Awesome booster
July 25, 2015
This item has a very narrow base and fits perfectly in my Mercedes Benz glk 250. I ordered this booster specifically because we were having a problem fitting our old booster in the back seat and not being able to access the buckle for the seatbealt. This booster completely solved this problem and saved us a fortune by not having to buy the one directly from Mercedes. The memory foam is a nice touch and the seat side wall expander is great for larger kids.
Narrow base, elevated
Best Uses:
Mercedes glk250, for larger children, smaller suv or smaller car.

We purchased this seat for my husband's car, he drives a tiny Civic, and it fits so perfectly in the backseat! It's also much easier to buckle our littlest into than what we previously had. We will be purchasing one for my car soon.

Great car seat

Very sturdy, a bit on the heavy side but this thing is a tank. This seat has good padding and is very comfortable fit my little one. I actually got a compliment from someone on what a nice looking car seat it is.

Great Seat!
June 15, 2015
It's a great car seat. I wish I were a little higher and the back is very long so it takes up quite a bit of real estate between the seats. I do like the slimmer profile since I have a smaller car. It is heavy and really large so we won't be using for travel like I had hoped despite the folding feature.

Not too busy
June 10, 2015
When I saw this color on my computer screen I almost got dizzy, but I kept coming back to it. I am really glad I ordered it. In person it is nice and goes well in my car, it isn't too busy and it doesn't show stains like darks colors do. I bought this for my 10 month old boy, he is my 3rd child. I have 2 older kids, 10 and almost 7. I used Britax with both of them. I liked the Britax, but I wasn't excited about installing it in our car rear facing. Since back in the day it wasn't recommended to rear face for so long. We always forward faced the seat as soon as we could(usually 1 year). I guess we just love our youngest more since we plan on rear facing him for 2 years. I know everyone says we should do it even longer, but we will see. We have never wrecked any car so I have yet to rate a car seat for that reason. The Diono Rainier is heavier than the Britax(I've owned ALL models-ok maybe they are a bit comparable) but it is sleeker. It fits nice in our Acadia with plenty of room. We installed it in the middle and had the older boys on either side. It worked great, but here comes the cons. The car seat is TALL, it blocks the screen in our car so our boys couldn't see it. It also blocked my mirror so I couldn't see the baby in the car seat. I think we could have found a work around for the mirror problem. So I moved it behind the drivers side. I did not have to move my seat forward to compensate. I am 5'7'. My baby seems happier in it, as he can see out a bit better. He is still inclined enough to sleep in it. My almost 7 year old wants one. We are thinking about it, since he is only 46 inches tall and 40 lbs. We travel long distance and this car seat is comfortable for the long rides. I think I am mostly impressed with how sleek it looks in the car. I still like Britax, but I like how this hardly takes up any seat room. If we do get one for the middle child we won't have a problem fitting all 3 kids in the back.
Sleek, soft fabric, very comfortable seat.
Very tall. Heavy

Excellent seat!!

We bought this seat when our baby was 4 months old. We decided next baby we'll skip the infant bucket seat completely and start off with a convertible seat like this one. We babywear everywhere we go anyways and carrying around that infant seat is a huge pain! This seat is perfect for our needs. It's not as user friendly as some others, but it's completely worth it with it's high rear facing height/weight limits. This seat should get our son Rear Facing until well beyond 3 years, hopefully passed 4 years even! Sure, it's heavy, but that's what you get for a high quality seat that's made with steel.
High Rear Facing limits
The manual could be more helpful so that the seat was a bit more user friendly

Great Car Seat! Glad we chose!

Great car seat. Love the carrying strap and ability for the seat to fold up. We travel a lot for my husbands job so this was a no brainer! The seat does recline quite a bit in the rear facing position but it fit in our car fine. Great ease of use and seems really durable. The color is perfect and will grow with our son! Glad we chose this!

Love this Carseat!

I purchased this to use after my 4 month old daughter out grew here infant carrier. I was looking for the best safety ratings, design, style and lots of other things in a convertible car seat. I chose this one because of the safety ratings and the fact that I can keep my daughter rear facing till up to 50 pounds. I love how this will be the last car seat I have to buy her and that she can use this until she's 120 pounds. I really like the houndstooth print and I've gotten a lot of compliments on her car seat. We have the Radian RXT in purple for my other vehicle and love that but I'm glad that we got the updated model of the Radian RXT. This carseat is made of really good quality love it hands down!
Quality made nice prints super comfy padded chest straps folds flat for easy storage
pretty heavy so I don't recommend transferring to and from car to car. (we upgraded from a radian RXT that we leave in our other car)

Easy to install
October 4, 2014
The carseat was very easy to install with the seat belt. I really like that it folds easily for travel and has extended rear facing capabilities. It fits very snugly in my 2013 Elantra. The seat materials are soft and the memory foam is a nice touch. The belt clip is quite large. The strap to tighten the restraints is a bit difficult to use while the seat is rear facing.
easy to install
