Great seat if you need to fit three car seats in one row
June 8, 2014
I have a four year old and twin 1 year olds. I originally bought two rear facing only seats for my twins (had to do some research to find three that would all fit in my car). Now that I moved my twins to forward facing I had to purchase another two seats for them that would fit along with the booster I have for my four year old. These seats are narrow enough to easily fit three across either forward facing OR rear facing. I have one fairy wide booster seat + two Radians and while its a bit tight, it easily works. I've also moved all three to different cars and it fit all of them without issues. If I had three Radians it would be even be easier (since my booster is a few inches wider than these seats). My kids like the seats, seem comfortable to them, and are easy to buckle them in with. I didn't try rear facing with the kids in them, but I put them in the car just to see and space was ok that was too. I currently have 10 car seats including my two Radians, and these are one of the easiest ones to install of the bunch.If you are looking to fit three kids in a standard car (I have a Tucson and an Altima), I would recommend going with these. My only regret is that I didn't purchase these originally instead of buying separate infant carriers.
Prosfits three across in a standard size vehicle (Camry, Fusion, Altima, etc). Rear facing OR front facing. Easy to install Easy to buckle children in Seems comfortable

This is the 5th car seat we have purchased over the last few years and we bought it mainly based on size reviews. This is a very narrow carseat compared to others we have used (Graco and safety 1st being the other ones). We have it rear facing for the next few months until our child is large enough to be forward facing. We have it in our van and there is barely enough room to fit it behind my seat. It would not fit behind my husband's as he needs the seat all the way back. It is HEAVY though. Be aware. It is not a seat you want to be transfering often from vehicles. It was very easy to assemble. Took maybe 15 minutes, and the straps will be simple to adjust as child grows. We are very happy with the purchase and will probably buy another one to replace our other child's seat because of the narrow size.
ProsEasy assembly and install. Looks to be easy to remove cover and clean as well.
ConsNot ideal as a transfer car seat from car to car as it is heavy and bulky to carry. However it does fold up for carrying.

I don‚€™t recommend for rearfacing. It takes up a lot of room front to back so my husband can‚€™t deive my car.
Forward facing is great, and I like how long the seat lasts before expiration

Great Seat!
September 20, 2019
I am very pleased with this seat so far. It is big, but the angle adjuster did help to give me a little more room up front. A lot of folks complained about the install, but I didn't have much issue - I read the directions and got everything set up before hand, and it just takes a little muscle but not really more than I was expecting for any seat. My baby seems to like it. He use to get upset about being in the infant bucket, but he seems to feel less pinned down in this due tot he lower sides and he can look around and see out the window well. Because of the lower sides, I don't have to adjust the harness as much to get him in and out.

September 18, 2019
I love this carseat so much. I love that it is slimmer than most and less of a "bowl" to put your child in, making it so much easier to get my son in and out of it. I also love the ratchet tightening function as well so I dont have to struggle as much to tighten the straps. I bought this carseat for my first son and when it came to my second son, it was the easiest decision to buy a second one. I highly recommend this seat!
ProsEasy to get your child in and out Easy to tighten and loosen straps Slim profile

Our favorite car seat!
September 13, 2019
For the last three years we‚€™ve had Diono Raniers and absolutely loved them. Baby number three is due in November so we ordered these seats to be able to fit three across in our Dodge Journey. We‚€™ve not gotten much use out of them yet but our experience with Diono seats and products has been amazing. Easy to clean and great diono brand extras like seat protectors and angle adjusters. They are a little long front to back in our vehicle when rear facing without the angle adjuster, but with it my husband and I (5‚€™10‚€ and 5‚€™4‚€) can ride comfortably. We won‚€™t use our third seat until the baby is a bit older but we were able to still manage 2 of these seats and an infant carrier and it all fits perfectly. Our three and four year old kids love their new seats as well. They aren‚€™t the least bit cramped even though these are a bit more narrow than the Raniers. Highly recommend Diono!

Very easy to install! My 5 year old can still use the harness, and there‚€™s room to grow! I wish I bought this car seat when he was an infant it would‚€™ve been the only one he needs! Definitely recommend, especially if you need a narrow car seat that is comfortable for a child!

September 11, 2019
This carseat is beyond ny expectations. For a compact car, THIS IS HEAVEN! it is very heavy, if you move it from car to car i wouldnt choose this one. I got this one to stay in place in my car, her old one we move around because its a lot lighter.
I finally feel like she is actually safe in the car. Lastly, getting her in and out of the seat is alot easier also.
ProsSmall size Very sturdy Seems safer than normal
ConsHEAVY Not a breeze to install

September 8, 2019
I've had the Diono R100 and loved it before but they don't make them anymore. I went with the upgraded replacement which is the RXT and it is the same frame plus added side head support. It is also still narrow enough to fit 3 side-by-side which I need! I bought 3 of the same and the 3 kids are comfortable and the youngest is still rear-facing in the same seat, but we'll remove the base when we turn her around and will have 3 identical seats, all sturdy and comfy!

Love this carseat. When it came time to replace/purchase an additional car seat for our family this is the only brand we would consider. They are really heavy, but so easy to install and slim fitting to allow maximum positioning within the car.
ProsEasy to install, sturdy
ConsWeighs a lot but quality and ease of installation make up for it.
Best UsesNeeded something that would work for my older (6) older, petite daughter and also work for our toddler. This was a perfect harness seat to allow us to keep our older child in a harness and yet still work well for our 2 year old too.

