Great seat if you need to fit three car seats in one row
I have a four year old and twin 1 year olds. I originally bought two rear facing only seats for my twins (had to do some research to find three that would all fit in my car). Now that I moved my twins to forward facing I had to purchase another two seats for them that would fit along with the booster I have for my four year old. These seats are narrow enough to easily fit three across either forward facing OR rear facing. I have one fairy wide booster seat + two Radians and while its a bit tight, it easily works. I've also moved all three to different cars and it fit all of them without issues. If I had three Radians it would be even be easier (since my booster is a few inches wider than these seats). My kids like the seats, seem comfortable to them, and are easy to buckle them in with. I didn't try rear facing with the kids in them, but I put them in the car just to see and space was ok that was too. I currently have 10 car seats including my two Radians, and these are one of the easiest ones to install of the bunch. If you are looking to fit three kids in a standard car (I have a Tucson and an Altima), I would recommend going with these. My only regret is that I didnt purchase these originally instead of buying separate infant carriers.
Prosfits three across in a standard size vehicle (Camry, Fusion, Altima, etc). Rear facing OR front facing. Easy to install Easy to buckle children in Seems comfortable
Consnothing I've noticed

Not as great as I thought it would be.
It was much more complicated to install than I thought. I was previously using a Chicco NextFit seat and loved it! I have used Chicco for every seat for all 3 of my kids. Primary reason for choosing this seat is the option to only have one seat that transitions with my child until just a booster seat is needed. I was also drawn to the narrow width of the seat to try and fit 3 across in my Explorer. I feel like I have a really hard time tightening the harness straps tight enough on my 2 year old. Even when removing the padding around the chest clip, I feel like I am still not getting just the right tightness and it takes me multiple times of trying to tighten and adjusting to feel somewhat ok with it. Overall I like the look of the seat and all of the options for transitioning with the seat, but I truthfully don't think I would purchase again and would likely purchase a Chicco MyFit instead.
ProsSuper narrow frame. Ability to transition for all stages of belting needs. Feels like a sturdy seat.
ConsComplicated to install. Heavy. Protective, adjustable head wings are a little tricky to adjust. Harness straps are tough to tighten to preferred position.

Love the ease of using this carseat
I purchased one for my daughter and then had to use it for my grandchild. With bad hands I was still able to easily put her in and take her out. I liked it so much I purchased another one. This way I had my own instead of using another brand that I had a hard time using.
ProsJust the perfect size. Ease of use.

Great car seat, great price
We already own two dionos and this one is the same great seat, but with a slimmer and improved chest clip. It also came with a wedge piece to solve the forward facing 65+ pound issue. We can fit three of these in the third row of our Chevy traverse, with the center seat backward and the outside two front facing.

Best car seat ever
This seat fits perfectly in a Toyota Camry even without the angle adjuster pad. I love that it's FAA approved and can't wait to use it for that. It is a bit heavy but is still comparable to other car seat weights. I love that it can fold and be as a backpack. My child fits comfortably and is happy sitting in a seat finally. Definitely buy for traveling and limited space use.
ProsNarrow Great discounted price FAA approved Manual was very specific, helpful, and easy to read
ConsDidn't want the red color but it was the cheapest Seat cup was difficult to put it

Sturdy, durable and all purpose! Comes with extra baby and booster cushions for when my babies are little. I love that this is the only car seat I’ll ever need! Love the side head supports too! We own 7 of these in total (among grandparents and both parents).
ConsWe found it difficult to install backward facing but once installed, it is absolutely wonderful!

My 4th Diono purchase!
This is my 4th Diono RXT purchase. These are well made, heavy seats. I have purchased 4 total for my own car for two kiddos and grandparents cars. While more expensive than some other car seats they are worth every penny. I prefer the RXT due to the upper wings on the top. This lets them rest their heads when napping while running errands. My son was able to climb up into the seat early on due to the low sides that can be adjusted up or down. The two seats easily fit into the seats of my Acura tsx and now my Toyota highlander.
ProsHighest safety ratings Hold up well over time Comfortable Variety of colors
ConsHeavy for traveling

Would recommend!
We're one week into using the Diono Radian RXT and so far we love it. The installation was straightforward and the angle adjuster allowed us more room front to back. We really love the low profile sides for putting our baby into the seat easily and the narrow width for our small car and retaining use of our backseat. The seat itself is comfy with memory foam under the baby and padding along the straps. The ratchet takes some patience to tighten the harness, especially rearfacing, but we love how snug we can get it and know our baby is secure. All this and the excellent safety ratings made this a great choice for us!

