Very sturdy.
This is a very sturdy seat, the fabric is good my son doesn't seem to get hot sitting in the seat. It is easy to install. The one draw back it you have to remove the seat and reinstall when you need to adjust the height of the harness.
ProsStrong and sturdy
ConsMust uninstall car seat to adjust harness height.

Doesn't fit anywhere near the 57'
Even though it's advertised to accommodate a child up to 57' and/or 65lbs., the upper shoulder strap slots are at 17'. The shoulder straps have to come out at or above the shoulder. This seat won't handle a child over about 45'tall. It was useless to me since I was counting on it to accommodate a child in the 5 point harness for above the normal height. I'm going to have to return it. It's a nice seat, very sturdy and safe feeling, but it isn't able to be used as described. Albee was very prompt, and did their part. This problem is with Diono. They need to be realistic in their height accommodations.
ProsIt was very sturdy. Heavy. Well padded! Nice color. Albee did their part. This problem is Diono's specifics not being realistic.
ConsWon't accommodate a child over about 45', even though it states up to 57'. I do have to pay for return shipping šŸ¤

Special needs toddler
My special needs grand daughter is now 5. She will need to be in a car booster seat for many years to come. This does not make her look like a baby but a big girl. I searched high and low for one that as her Nanna I could help her get in and out of. I LOVE it! I told my daughter to come to this site and see if you have any more to replace hers.
ProsSpecial needs grand daughter can pull herself forward with ease and slip off the front till her feet touch the floor. Good grabbing sides for her to pull herself into the seat. The release buckle can be undone with ease for Nanna's older hands.
ConsWhen my grand daughter fell asleep her head had no place to rest, (rolled forward), like a car seat that reclines somewhat. But at age 5 that is not what most children need.

Just what we needed for extended rear-facing
We bought this to replace a Britax with a lower rear-facing limit. Our son is close to 35 lbs and over 37 inches tall at 2.5 and we wanted a seat where he could comfortably rear-face for at least another year. With the Rainier's 50 lb limit, we should be good to go. It fits fine behind the driver's seat on our Chevy Equinox, but I could see how it might be a tight fit without the angle adjuster on a smaller car. It's much easier for him to get in and out of by himself, and he seems to have a ton of leg room. It was a little tricky to install using the seat belt, but we managed to get it tight enough after some finagling. I would definitely recommend this seat.
Pros50-pound rear-facing limit Easy for child to climb in and out of
ConsSomewhat difficult to install Somewhat difficult to tighten straps

Amazing Seat!
This seat is great! Rear faces until 50lbs (which keeps my petite kids rearfacing for quite a while!) and then harnesses until 90lbs, then turns into a booster! Not to mention the amazing saving I got from Albee Baby! I will always shop here from now on for gear!

I regret getting car sear
I originally had the Diono RXT. We switched to the Rainer after a car accident. The wide head wings make it hard to install next to another car seat. The biggest issue is that it's impossible to get the straps tight enough. I have watched several videos and read online tips, and neither myself nor my husband can get it to tighten to the point where we can't pinch the strap on the shoulders. If you can't properly secure your child in the seat it doesn't really matter how expensive the seat was.

Amazing Car Seat
You can't go wrong with Diono. Their seats are durable and very safe. They are also slim so you can fit multiple car seats in your car. I love the easy fold and carry feature. The colors are great and the seat is comfortable and it is easy for my toddler to get in and out of.

The ONLY seat I will every own!!!
Having an 11 year old I have used many seats in the past. They were garbage! When I had my second child I researched and found the Rainier. Yes it is heavy but that is the steel alloy frame and I am ok with that as it only increases the safety for my child. The seat is easy to put together and install ( I installed 2 in less than 15 minutes in 2 different vehicles). Yes you read that right. I own 2!!! LOVE LOVE LOVE this seat and the ability for extended rear-facing due to the higher weight limits!

Should of bought it to begin with!
I care for my granddaughter daily and bought another carseat brand. It was fine, as she's grown I have found that it had become increasinly diffcult to get her in/out of. Her parents have had the Diono RXT from the begining, I should of bought this from the begining! She looks so much more comfortable, and the ease to help get her in & out is wonderful. We LOVE this carseat and cannot say enough wonderful things about it. We are expecting our second grandchild, planning on purchasing the same Diono for him. Thank You

Great car seat
We love this car seat, except for the fact that my daughters head ALWAYS falls forward when asleep. We even bought the diono angle adjuster, but it didn't work with our seats. She's still rear facing and would always wake up crying because her neck hurt. Had to put this car seat in our secondary car, and put our maxi cosi pria in our primary car until she faces forward.

