My daughter is tall for her age. This car seat offers plenty of space and it doesn't look and feel so bulky.

My kids love this car seat! So comfy, easy to clean and the kids don't complain! I can know fit in a third car seat in the same row! The only downfall for me is how heavy they are but I understand why they are. Totally recommend this car seat to everyone!

Much better car seat!
May 19, 2017
We had a different model before and found that after using these life got a tiny bit easier. Installation was pretty straight forward and buckling is much easier! The best part is that we can fit three next to each other so it saves us having to commit to buying a new car!

Excellent Car Seat
May 19, 2017
We have used Diono car seats for over a year now and we love them. Especially great if you travel a lot and need to bring a car seat on the flight. Easy to travel with. We decided to upgrade our Diono to the Radian RXT. Very happy with is so far. We like having the headrest for our now 2 yo son. Previously we had the Diono Radian 100 and we love that one too.

Improved Diono Radian RXT
May 17, 2017
Love this car seat! We love how slim this car seat is. It allows you have 3 car seats or a mixture of 3 car seats/people in a row. It's very easy to put you child in and tighten straps. I like that they added a thin pad around the pelvic area buckle. It makes it more comfortable when child is in shorts or a dress so the buckle strap does not dig into the skin. This is an upgrade within the last year.

Love this car seat. Just transitioned my 9-month-old from her infant carrier & I'm really pleased with this car seat! Love that it will grow with her until she no longer needs a car seat/booster seat. Well worth the money & I had so many recommendations for this product!

Excellent purchase!
April 30, 2017
I just recieved two of these for my 2013 Nissan Murano. Previously had two Britax Marathons. One is rear facing, the other forward facing. We love the extra room they provide in the back seat wirh them being so narrow and the cup holders. Also love that our kiddos can see eachother face to face in them! First use and they both knocked out comfortably! We love them!
Best UsesNarrow, great for travel, longevity (growth of child)

Perfect Fit
April 15, 2017
We purchased this carseat in order to fit three carseats across the backseat of our van. This is the only carseat that would allow for this that would fit the size and ages of the three children who would be using them. Albee Baby offered a %20 off promo which saved us $60.00!! This was the best price on top of free shipping that we could find after months of shopping around. The seat itself is amazing and holds true to all the reviews and the product discriptions.
ProsVery narrow and the seat folds flat when not needed for easy storage
Consit is very heavy... but that adds to its safety for child so worth it!
Best UsesThis is truly the only carseat you will ever need for your child from 5-120lbs!

So far so great!

I've only had the car seat for about a month now but I think it's great. Easy installation, very roomy for my tall 18 month old, pretty heavy but worth it. Compared to other seats it's a excellent price because it converts to a booster.
ProsInstallation, converts to booster
By Tiffany Briggeman
Love this carseat!!!

This is hands down the best carseat I have ever used.

3 Across the Back
March 27, 2017
This is the third Diono we have bought. We just switched our third from his pumpkin seat to this and it fits very well rear facing (with the adjuster- sold separately). When front facing, this seat is prefect, when backward facing, it is very hard to tighten the shoulder straps. I can't figure out why but the strap is nearly impossible to pull no matter what angle you attempt. This is not the only seat with this problem, though. Almost all of the ones I have used have the same problem.
ProsSuper solid feel. I'm confident it is a dosage seat. Narrow to fit three in the back seat. This is the only see I can do this with.
ConsVery hard to tighten the shoulder straps when backward facing.
Best UsesInfant who can sit up on his/her own and older.

