Excellent Car Seat!
We bought 3 of these seats because we traded a vehicle in and got a smaller car. Our previous car seats no longer fit 3 across in the back of the new car so we had to research seats fast to find one that would. These did not disappoint! The material is a nice micro-suede texture. The seats themselves are very heavy but solid. There is plenty of room between the seats in the back of the car now. The bottom area of the seat expands if you have space to do so. I wasn't sure about the color right away from the picture but it is a little more camel color than this light looking beige in the picture. Overall, I love it.
ProsFits 3 in a row, good for small cars, solid structure, good for 10 years

Why did I wait so long?? Could have been our only car seat purchase ever.
The Diono R100 is excellent! This frequently overlooked little brother of the Diono family is really a gem! Bought this for my 5 year old when he wasn't ready for a booster seat after his "forever" car seat expired. This would not have been an issue with the Diono boasting a 10 year lifespan and reinforced steel frame. I wish we'd have started with this car seat. It's trim and fits nearly anywhere, my 40# 5 year old has so much growing room and can easily buckle himself in. We are ready to purchase our second R100 for the 3 year old as she can't seem to keep her chest clip in place in her current car seat. The R100 strap pads keep the chest clip in the optimal position so I have the assurance that my little people won't be injured by improper use if we were in a wreck! The R100 was easy to install with just the seatbelt we were able to get a snug installation. It is hard to move from one spot in the car to another because it's so heavy but I know it's safe in any seat of my 12 passenger van. All in all a great purchase and we will be buying another very soon.

Great seat
This is a wonderful car seat. It's quite heavy so not really the seat for switching back and forth between cars. We purchased it because it's narrow and we're having a third child. We are using it for our three year old who seems to like it very much. And we like it enough that we'll likely get another for our one year old soon. This was also the best price we found plus free shipping

Very Sturdy and Well Built!
We purchased a Honda Pilot 2017 and we have twins. We wanted to place both car seats on the 60 portion of the 40/60 second row seats. We wanted to have easy access to the 3rd row seat by pulling down the 40 portion (seat) with ease. NONE of the car seats that we purchased and tried would work. They would be too big and in the way. We purchased 2 Diono R100 and it finally worked!!! We now have access to the 3rd row without have to uninstall and then install a car seat. The DIONO is VERY heavy, but I think it is well built and very strong. The installation was VERY easy. I looked at some youtube videos and it was a breeze. Once the seats were put in place, it was secure and did not move at all. I knocked one star off, because when the twins fall asleep their heads are bent forward or wobbling everywhere. Diono should add a pillow or make the sides a little more longer (forward) so they can rest their head.
ProsSafety Well built Secure Easy install Space saver
ConsNo pillows or side panels long enough to rest a baby's head while sleeping

Quality carseat/booster
My son loves this seat, as he thinks it's a racecar seat. It sits nice and high, has quality steel construction, and a removeable cover. Will likely buy another for our 2nd car!
ConsI think it's a little hard to sit on, but my 4.5 year old says it's not, so he's the expert!

Definitely fit 3 across
We bought 4 of these. 2 for each car. They are so slim, my daughter actually fits better and has more room than before in our midsized suvs. I didn't think that they would fit well rear facing but they are no bulkier than the infant seats. They are also super soft. I wish my car seat was that soft and comfortable.

Minimal, solid, works great but beware if you own a Subaru
I love the look and feel of it and got it at an unbeatable price. One disapointment for us is it does not work in the middle seat of the 1997 Subaru because of the cars seatbelt design but works well forward facing on the side seats but not rear facing. It didn't work for our one year old but we were able to use it for our 4.5 year old instead.

Great Car Seat
This is my favorite convertible car seat. I love that it will fit my child through the booster stage. The other convertible car seats I have tried are very clunky forward facing so we ended up spending more money with our first two children purchasing more car seats when we could have just bought this.

Overall great! A little heavy
I am very excited to start using this with my son. Set up was easy (he is forward facing with 5 point harness). My only complaint (which I knew when buying it) is how heavy it is. Otherwise, he seems to fit in it great and I love how it fits in the vehicle, giving him more leg room than a traditional convertible carseat. Look forward to not having to buy another carseat in 5 years for my newborn! Albee shipped extremely fast! Will be using this site in the future!

Love Diono seats!
We already had 2 Diono Radian RXTs and ordered the R100 for our 3rd child to fit 3 across in my SUV. The install is super easy, which is always nice. I would highly recommend the angle adjuster to make room for taller passengers/drivers. I love that this will be the last seat that I will need to buy for my daughter!
ProsEasy install Longer expiration than other seats Cleans easily
ConsSometimes hard to get straps tight enough

Buy this! Don't waste your money on anything else.
I've bought many many car seats and wish that I bought this from the start. I would've saved myself money. I drive a Subaru Impreza and this fits perfectly and I still have space for family to sit comfortably next to my son. It is a heavy duty car seat and I will be purchasing another Diono for our little one coming in April.

LOVING this carseat!
I was hesitant to purchase this seat as I hadn't really heard much about this brand until I started looking for a narrow carseat. My only regret is that we didn't buy this years ago. We have 5 children and really needed to find seats that would fit nicely in the car and still allow room for the older children not in carseats to have room. This is the carseat for you! It does not have cup holders but we didn't need them as drinks are not allowed in the car. Originally we had planned on just using this carseat and keeping the bigger Britax in the other car however I am thinking I might just go ahead and buy another one of these as I love it that much. So glad I found it!
ProsSize is fabulous! It is a very sturdy feeling seat so don't think because it is narrow, it is chintzy feeling. I also really like the ease and feel of the hardness.
ConsNo cup holders, but do you really need those? I don't allow eating or drinking in the car so didn't impact us.
Best UsesIf you need space in the back seat to allow room for additional children, this is the carseat for you!