I recommend this carseat to Everyone!
We actually bought this carseat as a spare for my parents to have. I was really fortunate that this came in to the store I work at as a return (never opened, they just changes their minds) so I took a chance a bought it, despite being thrown by the price. I had read the reviews and they were All phenomenal. Once I got the carseat out of the box to assemble it for transportation, I knew immediately my parents weren't getting this one. The padding in the seat alone is Amazing. The straps are so heavy duty and even the seat harness is padded and super comfy. My daughter sat in it for over an hour in the living room! It's heavy, but that's due to the solid steel frame (BONUS!) And we don't move it much anyways. The anchor attachments are Awesome. No terrible clips! Happy to know Diono is actually based in Seattle (We live across the sound) just in case. Really great product, absolutely blows away the Graco convertible carseat we let my parents have for our daughter instead!

head rest sits too low
This is a good product for younger children. I'm a bit concerned about the size of the seat for when my eldest is ready to transition to a booster seat. The head rest is already low for him, his shoulders are almost touching it. As well, the width is starting to get snug - he's not even 4 years old. The seat seems comfortable for him right now. Another concern is that the pull belt, to tighten the harness has started to fray... shouldn't do that.

we were recently in a car accident and i was advised to purchase all new car seats. but we currently own this one for our 4 year old and she didnt move an inch. she was so secure and safe. i just purchased 2 of the new models because i will not put my children in anything else after seeing our 7 year old daughter thrown forward in her current booster seat. well worth the money!
Consit is heavy but i would not say that is a con. it is just made extremely well.

Love it.
Bought this seat to begin transitioning my 12 week old son into... he's just 16 pounds but I want him to have a safe car seat that would be more comfortable than the seemingly cramped infant carrier/car seat I received as a gift at my shower. I really like this seat. And thankfully so does he! He fits well in it and has fallen asleep in it several times without a problem just as he would the infant seat. His head does fall forward slightly when he sleeps but I don't think it will cause him any strain... the harness padding is so thick that it keeps his head more upright than side-lying. I love the fact it's tethered to the car fame... literally this thing does not budge after being properly installed! (Which was super easy after watching Car Seat Lady's YouTube tutorial) I think the midnight color is fantastic, I love black and the seat is functional and appealing to the eye. I can't wait for him to grow with this seat, I'm proud of my purchase. Feel I made the right decision!

We like that thus car seat will keep our daughter safe and rear-facing longer than other seats. It seems very comfortable. Only concern to have is it you have a tall driver, this seat does have a pretty far back position for rear-facing or recommend the seat wedge to elevate it.
ProsGreat head support, easy 5 point harness
ConsRear-facing angle of seat can cause it to not fit in some card properly without the seat wedge sold separately to place under the car seat.

CPST in love with a car seat
Love the slim design of the car seat. We have taken our Diono with us in several cars and rental vehicles. With the use of the angle adjuster (purchased separately) I am able to install in smaller vehicles (2009 Kia Spectra) with plenty of room for my large 5'4 frame and still allow more than 12" between myself and the front airbag and room for the passenger as well. We have also taken the car seat on the plane, with narrow seats. It fit quite well, but I would HIGHLY suggest purchasing the backpack and additional strap, as it is HEAVY! I'm a single Mama and dragging a 30 lbs kid and a 30 lbs cars seat. Better if you're installing in one vehicle and leaving it. LOVE LOVE LOVE the rearward facing tether, which limits the head excursion in an accident, as so few American car seat manufacturers offer this safety feature. My child is still REARWARD, having turned 6 this month (38 lbs and 39.5"), and is still fitting within the specifications for rearward, let alone the 90 lbs limit for forward facing. When forward facing a friend's child in the vehicle, it allowed other passengers ability to freely pass through the rear seating space, and allowed him to even rearward face at 4, and 48 lbs and 42" (he's a big boy). As previously mentioned, the ratcheting system is a pain, wish it could be better, and a no-rethread harness would be a Godsend for this.. We have had the Radian car seats since our first Sunshine kids 80, and have loved them ever since.

Beautiful like the picture
Looks very luxurious and feels very comfortsble and secure. It's a heavy seat, as expected. Installation was easy and straight forward. The angle adjuster foam is very useful, you should buy them together. It adds an extra step to the installation process which could be a minus. I also find it difficult to loosed the latch belt when removing the seat (quite impossible actually, my husband had to use a screwdriver to do it). Other than that I really like the seat and so does my 16 month old.

I love the car seat but...
I love the car seat. It seems sturdy and is a nice fit for my son. It was just hard for me to get past the fact that I was sent the wrong color. My son's favorite color is green so I ordered black forest and I was sent the one with gray in it. It was disappointing which is why I could only give it four stars instead of five.

Yes, it's heavy and really tall so not the easiest to maneuver. My almost 3 year old loves that she can sit rear facing with her brother, has plenty of leg room and is comfy. It's rally narrow and fits 3 across easily in my Acura. Love, love, love the print as we're a Bama family. The fabric is soft and foamy so it seems really comfy.

Heavy but such good quality
I love this seat. It is super heavy so if you have to switch it between cars frequently then it's not the seat for you but it feels so soft and the quality is great. I love everything about the seat. Also, I didn't find it difficult or complicated to install. The only other thing is go ahead and get the seat adjuster and include it in the costs when deciding which carseat to get. But overall I live this seat and my daughter seems to as well. I definitely recommend.
ProsSo comfortable and such good quality and sturdy.
ConsVery heavy and you need to buy the angle adjuster cushion which is dumb. It should just come with it.

