Alireza: Very heavy, functional and kind of big specially in rear face.
Hope it fits in my Tacoma, I haven’t installed it yet.

Amber Lynne: Feels super sturdy, yet cushioned and soft for baby as it has the memory foam inserts! Absolutely love it and I now feel safe with my baby in the car! I was skeptical of purchasing after seeing some negative reviews, but I personally love ours and haven't had any issues. It was a little hard to install, especially since mine didnt really come with clear instructions or anything, but I got it figured out thanks to YouTube and basic knowledge of car seat installations.

Andrew S: I have two of these seats; one I purchased direct from the manufacturer, and the other from Amazon.

They are a great seat. They are fully adjustable, solid construction, and the covers come off to machine wash. The fact that it's a narrow seat doesn't mean it's not comfortable; the seat actually expands if you have the room. It's also a 10 years from PURCHASE expiry, so it'll last quite a while.

The customer service from Diono is great as well. We had a plastic piece break on the side impact device, and they promptly sent out a replacement after a couple photos were sent.

The only downsides (and I don't think it's that much of a downside) are that this seat is heavy, and that's because of the steel frame construction, and the price.

At about 25 lbs it's a bit awkward to carry around, but we also bought a carry bag and it works excellent.
The cost is a bit high if you don't find it on sale, but if you find it at $430 CAD, its pretty decent deal for what you're getting.

Oscar Edid: Si lo que buscas es poder llevar a tres hijos en la parte de atrás de tu coche de manera segura, sin duda estos asientos son la mejor opción, es una inversión de largo plazo ya que durarán al menos hasta los 10 años de vida de tu pequeño, la instalación con cinturon de seguridad es sencilla y segura, no son pequeños, por lo que ocuparán bastante espacio en posición de contramarcha.

Andrew: As stated in multiple other reviews, this car seat is absolutely massive, I have a quad cab ram 1500 and the front passenger seat has to be all the way forwards for the car seat to fit in the back. However, the comfort and safety of this seat is unparalleled, with soft memory foam cushions my little one nearly falls asleep as soon as she's secured in her seat. Definitely worth the investment!

NR$JAKI: Since I purchased this for a 15 month old, I can’t attest to using it for an infant with all the additional padding. But right out of the box it’s a pretty weighty seat. The steel frame adds some heft to it and it FEELS structurally sound. If you’ve installed a car seat before, it’s pretty easy to figure out the latch system it uses; A tether up top that secures it behind the seat and a lateral belt that you snake through the appropriate holes in the bottom/back and secure the buckles with a snap to the car’s latch system on either side. One thing I particularly like is the bottom belt latch strap has pull-release loops so you don’t have to twist your wrists in awkward positions to release the belt by pushing the buttons. The only thing, is the seat is tall so we had to remove the headrest on our back seat so it would sit flush to the seat. It took about 15 minutes to install it forward facing.

Where I took off a star was the buttons for the adjustable straps to make them tighter to secure the car seat to the seat. They’re hard as hell to adjust and I had to have the hubby tighten them because I couldnt manage the leverage it takes to pull them. The button to...

Dionne: I did a lot of research into the safest built car seats, but I did NOT take into consideration the comfort.... Boy was I pleasantly surprised when my 8 month old fussy car traveller passed out on our maiden voyage in his new "big boy" seat. I wish I'd just started with this one--since he woke up when the car stopped 90% of the the time anyway!!! I can't rave about this car seat enough... I'm not in the least bit technically inclined, and it was easy as pie (ie: a frozen one you shove in the oven and say "look, MIL, I made this...I swear...".) to set up. Looking forward to the next 10 years with this tank in my back seat.

Kimberly Gross: I bought this seat for my daughter-in-law, and this is what she had to say about it:
I am a 34 year old mom of 3 boys aged 3, and 4 months. Before becoming a mom, I worked more than 10 years in the baby products industry, and so I am quite familiar with carseats. The Radian 3QXT is our fourth and most recent carseat. Our other carseats are from different brands, and we have been reasonably satisfied with all of them. That said, the Diono Radian 3QXT is something special indeed!
Let me explain why my husband and I like the 3QXT so much: 1) This carseat is rock solid. That gives us a lot of confidence in its stability and also its capability to absorb crash forces. The steel frame just seems more sturdy than other products we considered. 2) Despite its robustness, the 3QXT is actually less bulky than other similar seats we looked at, which allows us to fit 3 across the back seat—an important feature when you have 3 boys under 5 years old like us! It almost seems as though the engineers used every inch of the seat in the most efficient manner to save on space. 3) The foot attachment for rear facing installs easily and fits nicely into the seat bite of our back seat for an...
