    • Good buy
Color: Black Jet
I like the quality and durability of this car seat. I’m using it for a toddler and they’re used to a big car seat like the maxi cosi or graco convertible ones so this was an adjustment in the seated positioning. As it is smaller and not as elevated. They fit well and it feels secure and easy to adjust to height. I got it to fit in my sante fe. It’s in the middle of two infant car seats on both sides. The convertible car seat was too big to fit with the infant car seats too. I plan to buy 2 more when my infants outgrow the buckets. ... show more

    • Good
Color: Black Jet
Our son and his wife say this is the best brand car seat. It's narrow enough to put 3 kids in the rear seat in car seats. That's the report from the users, not mine since we're too old to have kiddos but sure are enjoying the grandkids 🥰

    • Amazing car seat
Color: Red Cherry
This is our third Diono car seat. We had 2 of the earlier models. YES, this car seat is heavy and that is why we bought it. We didn't want a car seat that rocked all over the car when we made a turn. It is very easy to install. I am 5'1 and it took me about 10 mins to put it in the car. This is definitely not a car seat to be traveling with UNLESS you're making a road trip. The cover is not that difficult to remove and put back on but if your scotch guard it and vacuum your car seat you won't have to do it that much (pro tip). My daughter loves her car seat so much. ... show more

    • Great product!
Color: Purple Plum
This seat is VERY heavy. My son seems to be comfortable in it. It has many quality safety features. The fabric is a vibrant color, we got both the blue & purple. I would say I’m afraid to wash it as others have said it doesn’t fit properly after and I used just a wash clothe on it and can see that after just 4mo of use the fabric looks worn. The install was difficult & I’m really not sure if it’s exactly correct. We turned the seat forward facing for a better fit as our son is right at the mark for being forward facing. I have a video that won’t upload , YouTube has videos as well. ... show more

    • Could be better/Britax comparison
Color: Gray Slate
I bought This because I needed The thin profile to fit three across.(have a backless booster and Britax frontier in a smaller car) I bought A Britax blvd as well which is also a thin profile and has similar safety/steel enforced a few years ago for similar reasons. They both have pros and cons. Britax blvd click tight - so easy to install, no re thread harness. Adjustable recline. Cons: fabric isn’t as nice, higher profile. Cup holder is useless. Diono: pro: lower profile, anti rebound bar, nicer fabric. Cup holder is easier Cons: cannot adjust recline, have to re thread to adjust harness, the head rest is awkward/bulky for smaller toddlers. The harness straps are bulky and my toddler easily takes them off to play with. Very hard to install. The legs for the RF plastic base hit my latch connectors. Could only install correctly in middle seat. Overall-I feel stuck with this because it’s a lower profile than the Britax and it works for my car. If I didnt Need every single last cm of space I wouldve went with the Britax. They are very similar in that they are not very wide but for my car the lower profile made a difference. For the price I wish They would add no rethread harness and an adjustable recline. My toddler doesn’t want to be laying back so far while RF. ... show more

Fits great rear facing in my Jeep compass. You will need the bottom block (not sure what it’s called). My toddler looks comfortable and happy.

    • Does not fit 3 across in a 2008 Forester
Color: Purple Plum
The three across would probably fit well in a different car. But for me, in a 2008 Forester getting three car seats, 2 were to diono's and an infant car seat did not work. The diono's were too tall for where the support bar behind the rear door was located. They did not fit in a middle and side orientation as it pushed the infant seat at a weird angle that was not safe. So if you were looking for a suggestion for a 2008 Foreste: get one Diono, and two Graco slim fit lx. Those do fit in only two combinations, but they do fit. We love our Diono and that's why I had tried it as a 3 cross option originally. ... show more

    • Sturdy car seat
Color: Purple Plum
Review Image by Arlen T. Arlen T.
Very sturdy car seat ! Looks nice and it’s well made with all the safety things it has. If you have a regular car or even a compact suv this won’t fit rear facing , I have a Kia telluride it’s a medium size suv and it fits just right but also because we are not tall people 5.5 5.6 the tallest so there is the right room for the front seat , if you are taller I believe you’ll have your legs squished in order to properly position it. So FYI before you buy it , other than that I feel is the safest car seat that you can find. ... show more
