Diono Rainier Graphite Review

Below you can read some customer reviews we compile online from users that choose the Graphite color.

“The straps are awesome! They’re huge, they don’t get tangled or twisted, and tightening and loosening them is very easy (so much easier than on my Britax or Recaro seats). The slimness of this seat is also great, especially for my particular needs. We purchase this Diono to forward-face in the back of our Mustang, which has a tiny backseat, and I’m extremely pleased by how well it fits! I had a very hard time finding a car seat with a base low and slim enough to fit in that car and the Diono is working out nicely. I like the Diono so much, I will probably purchase another for my SUV to replace my Britax. I do like Britax however the straps on this Diono are far superior which makes getting my son in and out less frustrating.”

“I bought a Rainier Graphite for our son a few months ago, because he outgrew he current car seat. We spent many many months researching different convertibles and boosters. We actually went to the store and a baby show where they allowed us to test it out with our son. I wanted something reliable, safe, and long lasting. The Rainier is exactly that. The rear facing is much longer than my other seats, and the front facing is 120lbs. So my child can use this chair for many years. It looks great too!! We are so happy with our purchase.”

“We love the car seat! It’s everything we were looking for and is allowing us to do extended rear facing. We love it so much including the graphite color we are actually planning on buying a 2nd for our other son to replace the britax. The latch mechanism on the seat got stuck and it was replaced very fast with a new seat.”

“We purchased this car seat with the knowledge that we will be traveling with it in the future on an airplane. Likes: narrow base without sacrifice to quality and safe (although never been in an accident…thankfully!). Dislikes: Difficult to assemble and safely put in car and quite heavy so traveling with this seat will not be easy. We liked the option of folding it for storage and travel although the folding option does not work without removing pieces. Overall it is a great seat. But honestly you cant have it all… safety of a steal frame comes with weight.”
