These are great. They have a slim profile and can be folded and worn as a backpack (with straps sold separately). This will make it easy to fly, use on the plane, and use in the car when we get to our destination.

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 thereā€™s room for an almost 13 year old too. These seats are easy to install, once you find the hidden book. Itā€™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!

We have three kids and their seats didnā€™t fit the way I liked so we switched to these and itā€™s great! I have a Dodge Journey and have two rear facing (ages 14 months and 2.5 yrs) and my FF (5 yrs) in a 5 point harness. I love everything about them!

Overall a good carseat
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.
  • Rear facing up to 50lbs.
  • Easy install
  • Can use with newborn if you buy the xrt model
  • Big and bulky

Best carseat ever!
December 14, 2020
This car seat is amazing!! We own 4 (2 in each car) and we bought 4 for the grandmas! Weā€™ve tried tons of car seats and this is our all time favorite. Itā€™s easy to get in and out, easy to buckle and unbuckle. The straps donā€™t get tangled, and itā€™s heavy duty so it doesnā€™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.
  • Narrow, Easy to Clean, Easy to Adjust, you can easily fit three across in the back seat of a crossover vehicle
  • Heavy
Best UsesWhen you do not have to move it from car to car. When it can be placed and stay there.

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.

Comfortable and Sturdy
November 10, 2020
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.

Hard to decide on the stars
August 28, 2020
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.
  • Sleek design, perfect fit with our old pria85.
  • Storage block for all the parts and accessories
  • Top on safety rating
  • Excellent customer service
  • Difficult to adjust harness and remove cover

I am so glad I went with this car seat!

It super easy to use, it took maybe 4 minutes? I have two under two and it was simple to install and no fuss when I load up the kids. They enjoy it and it fits great in our small city friendly compact car. Would buy again and have already recommended this brand and STORE to my friends ā¤ļø
We didn't use it yet
July 31, 2020
my daughter loves the colors. I had got this car seat for traveling. It's cool that it folds. I brought the straps to go with it but it's still heavy so I'll have to buy the traveling car seat bag with the wheels.

Great Carseat- some limitations though
July 16, 2020
We liked this. It met the purpose we had- being slimline. However in the forward facing position my children always were found with their heads tipped forward where their airways can't safely be kept open. This was very bothersome for them and for my mom heart! I wish it had a reclining option for forward facing seats. Some vehicles have natural recline in their seats and some don't. I see this being perfect in most cars.

Not Heavy, Built Great
July 16, 2020
We have been looking for car seat specifically so we could do 3 across and these are perfect. I saw many reviews about them being incredibly heavy, but they are only 22 lbs which is less than the other car seats we have owned.

Narrow and solid but complicated
July 16, 2020
I really appreciate a few things about this seat. It is narrow yet roomy inside for comfort, the fabric is nice, the straps tighten easily and it's really, really solid. There are only a handful of seats that can fit three across and this is one of them. That said, it is so complicated compared to other seats! So many rules/settings for different weights, the crotch buckle must be in this slot for this size kid, safety stop must be used for these kids, the base has to be in this setting using this release lever, etc etc. I know itā€™s all because of safety but my concern is that due to the many, many rules that it may be set up incorrectly and therefore LESS safe than a different seat. It is also quite difficult to get tight enough using latch. Competitors have a much better latch systems. Also, it is enormous front to back when rear facing. Now that it's in (use a seat belt) I like it but getting there was a challenge.
  • Solid construction, fits three across, nice fabric.
  • Poor latch system (hard to tighten) and really large front to back.
Best UsesForward facing unless you drive a bus.

Heavy and Tall but Great Space Saver
July 6, 2020
This car seat is heavy, but once we got it installed we haven't moved it, so the weight wasn't a big deal for us. I wouldn't want to be moving it from car to car regularly though. We have twins and a toddler who are all in convertible car seats and our toddler wants to be in the same row as his sisters, so we have 2 of the Diono Radians and a Graco Contender 65 all across the middle row of our Kia Sorento. They fit perfectly. The twins seem to be comfortable in the seats and I love that they can all fit in the same row together. The only downfall of these seats is that they aren't adjustable height and they are very tall. Our twins are still rear-facing and currently to be able to access our 3rd row without taking a car seat out, we have to have our son's front-facing car seat behind the passenger seat, which leaves the twins rear-facing in the middle seat and behind the driver. The rear-facing Radian in the middle is so tall that it makes it almost impossible to reach over the seat into the back row to hand out a snack, find a dropped pacifier, etc. Only a minor annoyance and really only a problem on longer car trips. Overall I love these seats!

By Mikeylikey
Great product. Rear facing disappointment.
July 5, 2020
The seats are incredibly well constructed. I have two other all in one car seats Iā€™m my wifeā€™s truck and they are just plastic behemoths. These are streamlined and compact and surprisingly heavy. They have a variety of mounting options to suit any application.

My only complaint; when in a rear-facing position it is incredibly reclined. So much that my passenger seat has to go all the way forward to keep the metal frame from imprinting the leather headrest. This is inconvenient because they are touted as space savers and my backseat isnā€™t small by any means. But, itā€™s not a minivan (which is what Iā€™m thinking they used to design these).

