5.0 out of 5 stars Worth Every Penny
By Yury WASIELEWSKI on December 27, 2021
Diono car seats are heavy and expensive for a reason. We were in a roll over car accident before Thanksgiving. Both kiddos were strapped in their Diono seats. My 5 year old was in the 3R. He was nestled in the car seat. Side air bags went off and since this seat doesn’t have a head rest support like the 3XRT my son got a black eye from the air bags. It was small but it left a mark. He was shook up but no other injures occurred. Thank you Diono for making such a wonderful products.

No damage to the seat what so ever! Due to manufacture instructions, the car seat needed to be replaced regards if the seat looks intact.

Insurance covered the cost of a new car seat and we got the exact same one. Thanks to Amazon’s available we were able to get a new one the next day.

5.0 out of 5 stars Wish I would have bought sooner
By Kayla on September 22, 2020
So I had to order 3 of these carseats and it for sure was not taken lightly as these are pricey. BUT in the end we absolutely love them. They fit perfectly in Chrysler pacifica 3rd row. First the good
--super easy to clean
--very narrow(the only issue is they are very long so if you are rear facing as you can see in the photo it sticks out alot)
--Buckles are SO easy

Cons
--i have 3 kids and have installed many a carseat. When I say these are by far the hardest I mean it. Im not sure if it was because we have so many or so close together but whatever the case this is not a carseat you Uninstall all willy nilly.
I am very happy with this carseat and if you have 3 under 2 like me, just buy it and save yourself the time of trying to make 10 other carseats fit 3 across.

After one wash the whole back of the cover is ripped! How is this product supposed to stand the test of time? Waiting to hear back if they will replace it.

5.0 out of 5 stars Love them!
By Ariel on April 6, 2021
Just bought these for my 4yo and 2yo. I had 2 gracos before these which were also great but these dionos are so nice and slim! I have a Chevy Cruze and with the Gracos I had no extra back seat space and now there is more room! The dionos also sit lower which I like because they can easily get in and out of them. I love the memory foam like seat cushion on the dionos, very soft and feels comfortable! Installing it was as easy to install as any other car seats. It took me a second to find the instructions, they’re kind of hidden along the back of the car seat. I don’t know about the easy to clean part since I haven’t had to clean them yet but while installing it I noticed the little clasps around the seat that look easy enough to undo to wash the cover.

1.0 out of 5 stars Misleading information
Reviewed in Canada on February 7, 2021
Got the chair because it says it is steel core made; even the image where this is mentioned shows a grey (like steel) core but it is not true, all is plastic just like any other chairs. The chair design in fact is not bad at all, the material that covers the core of the chair is good, but this chair is being promoted with misleading information.