Great carseat
I decided to try the Rainer since I read it last 12 years and our Radian Rxt last 20. When it arrived, I was super happy with the look and feel of the material! Since already owned the radian, I knew the basic set up and got it done rather quickly. The only "issues" I had was that I couldn't figure out the body and head insert very well and moving the crotch strap still takes forever. My 10 month old loves her new seat and my Oldest is jealous she doesn't have a diono seat.

Best car seat on the market
I am a certified CPST through SafeKids International and see and install car seats every single day. This is absolutely my favorite seat. I have multiple children in car seats and love that I can fit three seats side-by-side and keep them rear-facing through fifty pounds. Through my law enforcement experience i have worked a vast number of vehicle collisions with varying degrees of severity and would never purchase any seat but the Diono to keep my babies safe. Highly, highly recommend all of Diono's line of seats. Remember, a $300 seat used from the age of one through the legal age they can leave it according to Texas State Law, eight years old, come out to only $42 a year. That should NOT be too much to spend for your child's safety.

Amazing Car Seat!!
I spent so much time researching and reading reviews on car seats and finally decided on this one and am so glad i did!! Needed one for my 4 year old that would be safe and more comfortable and convertible for her growing needs. Got it faster than expected and was very simple to put together and set up in the car! Did alone and it was easily the most simple i have used since becoming a parent or even when taking care of kids in the family. Sturdy, great side impact protection, very soft and cushioned fabric and seat. Even my 4 year old says its "super comfy" And she loves it a lot! There is easily double the space freed up now in my back seat from her old convertible seat which is awesome! Highly recommend this all around! Wish i had gotten it sooner!
ProsEasy to set up, very compact and leaves plenty of room in the back seat, great side impact protection, wonderful leg room for long legged kids and very soft and cushioned.
ConsWish the cup holder was better, does not stay put and we always take water with us and she cant set her water near her so that is unfortunate.

Great price!
My daughter already had this car seat & I just wanted one for my car (it is very heavy & awkward to change from car to car) so I knew what to expect. The price was great & I just ordered it without first reading the reviews. After reading the consistently negative Yelp reviews I was more than a bit worried.....I received the car seat in about 7 to 10 days. Nothing wrong with the packaging or the car seat. Everything was great & I would definitely order from the company again.
ProsWell made car seat with good padding. It is narrow so it does not take up a lot of seat space (I have it in a Jeep Wrangler). If you don't have to move it from car to car this is a good option.
ConsThe seat is heavy & hard to get in & out of the car. Also, if you have it front facing, which we do for a 3 year old, it does not recline at all.

Heavy and hard to install!
My coworker recommended Diono to me because she loved it and was impressed with the steel frame! So I took her advice and bought a Rainer In a houndstooth! The Car seat is made very well and loved the safety and design features but it was quite difficult installing in my Nissan Pathfinder!! After 30-45 mins, my husband was able to install it without the seat wobbling back and forth! I wish it would have two latch devices on both sides! We decided to keep it but not invest in other ones for our youngest!

Very sturdy and secure!
Prior to this purchase, we were dedicated Britax customers. Our youngest son has grown so quickly that he outgrew his car seat, but is too young for a booster. Therefore we looked for a convertible car seat that still provided us with the security of the 5-point harness and would be a high-back booster, then backless booster. The Diono Rainier gives the highest weight and height tolerances for convertible boosters, while providing the flexibility to adjust the hip area for our growing boy. Some improvements are adjustments that the Britax has that makes the installation and maintenance much more user friendly. Firstly, the strap adjustments on Britax use a slider bar system vs restrapping on the Diono. Also the UAS clips are permanently affixed to the Britax car seats providing better stability. Overall, we would definitely recommend Diono and would purchase again.

Airplane ready
I got this car seat because of its material and slim design. It is easy to use in an airplane. It can also sit 3 in a row in the backseat. it is very sturdy and easy to adjust. My daughter is 2 and uses this rear- facing, depending on which vehicle we are in. The rear-facing position takes up a lot of room. The only con I have is that I do not like how the seat tightens. It takes a while to 'click' to the right tightness.
ProsSafety. Airplane use. Slim design. Can fit 3 in a row backseat. Very sturdy material.
ConsHeavy. Have to 'click' to tighten restraint- not as fast as just pulling it tight.
Best UsesEveryday use. Airplane use. If need 3 car seats- can all fit in backseat because of slim design.

I use the car seat everyday! we had a winter baby so we used a carrier at first then transferred to Diono, we love every min. Our son is safe and comfortable and no longer cries in the car. We are looking at buying a second one for our 2nd car. The car seat is well made, and securely and easily can be taken in and out of the car. When used in rear facing mode it does take up a bit of room (fits in ford focus) but forward facing can still fit 3 people in back. I cannot tell you how much I love this carseat. It is easy to transfer and take the baby in and out (even kicking toddlers!)
