides of the seat in with my hands. It was in no way the same caliber as the rxt. My niece cried and begged to use the "cool and pretty" seat. So I bought a Rainier for my daughter and now both my daughter and niece are rear facing in Dionos. I am so happy with both car seats, wish I would have gotten these before buying any other.

great slim profile

By babyphat013

from Fredericksburg, VA, United States

Comments about Diono Radian RXT Convertible Car Seat - Cobalt:

We bought this with 3rd child on the way. After trying multiple carseats this was the only one to fit with our other 2 car seats, one infant Chico, and other convertible evenflo. Very good quality, easy for my 3 year old to get in and out of. Only con is its heavy and takes up lots of driver side space if using it rear facing.

By sem17

from Ft Lauderdale, FL, United States

Comments about Diono Radian RXT Convertible Car Seat - Cobalt:

Works great. My child is comfortable as she has already taken a handful of naps in the car since installing it. Only thing if the seat is intended to use the foam block/ adjuster it should probably come with one. However I have read that people end up ordering more after only a few months as it will flatten and so I ended up using a sturdy cotton rug folded to give the same affect to lift the seat up & so far its doing the trick. Either way I would buy this seat again for my next child.

We've had our radian rxt for about a year now and my toddler has no complaints. Its got great rearfacing limits and its so compact with the angle adjuster. I called customer service to get different straps and they were amazingly helpful.