April 26, 2019
I work in car safety research so besides a safe car I am always on the lookout for the safest car seat. This seat has really great reviews from people as well as the industry. We do not have the biggest car so this seat is great if you need to fit three across or if you need to keep two seats side by side so that one more adult can fit in the back. My son looks comfortable in the seat as well. Albee Baby has the best price on this seat and the rewards program is the best. Highly recommend!

Our friends had recommended trying these so we could get three car seats across in a small car. These fit perfectly and it‚€™s pretty easy for our almost 3 year old twins to get in and out of. Plus, the product was cheaper here compare to competitors. Would definitely recommend, especially if you are looking for car seats for a more compact car!

March 15, 2019
This is a very versatile, very comfortable car seat. Our 4 year old still uses his and we bought another for our 7 month old because he's growing out of his smaller seat. The removable infant cushions are a great fit for him. Straps are comfortable with a very soft padded cover on the harness. The only downside is that it is quite heavy to carry, but we only do that when we travel by air. The heavy steel frame does mean great safety, though. Highly recommend!

Three across, Best for the Money
March 2, 2019
We drive a Ford Focus which is, in my opinion, only a medium sized car. The choice was between buying a new car or two Dionos when we had our third child because there was NO WAY we were getting a third seat in with our daughters previous booster. Although Dionos may be one of the more expensive car seats out there, they certainly are cheaper than a new car! We still are able to use our original infant carrier with the two dionos but I like these so much I will likely be purchasing a third eventually. They‚€™re solidly made and have the most room to grow I‚€™ve found, especially for rear-facing, and I‚€™ve done a lot of research. I like the side impact head rests as most children are killed or injured in side impacts, and also they make sleeping easier for the child as their head won‚€™t rock forward as easily. Best bang for your buck and cheaper than Amazon even on this site!!
ProsNarrow and large age range, able to rear face for very long. Fits three across, best quality you can buy
ConsHeavy, top heavy/tips over (when free standing), some people with larger hands may have more difficulty with the install
Best UsesFamilies with more than two children (or are planning on more than two eventually) or anyone who cares about buying the best safety for their child due to the high quality and rear-facing abilities.

I never used these for rear-facing, but for forward facing they lasted quite a while even for my tall boys. We kept these in Grandma's car so they were not used daily, but they were easy for my boys to Buckle in and out and I felt they were very safe in these. Plus the colors are great!

Slim Carseat, Just What We Wanted
January 14, 2019
After much research, we ordered the Diono Radian RXT wanting a safe convertible seat to last and also narrow enough to install next to another carseat. This is it! It's taken a little getting used to, but now a week in of using it, we really like the ease of the harness and my son has never once cried out in discomfort.
Pros-narrow size -decent price based on reviews -safety ratings -adaptable install methods -drink holder included
Cons-It took us a while to figure out installation

A year later we still use this carseat, we've never had any issues and its in great condition besides a few goldfish crumbs. My daughter loves it and can climb inane out on her own. She rides rear-facing and its the only carseat that fits 3 across rear-facing in my car. Now that her twins brothers are outgrowing their infant carseats we will be purchasing the same seats for them! Diono is great!

I am praying that we can get our other seats to work.
December 10, 2018
We're trying to fit 3-across in a sedan, and of course, that's a nightmare regardless of what seats you have. We got this one because it's so narrow, and would likely make a 3-across setup easier to achieve. But OH MY GOSH, I hate this thing so bad. It weighs 3 times more than our other car seats, it is way less intuitive to use, and honestly if there's any way whatsoever to get our other Graco seats to work in our Honda Civic, I'm sending this behemoth back immediately.

This thing was probably designed by NASA. Sturdy and compact? Check and check! Could probably keep your kid safe in the Challenger explosion! Short of needing to travel outside earth's atmosphere, I can't see why this seat would be anyone's first choice, because I definitely feel like I need to be an astronaut to make adjustments to this seat.

We already had a Diono RXT and got another one on sale for the other car. It keeps my daughter comfortable and safe. Also like that it has the steel frame and is slightly narrower so other people can still sit in the backseat.

This was recommended by my sister and has been the best seat for my son. He is rear facing and loves being comforted by all of the padding
It's beyond easy to get in in and out everyday.
Easy to install and remove if needed, as well easy to remove the fabric to wash!
I love that it is slim and doesn't take up much room and will definitely purchase another convertible seat for my next child!
Thanks diono!

We were having issues getting all three of our kids in the back safely in their car seats and booster.

All the kiddos are much happier now and I don't have any worries about their safety anymore.

They are easy to install, narrow across the seat, and my daughter is very comfortable in it. I also very much love the safety features and that the frame is made of steal. This car seat was recommended to me by a fireman so I knew it must be the best. I should also mention that both my daughters are very comfortable in this car seat.

Diono FTW!
September 5, 2018
We got the Diono Radian RXT and love it! We've had Graco, Chicco and Britax for our older kids, and we're really liking the Diono car seat. It is very heavy, so it's not easy to move from one car to another, but that's something we don't encounter on a daily-basis. Overall, I highly recommend this car seat!
