Awesome sturdy car seat

By Holydiver

from San Antonio, TX, United States

Comments about Diono RadianR100 Convertible Car Seat:

I love this car seat. While is quite heavy, I like that it feels extremely sturdy and safe. It is very comfortable, confirmed by my very picky son, that jumped in the seat without any complains. Two great features that I would like to showcase: - quick disconnect for the rear-facing straps - no more sticking your fingers to reach the clip between the back seat and the backrest - narrow profile - no more fighting to find the seat belt connection under the car seat to be able to buckle-up. Overall is a great value and gives me the confidence of knowing that my son is very well protected during our trips.


love this heavy car seat

Comments about Diono RadianR100 Convertible Car Seat:

I've had this carseat for a few months and I love it! I know my son is very safe because of the heavy steel frame. I love that it folds into a backpack for easy traveling! Way better than the other car seats I've purchased in the past.

It was everything I expected. Pretty heavy but extremely solid.


Problems with top tether

By Kcdyson

from Atlanta, GA, United States

Comments about Diono RadianR100 Convertible Car Seat:

Great product but when I took it to the fire station to check the installation they could not remove the top tether buckle. It took them 40 minutes and they had to use pliers to unfasten the tether buckle. The fireman said my tether hook on my Toyota Camry 2007 was to long for the tether. I put the top tether on rather easily but hadn't tried to take it off and this was a major issue for the firemen.


Great for grand child!

Comments about Diono RadianR100 Convertible Car Seat:

I got this to use when my granddaughter who is 4 yrs old is with me in my car. My daughter put it in for me and it seemed simple to do. Will not be using it all the time so I can't say much about it. Will be able to use it since the younger grandaughter just turned one.