That being said, forward-facing is great. I bought two and the space in between the seats is enough to fit a piece of luggage. We do a lot of road trips for camping and every gained is worth itā€™s weight in gold. Overall very happy. The rear facing setup has a removable base to cause the recline I might take that off and just use the standard recline function. Between that and the tether, itā€™ll be much safer than being unable to be level due to seat interference.
  • Compact, durable, super comfortable straps and a very easy seatbelt tightener function.
  • Rear facing is incredibly inconvenient with a ridiculous recline angle. Maybe just a tad too heavy, but that?s probably a pro and a con.
Best UsesProbably large vehicles if you do rear-facing. My midsize truck lacks the depth to allow the full recline of the seat in that mode. If your kids are over two or meet the requirements, forward facing is where it?s at.

Challenging Install
June 30, 2020
This car seat has tons of rave reviews, and with number three on the way, it seemed like the logical choice to get some extra space in the back seat of my Subaru Forester. The seat itself is quite solid, and the fit and finish is very niceā€”comparable to the Britax Marathon that my three year old has been using. Unlike the Britax, however, which installs quickly and easily, this seat is tough to install. I installed two, one rear facing and one forward facing, and they are both a challenge.
I used the latch system to install both seats, and it didnā€™t go well. As opposed to the Britax, which has two independent latches that make tightening a breeze, the Diono has the system where both latch connectors are attached to one another, and one is fed through the seatbelt installation portal. Other seats that Iā€™ve used with this method have been a challenge to get tight, and this is no exception. Rear facing was a bit easier to get tight, but was still time-consuming, difficult, frustrating, and tiring. Secondly, the ether strap on the forward facing seat is almost impossible to get snug enough that it restricts the seatā€™s movement. The big issue with the seats is that as you pull the straps tight, they begin to act as though they are fully tightened when they are nowhere close. I was pulling with all my might to tighten the latch strap, only to check it and find that I could easily slide a finger underneath the fabric. I am a strong man, and I had trouble getting these straps tight. This was not the user experience that I expected. Now that they are installed, I am happy with them, but wow, what a pain.
  • Nice fit and finish.
  • Sturdy seat.
  • Nice fabric.
  • Incredibly difficult to install

I am a mother of 9 and a car seat safety technician. I have been using this brand of carseats for 12+ years now! They are great for so many reasons! The biggest being that you can fit 3 across with ease. We have used these seats 3 across in a Chrysler Town & Country, a Ford Focus, Honda Accord, Chevy Suburban, Ford F350, Toyota Tacoma, and Saab 930. These seats are also great for travel in airplanes. The 10 years before expiring is another huge benefit! If you break down the cost over 10 years it is literally pennies a day to keep your child safe! Today I am ordering a 3rd one to replace our seat that will soon be expiring.

June 19, 2020
We have twin girls that are almost 3 and a baby on the way. We needed more space in our backseat. These are slim and perfect for adding a car seat to the mix. The straps cinch down so easy compared to our Safety 1st toddler seats we had before. Can't say enough good things about these seats! Super sturdy and secure. Also like that they fold down for traveling.

Well Constructed and Compact
June 2, 2020
This seat is a completely rarity! It is compact enough to put three seats in a row, but also just large enough to still comfortably fit a growing child! The pink color is adorable too! This seat is extremely easy to latch and the 5-point harness is so easy to click together. I had a different brand convertible seat and the lap button was miserable, so this is an amazing upgrade! The steel frame does make the seat a bit heavier, but to me, thatā€™s my peace of mind. Itā€™s stronger, really comfortable, and adorable. Winning all around!
  • Steel constructed frame; easy latch system (or you can use the seat belt); easier 5-point harness button; comfortable; compact.

Beautiful carseat
May 14, 2020
I really like the way this carseat looks, fabric feels really nice too, i got it for my 2 year old, he looks comfortable in it. It is a heavy car seat, but it stays in the car, so once you buckle it in, it's fine. If you're constantly moving the carseat between vehicles, it's probably not the best choice since its on the heavier side, but other than that, I'm happy with it!
  • Beautiful, comfortable, nice fabric
  • Heavy (if you need to move it often)

My daughter absolutely loves her new carseat/booster seat. She says its very comfortable, she is able to easily buckle herself in and of course loves the pink colors. Well worth the price as its will convert to a booster seat. As a parent I wanted her to be in a harnest strap for as long as I could possibly can , and this carseat does that. Well made , steal frame so its super heavy. I also like all the features that it comes with for example all the straps clip nicely in the back and has a place where it goes when your not using them etc. Overall best carseat/booster chair on the market!

Bought for the fit
March 25, 2020
I am a mom of 5. We recently went from an expedition to an Odyssey. My older 2 children are in booster seats, my next child is in a forward facing harness seat and my younger 2 are rear facing in a Britax marathon and a chicco nextfit. When we got the odyssey our baby was still in his infant car seat and my 2 rearfacers could be side by side allowing a booster rider next to them and easy access to the 3rd row for the other 2. Unfortunately the marathon and nextfit are wide seats and we couldn't get them to sit side by side. So, we bought this seat. It fits perfectly! It seems comfortable. I like the harness pads, although they are super thick. It came set for a large child. It took awhile to figure out how to adjust the crotch strap to the first setting. Everything else was pretty self explanatory. The directions were easy to understand in the instruction manual. Installing the seat wasn't too difficult, but I have more appreciation for Britax's click tight system and chicco's cinch tight system. All in all this is a great seat, especially since it can fit in "tight" spaces. My daughter seems to like it and has plenty of room to grow.