Great quality, easy to get child in and out
This is exactly the car seat I was looking for and it is even better quality than I thought. I needed a car seat that would be easy to get a child in and out without bulky sides or cup holders. Forward facing this is great and is relatively easy to install. It is heavy, but I don't plan on moving it much. The straps are easy to adjust and with the padding they don't slide down when the child is not in it.

Completely Satisfied
I had a hard time convincing my husband to trade in our not-expired-fair-condition car seats for three Diono Radian R100s. I had heard a lot of hype about the awesomeness of Dionos but they were a bit cost-prohibitive for us until we received some unexpected gift money for our sons. Happy to report that we are completely satisfied with our purchase. My husband was actually really excited about the initial few days using them - he was the one bragging to people about our new car seats! Too funny. My 4 year old was constantly complaining about how uncomfortable he was even during short trips in the car, and he has stopped complaining now that he sits in his new seat. Like other reviews, yes, they are heavy, but I had no problems installing them securely in our Town and Country minivan, and we don't have the need to switch seats to another vehicle. For now, we've just got two car seats in the third row because our youngest son is still in an infant bucket seat in the second row; however, I can easily see how three R100s will fit snuggly in the third row once need be. My favorite part of the this seat is the harness. It is extremely well made, easy to clean, and it seems super safe - it's almost like the rider is a jet pilot! We joke with our older sons about strapping into their pilot seats! My expectation is to use these seats for the entire time we actually need them - our three boys are ages 2 months, 2 years, and 4 years - and we're open to God growing our family more, so we'll probably need car seats for the next 8-10 years. I have no doubt that these will wear the years well and safely.

So worth it!
I'm so glad this is on sale because the regular price is way out of the budget. I had a lot of trouble convincing my husband to get it but he's really happy with it now. He does all the installing and can have a lot to say about all my baby gear that isn't made properly, or safe enough for baby - but this item, he was instantly a fan! It's heavy and gets installed just right. We bought the pad that goes underneath for rear facing and it looks great, baby fits great, and parents feel like their family is safe. 5 stars!
ProsStrong, heavy, safe, and durable!
ConsNo infant insert for the price... we bought the diono head support separate and love it though!

Wonderful Carseat!
We love the Diono Radian carseats. We have 2. We need to fit 3 kids across the back seat of our cars and the dimensions of these seats and the overall slimmer design, allow everyone to have the seat and shoulder room necessary in the back seat. The lower sides also make getting "little one" into the middle seat much easier as well! I would buy 10 more of these if I needed them!

I knew the carseats would be great as I researched them... they have not disappointed me!! I bought 5 of these for my new van. These are for my small inhome daycare that I have. I knew these would work for all ages of children that I have. They also work perfectly 3 across in the back seat and when need will do 3 Diono and an infant seat. When ever I need a baby or child product, Albee Baby is the first place I look and also the place I recommend to my families and friends.

Love diono
This is our second Diono seat. We also have the RXT, which we use for our 2 year old. Our 4 year old uses this seat. I debated getting another RXT but decided we didn't need the head wings. That was definitely the right decision, the four year old prefers the extra head room and it's easier for him to look out windows etc. The Dionos are super heavy-- but, I'm six months pregnant and can install and uninstall it without issue. It's much easier to install than our graco seats. These are built to last, easy to wash and overall a very good investment.

Our Favorite seat
While extremely heavy, the Diono Radian R100 is a great seat. Comfortable, easily adjustable, has all the attachments for seating arrangements you could need. I love that the instruction manual is tied to the unit, so it safely stays behind the seat while it's in use. Fabric: we have owned both the red and this khaki seat. The red fabric may have not been as comfortable as the khaki, which is more like perforated leather. My 4 year old calls it bandaid fabric, which is close to the way it feels, like a padded waterproof bandaid. The crotch buckle is a bit tough to press enough to open, my 4 year old has a hard time with it and has to be let out of her seat still. We have found when you need to move the seat, wearing it like a backpack has been helpful in carrying it. It's preferable to our Chico Next Fit, which is not only heavy, but an awkward shape as well. The Diono R100 is a very slimline seat. We fit 2 in the back of my '08 Honda Odyssey Touring with room for another child in the middle. The height and weight limits are great. My 7.5 year old just transitioned out of the 5 point harness on her Diono when she reached a height that we were comfortable with using a regular seatbelt with.
ProsSlimline Comfortable Relatively easy install Wide range of child fits High weight and height limits

Love our seats!
We decided we needed to get a couple of smaller car seats because I do daycare and will have 6 kids all in car seats. We decided to purchase the Diono and we couldn't be happier! We have one of our sons rear facing still and our only complaint is that the driver seat can't go back very far in our odyssey but we are still able to make it work! My other son is front facing and he loves his new seat! The color is the picture is off and once they got here I liked them WAY more! We are still talking about buying a couple more of these for our other vehicle!
ProsFits 3 car seats on one bench
ConsWhen rear facing driver or passenger seat can't go back very far.

Awesome product and service
This brand makes the best car seats in my opinion. It will grow with your child, my child is 41 inches and 42 lbs and sits comfortably in that chair and have a lot of room to grow into. I had a chicco next fit, man was that a bad purchase, it lasted us less than 1 year and was already too small for your kid. The Diono is really well built and comfortable, seat is very breathable hence very comfortable for the kid. It's also very slim unlike the bulky design of chicco nextfit.
ProsThe best part about this is that this is the best car seat I can find and Albeebaby had the best prices (by far) and the delivery was super fast considering the distance.
Best UsesFits great in the back seat and does not take a lot of unnecessary space. Good fro traveling since it folds nicely and also makes changing from one car to another easy.