I had to buy all 3 new car seats so that they fit in your Chevy equinox. Thanks goodness they all fit together. Nicely made, colors are rich. Only issue is my son did say they were hard, but they have memory seat cushion so who knows.
By Sara
I wish I would have purchased this first!
March 19, 2017
I recently purchased two of these seats because we are having our third child and there was no way we could fit another seat in our car. The box was smaller than any car seat box I've ever seen (as it comes folded), and I was pleased to see how narrow it was. I hesitated at buying these seats when my other two were due for new seats, but instead purchased two different Britax seats--great seats but definitely too wide to fit a third. I would suggest if you plan on having three kids or more save the trouble and buy this seat up front.
ProsNarrow Folds flat for travel
ConsHeavy Not compatible with inflatable seatbelt position--I wish I would have seen this before purchasing, but we shuffled seating arrangements (but not all passengers are happy with current placement)
Best UsesThree car seats in a bench row; low height makes it easy for children to climb in and out
By Celia
The best carseat!!!
March 18, 2017
This is a great carseat!! It's narrow enough to fit 3 across without compromising comfort. You can tell it is very well made. This color is nearly impossible to find elsewhere and it's beautiful.

Nice compact car seat
March 17, 2017
I love this seat. It's versatile and saves so much space. I had a chicco next fit for my toddler. He kept complaining that he was uncomfortable. He's very happy now.
ProsSturdy, folds up for travel, takes up less space, comfortable,SAFE

Great seat!
March 15, 2017
We decided on this seat after looking at several options. It fits great, as we have 3 across, and I feel confident in its safety, as we drive hours daily. Definitely would buy this again if we needed another.
ProsRemovable cover for washing. Easy to secure. Extended rear facing. Narrow.
ConsHeavy. A lot more adjustments to getting it fitted properly.
Best UsesFitting 3 across, extended rear facing

Diono Radian RXT
March 2, 2017
Our vehicle was totaled in a recent accident and we had to replace our car seat and we knew we wanted another Diono Radian RXT, so we searched the internet to find the best price and Albee Baby was the best price available. Saved a lot of money and easy process and received the car seat in about a week. Our son is very happy with his race car colored car seat and we are happy with the 10 year life span so we can get a full 10 years use out of it since we have a baby on the way. I would purchase from them again and recommend others.

Fit 3 across in my Toyota!
March 1, 2017
Happy with the carseats. They have a nice narrow fit in my Toyota highlander making it possible to get all 3 kids in the back row. They are a little difficult to get securely installed at first, (keep in mind I'm putting 3 in right next to each other though!) but after getting them in there tight it's a good fit. Kids love them:)

Diono Radian RXT
March 1, 2017
Love the Diono brand car seats. I feel like my children are so safe in this brand. My daughter is turning 1 next month and the infant car seat was getting to small for her. But really the cheap plastic of the infant car seat just made me want to get a convertible car seat for safety issues. My older daughter has had her Diono for 3 years now and it is so easy to clean and install. Love it!
By S
Fits well with "angle adjuster"
February 26, 2017
The foam angle adjuster makes all the difference. The front seats were not accessible with the car seat until I used the angle adjuster. With it, the seats fit nicely and fit in the driver's seat in a PriusV. Love that these are narrow. Install isn't that challenging if you read instructions first and use common sense. Currently have one on each side, but will try them next to each other to allow access to a seat in the back. Love that they work for a long time for rear facing (height and weight).
ProsLasts long time, longer rear facing, narrow, low profile
ConsNeeds angle adjuster to make it work
Best UsesExtended rear facing, 3 across

Quite Comfortable for my little guy...
February 24, 2017
This seat is big! I have a minivan and it didn't really fit too well into it. It took up so much room that only I could drive the car with it installed, my husband didn't have enough leg room. So, we had to order the pad to go under the seat and then it gave us a few more inches so my husband could fit comfortably. My son is super comfortable in this chair, he was hating the infant car seat. Overall I am happy with the purchase and picked it for the excellent safety features and ratings. It will be even better when it is forward facing.
ConsTake up a lot of space rear-facing.

Best fit for growing family
February 15, 2017
I wish I'd bought this with #3, instead of waiting until we had four kids in the car!!! This is the best seat to fit side-by-side, and I'm so glad the rear-facing lasts for so long! The instructions are also very thorough and go through everything you need to know about setting up the car seat. It is a very heavy, very durable seat and the only one I've seen that lasts for 10 years.
Best Uses3+ kids, side-by-side, extended rear-facing, large families
