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.
Pros
  • fits 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
Cons
  • nothing I've noticed

My daughter loves her diono car seat. We go on lots of road trips and she says it’s a comfortable ride. Also slim and makes sitting in the back with you comfy too. From what I’ve researched it’s a very safe car seat! We have 3 diono car seats and I recommend them to everyone!

We love this car seat so much. My only complaints are that it is extremely heavy and it’s not very easy to clean. But, it’s a car seat and does not leave my car very much. We have 3 of these and will likely purchase another as we are expecting baby #4.

Great for putting multiple children in a row
October 14, 2020
We searched and read so many things about car seats. We are happy with the Diono Radian RXT and Albee baby had the best price we could find. We ordered two one for each car. The reason we went with the Diono was because of their safety rating and that it was versatile. We have a tendency to have small babies in our family and they outgrow because of height more than weight. The Diono offers us confidence that if in a wreck the babies will be safe. I would recommend checking out the videos on how to put the carseat in the car and also considering the wedge if your child is going to be rear facing. We bought the wedge and it was totally worth it for us. Now she is older, almost 3, we have turned it around and she never complains about the seat and has no problems on long drives. I would recommend it for sure. Wish I could give it more stars. We LOVE it.
Pros
  • Safety, comfortable, doesn't take up much room, easy to use buckles, 3 way harness, can attach different ways depending on the car, good quality.
Cons
  • you need to read the instructions or watch the video to make sure you have it installed properly, Think the wedge is needed if you are using in the rear facing mode

December 2, 2019
This love this car seat so much that when we had another child we bought another two for multiple cars! It is heavy, but I love that it has a steel frame which to me means safety! Super safe but also a slimmer design so you can put 3 across which is a plus when you have multiple kids and not a ton of space in the back seat. This is a quality item and so worth it when it comes to keeping your little ones safe and comfortable on road trips! It will last their entire childhood (Car seat/booster years) since it’s rated up tI 120lbs. So for me it was with the investment in getting several of these car seats. Love my Diono!

Good but not great
November 14, 2019
good but not great. Sturdy construction. Quality compares to the higher end Britax seats we’ve had, which is hands above any Graco product (for comparison). Bought this as an all-in-one car seat because it is so adaptable, and we’ve seen many changes in the last 10years of having kids.

Pros:
Very versatile
Customizes to all different sizes of children
Quality is great
All in one, so no more car seat buying
Narrow, so we can usually fit 3 across

Cons:
Installation is not as easy as Britax click-tight car seats. In fact, installation could be difficult in some vehicles
Putting in a middle seat position is still tricky
Very long front-to-back in rear facing position, even though it’s narrow
Can’t fit 3-across when used in conjunction with our Britax (but that’s because the Britax is a monster)
Pros
  • Lasts a really long time, quality build, grows with all stages across childs development, narrow
Best Uses
  • Three across or multiple children in one car
  • Stays in one place and one car after installation
Cons
  • Installation somewhat difficult
  • Car seat is heavy

Great!
September 27, 2019
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.
Pros
  • Easy assembly and install. Looks to be easy to remove cover and clean as well.
Cons
  • Not 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.

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!
Pros
  • Easy to get your child in and out
  • Easy to tighten and loosen straps
  • Slim profile
Cons
  • None

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!

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.
Pros
  • Small size
  • Very sturdy
  • Seems safer than normal
Best Uses
  • For compact spaces
  • For safety
  • For peace of mind
Cons
  • HEAVY
  • Not a breeze to install

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.
Pros
  • Easy to install, sturdy
Best Uses
  • Needed 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.
Cons
  • Weighs a lot but quality and ease of installation make up for it.

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!

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!!
Pros
  • Narrow and large age range, able to rear face for very long. Fits three across, best quality you can buy
Best Uses
  • Families 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.
Cons
  • Heavy, top heavy/tips over (when free standing), some people with larger hands may have more difficulty with the install
