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

Love it!
We purchased this car seat specifically for its stellar safety reviews as well as its narrow build! We shopped around and were very happy with Albee Baby's pricing! The only feedback my husband (the car seat installer had) was how heavy it is. But, as it will simply be in one car the weight of the seat isn't a deal breaker for us! Make sure you also purchase the Diono Angle Adjuster as it does make a huge difference in space as my daughter is still rear facing!

These seats are very narrow which is great. We have two side by side now in my GL450. They are SUPER HEAVY though. So if you are looking for something to take in and out of your car a lot this may not be the seat for you.
ProsNarrow, Straps are easily adjusted
Best UsesVehicles were you will not be moving them in and out a lot

Safe car seat
This is our 6th diono for our 3rd baby. All three of our kids love these seats, I love that they fit three in a row in my suv and my husband's truck. This version is much nicer than our 6 year Olds they have definitely made much needed improvements.

Love Diono and love this color!
This is our fourth Diono seat. We buy them because of their incredible safety features and ratings and also because we have four kids in car seats so we need to maximize our space and these seats are perfect for that. This is our first “cobalt blue†seat and I absolutely love the color.
ProsSize, safety, color
Best UsesIf you need to fit 3 car seats in one row, you need Diono seats!

Safest by far
Purchased for the Grands X2 and with the reviews and seeing the inner safety features has to make this one of if not the safest protective child devices for transportation today. After looking at the amount of plastic which goes into others this one left me no choice but to do what I could to protect my Grands. Price is always what we look at and Albee by far had the lowest price from the many others searched online for the identical product and getting them in 2 days really surprised me.
ProsManufactured with metal and not all plastic. And removal of the cover for washing after grubby dirty hands with various foods to behold will be all over them for sure. Will have to see about durability. Fits 3 in the vehicle if needed.
ConsNot quite sure of any at this time. Daughter loves them for her babies.
Best UsesAs previously stated having he dimensions to fit 3 safely will come in handy for #3 which comes later.

Great car seats
We have had the car seat for about two weeks. So far we really love it We picked this car seat because its safety reviews and its slimness. We're able to put it in the middle seat next to the infant car seat in our Ford Flex and still able to pull down the empty seat to access the third row.
ProsWell made, only 17" at it's widest so it easily fits in the middle seat.
ConsDoesn't come with cup holder, infant insert or angle adjuster. All have to be purchased separately.

Pleased With Carseat
So far, so good! We have two other older car seats that are Diono brand, but this one is a little easier to buckle, so that is a plus. Hopefully it will work well for several years.

Super sleek and sturdy.
This car seat makes our old ones look like junk. it has a solid frame but is very narrow for the three across option we needed. Material is really nice. Only drawback is the booster cushion that sits on top of the seat makes the bottom buckle very short/close to the legs. We also took our first 4 hour car trip over the weekend and the kids said their bottoms hurt, but hey, so did mine!

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
Best UsesTo save space

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.