Love it!
With a more compact SUV, I wanted to maximize space while keeping my little guy as safe as possible. This seat does that. I have struggled with using the foam enhancer but at the moment, it isn't an issue. We will be getting another one for my husband's car now that we know we like it so much.

This car seat is rugged and versatile. This is the third one I have purchased. One for each car. Plus one for the baby sitters car. With it's steel frame it is narrower than the all plastic seats i have seen. It actually fits in the airplane seats that I have put it in. Replaceable seat covers and many other parts allow you to change a dirty cover and be back in use in a few minutes then wash the dirty cover when you have time to. The 10 year working life is fantastic.
ProsStrong, suitable for airplane use, long working life, it's not all plastic.
Consheavier than most, but worth the weight. The cup holder detach to easy. My daughter is a thrower.
Best UsesFrom the time they outgrow the infant carrier. Until they are able to use the car's seat with out any added seat or booster. works for flying as well. keeps the child in the seat seated not climbing out of the lap belt and all over the plane seats.

Great seat
Great seat, great site to order! Wish someone told me how far it reclines back in backward facing mode bc definitely need the $10 wedge sold separately if anyone plans on using the seat it's behind & I'm a 5'4" woman in a suburban. Also need to order a second cup holder-only comes with one. For as pricy as these seats are wish at least had 2. Otherwise completely happy.
ConsRecline position in rear facing One cup holder

First and foremost let me start by saying Albee Baby is a godsend! I have 3 boys and have been eyeing Diono since before my second was born 2 years ago, and I am now FINALLY a proud owner of two! Both were purchased just a week ago and I couldn’t be more happier, and am still just as ecstatic. As my 2 year old sits face-forward comfortably and securely, my almost 6 month old lounges rear-facing ultra comfortably and securely just the same. Months of thorough research and I never came across a price for a BRAND NEW Diono Radian RXT as I found at Albee Baby. As they say, “Good things come to those who waitâ€. :)
Pros- beautiful design and vibrant color - very soft high quality fabric - memory foam cushioned - very well padded chest straps like no other - cup holder that can be placed in 4 different places - easy latch - high seat back - slim seating yet very roomy with seat width extension option - though quite heavy than most the weight only confirms its provided safety
Best UsesTruly for anyone with more than one child.

love the sleek design
I have a maxi cosi pria85 and although I love it, it's too bulky to fit more carseats so for my older daughter we got this one and we were impressed. It was recommend to us by a friend who has 2 year old twins and a 3 year old son so even though I'm usually worried about ordering something I couldn't physically see or touch, I'm glad I took the chance!
ProsSpace Saving, cool design, comes with a cup holder
Consvery heavy!
Best Useswhen you have several young kiddos close in age and need more than 2 carseats in the backseat.

Very Satisfied
I ordered two of these seats with the intention of ordering another probably in the next six months. Baby number three is almost ready to arrive and these seats will fit three across in my Jeep Cherokee. I love the seat for my three year old as I have set it forward facing. However, I have another little one that's not yet two and is still rear facing. I find it really difficult to get the harness adjusted tight enough on her. The strap release is awesome when loosening the children, but this same positive makes it difficult to pull the harness tight when rear facing.

Worth the investment
I had a previous child and plenty of experience with different styles of car seats. This one fits the bill for many of my previous challenges. 1. If I had 2 children side by side with any type of a seat -infant/booster/convertible it was next to impossible to put 3 children side by side. I'd have to squeeze a 3rd person between the two and it was not pretty. Now it is much easier to put them side by side, as well as someone in the middle. Huge difference. 2. As my first child grew, the higher arm rails became problematic because they were so high it was difficult to get in and out of the car and then into the seat. Plus because the arm rails came around both sides there was not a lot of wiggle room as he grew, which made sitting in it feel "tight." Being able to have the lower sides is invaluable both with my newest addition in getting her in and out of the seat because it is less of a bucket style, and for her as she gets older as well. 3. My second gets to be lugged around town quite a bit, and I had no idea how uncomfortable most car seats are, these seats have a memory foam cushion, not just a thin strip of fabric on top of plastic. I cannot imagine traveling on plastic all day long!?! How uncomfortable. 4. It's so easy to take in and out of the car. Yes it's tall, but it's easy to clip in, tighten and done. Just like a base for an infant car seat. 5. I rest assured knowing my child has more than just plastic protecting her :)

Delivers wonderfuly
I have used many seats over the years and I must say this is truly an amazing seat. It fits wonderfuly in my Honda Fit. So many times parents with compact cars struggle to get a seat that fits the child confortably yet doesnt push the passenger side front seat into the dash. This seat fits right. The straps are padded so wonderfuly and are the removable padding makes for easy clean up. This seat is worth every penny for style, fit, and safety.
ProsFits in compact cars easily.
Best UsesCompact vehicles or where space is limited.

