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 Fairly easy install, instructions are hiding but there!

5.0 out of 5 stars Fairly easy install, instructions are hiding but there!
Reviewed in Canada on July 1, 2021
Installed this rear-facing into my F-150 last night.

The instruction manual IS there and it’s located inside the carseat at the back in the upper left side, there is a small symbol showing a book on the seat cover and if you unbutton the cover you can access it easily and pull it out (see my photos).

I used the UAS strap to secure it but it definitely was not tight enough, seems to be common in my truck. But once I also attached the tether by following the instructions and looping it around the seat in fronts track, it appears to be tight enough now. I am going to double check it and if needed add the seatbelt as well. This is only the third car seat I’ve ever installed before so I’m not a complete expert.

My daughter hasn’t used it yet but I will update my review once we use it for a while. I bought this particular car seat because it looks simple and it doesn’t block her view much and it feels very comfortable just from me pressing on it. And it is supposedly good for extended rear-facing. It is also a nice looking car seat from a reputable brand.

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.

2.0 out of 5 stars Good luck getting it to fit in anything but the largest SUV/Van
Reviewed in Canada on October 17, 2021
It looks like a great seat, very solid and heavy duty. Unfortunately it doesn’t have any recline adjustment and the back is very long. Because of this, it will only fit rear facing in very large SUVs or minivans. I have a smaller SUV and I had to put the front seat so far forward that it cant be used. It is narrow though so you could get more than one side by side if legroom is plentiful. It should be fine in smaller cars in the front facing position, but you can forget about putting it rear facing. Another gripe I have is that they hide the instruction manual in a pouch under the cover. Of course I found it after I thought it was missing and printed out the PDF version online. The manual tells you where to find the hidden manual - yeah. That’s why there are a bunch of reviews here saying the manual was missing. It looks like a great quality seat, but I had to return it as our child has to sit rear facing. Be sure to do your research and measurements before buying.
