Heavy and sturdy.
January 5, 2024
This is a very very sturdy product; however, it's so heavy and harden to clean and install than most other car seats I have owned. Lugging this through the airport was a nightmare.
Pros
  • Durable and folds.
Cons
  • Super heavy! Harder to clean and install.

Not “slim” for rear facing
June 2, 2023
Good, solid, slim car seat. We needed a convertible car seat for my husband’s truck now that our 9 month old has outgrown his infant seat. Since this is marketed as a slim compact seat, it seemed like the best one to go with. While it is slim side to side, it’s definitely not compact front to back. To fit in the truck, rear facing, the passenger front seat had to be pushed all the way to the front and leaned slightly forward. This bothered me so much at first, I considered selling it rather than try to ship it back. After reading some other reviews online, there is a foam cushion you can purchase to angle the car seat upright (for an extra $25). We purchased the cushion and it did help the problem some. Overall, for front facing this is a great narrow car seat. For rear facing, if you have a compact car or truck, I’d look for something else. For $200 you think they could throw in a $25 cushion which probably cost a few bucks to make…
I do like the seat, design, and feel; I’m sure I’ll like it more when we can turn it forward.. I just really hated that I bought it specifically because it was marketed as a “slim” seat, but only if you’re forward facing.

Solid, easy to clean, lasts for a long time
April 7, 2022
This is our main seat for our 4 year old. Rear-facing install can be a pain, but is usually do-able. Definitely get the angle adjuster! Forward-facing install is pretty simple and easy. We've had to wash the cover quite a bit and it's held up well overall. It's also a narrow seat, so good when you need to fit several kids.

Worth the Purchase!
March 14, 2022
I love this car seat! We originally had a Graco 4ever seat for our oldest, and switched to this after the birth of our twins. This makes it possible to have 3 kids in the back of our Honda Cr-V, and no one is cramped or uncomfortable. We recently used this car seat on an airplane, and navigating the plane with a toddler and this seat was as easy as that could be haha! Would buy again, and would recommend this to all parents.

This car seat is nice and compact to fit in a smaller vehicle, or if you need to get multiple across a row of seats. Feels safe, sturdy, and easy to clean.
Pros
  • Slim, easy to install, comfortable fit
Best Uses
  • Small vehicles, if you need 2-3 across one row of seats
Cons
  • Instructions were not there for installation or putting together, very heavy

August 6, 2021
I buy a couple of this car seats last year.
At the beginning I was hesitant because I didn't know this site before, but the process to buy and the delivery time was great. The car seats arrive without any issue.
This are perfect for 3 in a row. now I have only 2 of this and one Chicco, I'm planning to upgrade the chicco to one of this soon.
Cons
  • This in particular don't have any support for the head, I may try other version with head support later.

I hate this car seat. Based on the product description it seemed like it would be easy to install, but it was the opposite. When it’s in rear-facing mode it’s so long that I can’t put my front seat back very far. It also just doesn’t seem super safe for younger kids without any sort of padding/protection on each side.

Great seat, not so easy install.
July 8, 2021
It's a great seat, easy to manage getting the baby in and out. However, the initial installation of the seat took forever. My usually handy husband installed other car seats in less than five minutes, this took over an hour. It's just a bit tricky and can be frustrating initially.

Very Wide Front to Back
June 20, 2021
I got this for my husbands jeep and I have a hard time getting comfortable even with the extra lift we bought. Its notoriously heavy and my son doesnt seem to like it as much as our Nuna Rava. I will probably end up getting another Rava.
Pros
  • narrow side to side, child can hang legs over the side
Best Uses
  • if you need more the one car seat in a row
Cons
  • Wide front to back, heavy, my son doesnt seem as comfortable as in my other car seat

Good for short trips around town
June 20, 2021
Love this seat for everyday running around town. We don’t use it for road trips because my three year old needs the headrest when he falls asleep. We bought the 3xrt model and are very happy with that for longer rides.
Pros
  • Slim design. Sleek look.
Best Uses
  • Everyday use
Cons
  • No headrest.

We love our Diono carseat! My husband & son were in an accident driving 70 mph. My 3 year old was in Diono on the side that the window was shattered and door was smashed in. My son walked out of the vehicle completely untouched. This is our third seat purchase (2 for 2 vehicles and 1 for replacement from accident). We won't purchase another brand! The material is very easy to remove for cleaning and replace when finished.

We love these seats. We purchased two to fit in the back of a BMW and there’s room for an almost 13 year old too. These seats are easy to install, once you find the hidden book. It’s inside the fabric shell in a pocket on the backside.
No complaints and I love the high weight/height limits! We will gladly use these for years to come! Shipping was fast and prices were great!

January 16, 2021
I like the car seat you buy it . We had trouble finding a car seat that would work with our Ford airbag seat belts. We looked everywhere to see what would work with our car. I finally called a local baby store and they said this brand would work with the car seat belts. It does take up a little too much room rear facing though but I would still purchase it again.
Pros
  • Rear facing up to 50lbs.
  • Easy install
  • Can use with newborn if you buy the xrt model
Cons
  • Big and bulky
  • Weighs a ton

It’s easy to get in and out, easy to buckle and unbuckle. The straps don’t get tangled, and it’s heavy duty so it doesn’t feel flimsy or wobble around. Highly recommend!!

Solid narrow baby and child seat
November 21, 2020
This seat is made with metal so it is very heavy. It is the most solid seat I have ever seen. Also because it is So much narrower than most seats you can fit three across easily in the back seat of my Nissan Pathfinder. It is very easy to take apart and clean completely, easy to adjust and in my opinion the most practical seat I have ever used. I will keep my kids in it and can until they are ready to be in the regular car seats.
Pros
  • Narrow, Easy to Clean, Easy to Adjust, you can easily fit three across in the back seat of a crossover vehicle
Best Uses
  • When you do not have to move it from car to car. When it can be placed and stay there.
Cons
  • Heavy

Great product as ususal
November 12, 2020
This is our 3rd Diono and the first time for the Diono Radian 3R. We are using it with our 3 year old because she didn't need the infant support from the RX one. So far we are just as pleased with it as our other purchases. Thanks to albee baby for great prices and easy shopping as well. You feel like your children or grandchildren in our case will be very safe with these carseats. However, they are not ones you change or move around all the time. They are too heavy for that. We put them in our cars and just don't move them very often. We make sure to have at least one in each car.

Great carseat. Heavy and sturdy. My son seems to be more comfortable in this seat than in his other as he has more space to spread his legs since the sides do not come up as high. It was also easier to install than our other carseat. I plan to purchase another one for Grandma's car.

Bought this car seat for my 4yo, he seems to like it very much but not so much for me. I have to reinstall the carseat to remove the cover for wash, or to adjust the harness. It's kind of heavy labor considering the heavy steel frame of the carseat.
Pros

  • Storage block for all the parts and accessories
  • Top on safety rating
  • Excellent customer service
Cons
  • Difficult to adjust harness and remove cover