Another Great Buy from Albee
I purchased two of these car seats for my 8 month old twins in anticipation of their growing out of the infant seats soon. I already own one for my 3 year old. We require a car seat that will fit three across in our vehicle and this is one of the few out there. It is very heavy and we did have a learning curve (with our first seat) in getting it installed properly, but now it seems to be all good. We have yet to install these, as I'm going to milk the infant seat as long as possible (so convenient). I'm hopeful these will be the last car seats we'll need to buy as they can be used as a booster up to 120 lbs and are good for 10 years from the manufacture date. As usual, Allbee had the best price (Black Friday deal), free shipping, and no tax so it was by far the best deal out there - shipping was fast and it all arrived as ordered within a week.
ProsFits 3 across Can be used up to 120 lbs Ten year life

Excellent comfort and protection for our twins
The seats we purchased were excellent and stayed that way as our daughters grew. Unfortunately due to an accident, we were forced to discard the seats. At this time, although we want to have replacements, we just cannot afford to lay out $800+ to purchase new ones.

awesome car seat
This is an awesome car seat. It's easy to get on off the car and can be folded for travel/storage. The best features in my opinion is that 1. it has small foot print so so you literraly fit 3 Diono car seats in a regular sedan (camry). 2. even though it seems less bulky but it does not lack in comfort. 3. Solid build quality with steel/medal backbone.

Perfect for my child who is at the 100% for height & weight!
After installing the seat I complained that the straps should be longer. 'why don't they offer longer straps" I said. Guess what THEY DO!!!!!!!!!!!!!!!! Thank you Diono

Diono always works!
We needed 3 across for our vehicles so of course Diono was the top of the list for seats that easily fit next to each other! They installed flawlessly, are super heavy and well made, they just never disappoint.
ProsSteel reinforced, comfortable, long lasting expiration, narrow, puzzles well next to other seats.
ConsForward facing belt path/install is tricky. Top tether buckle is in an awkward spot behind the seat.

I got this as part if a sale at baby cotton bottoms. I've done extensive research on this seat since my son was born and I finally took the plunge after 18months. I regret not doing it sooner. I wished I could've gotten another one but as I save up I'm hoping to get another. I love the steel frame and I have a high suv and I'm a short mom so the construction of the seat makes it so much easier to get my son in and out. I highly recommend it.

This car seat makes every other car seat look and feel flimsy. It's so solid and secure, I have absolutely no complaints. I am a first-time mom and a medical professional, and there is absolutely no way I would ever let my child ride in any other car seat.

So Close to perfect.
I have two of these seats, I have loved these seats. They are MASSIVE, and HEAVY, but narrow enough to fit three across. Unfortunately, some of the faults are critical. -The tightening buckle is on the seat side of the tether, instead of the clip side. -The equalization straps/triangle is up too high to work with truck anchors. -I need to sell the seats because they do not work with my new vehicle. Fault of Diono? or fault of ford? Quite irrelevant, Either way, the Best car seat on the market, is not designed to fit or work, with the most Common truck on the marked? I will be visiting our local diono dealer today, to inquire, But our local seat installation specialists, concur, If you own a truck with the anchors under the head rests, as nylon loops, YOU WILL NOT be able to use this seat. To everyone else, Best seat ever. (mostly fords fault) but still to not work with a major manufacturer is a HUGE fault) Even If I could tighten the seats, sharing that center anchor is not viable.

Quality that saves lives
I love my Diono Radian RXT. We were in a car accident, where we double-rolled into a ditch. Myself and my two boys, age 4 & 6, walked away with no injuries. The EMT said they were shocked and said the car seats helped save my boys from injury. I have 4, a pair in each car, and will be purchasing again for our newest child. I never questioned paying the price when it came to their safety, and after the accident, it was the best purchase. I wouldn't trust their life to another seat.

Best carseat for my kids
I bought the first one when my oldest grew out of her infant rear-facing car seat. Fell in love with the Diono and when I had to order another carseat for our second daughter I immediately knew this was the one for us. Only 2 complaints is that they discontinued the "Dayton" red design and the strap between the child's legs is quite short so it is a bit difficult to buckle child when they are about 30+ pounds.
