Most solid car seat I've ever installed.

By kenmacd

Comments about Diono RadianR100 Convertible Car Seat:

I've installed multiple other car seats and none has installed as solidly as my R100. It's easier to pull tight then any of the others and once installed it don't budge. It feels like it's a part of the car. When tightening be sure to un-velcro the side of the seat and pull the belt through there (like the instructions show). I'm using it forward facing in a 2009 Subaru Impreza.


Excellent for the price

Nice fit in car!

Comments about Diono RadianR100 Convertible Car Seat:

I bought this because I have a jeep liberty, which doesn't have much space in the backseat (I feel like, but I'm 6'1"). I'm very happy with it. We have it rear facing and in the middle back seat and the driver seat and passenger seat are able to be back all the way. We have it in the middle because it reclines quite a bit when it is rear facing and if we hook it up to our latch then we have to move the front seat forward, which just isn't an option because of our height. It's so easy to set up. And we are looking forward to taking it with us on the airplane, especially because it folds up so nicely. Our baby loves it too. I'm very happy I researched this seat and found it for a great price! I plan on buying more when we have more children.


Great seat, but some important shortcomings

By Karen

from Montréal, QC, Canada

Comments about Diono RadianR100 Convertible Car Seat:

We bought two of these car seats last year, one for each of our sons. Our car is a 2007 Toyota Corolla. First, I should mention that we would like to have another child. Despite claims to the contrary, I doubt we will be able to fit three of these car seats in the back of our Toyota Corolla. Nonetheless... Our oldest is 4 years-old and forward-facing. This seat is great for him. He's comfortable in the seat. He can also easily climb in and out of the seat, but he cannot undo the straps himself (which is a good thing!) Our youngest is 18 months and rear-facing. We also like the seat for him, but I have a difficult time tightening the straps with the seat in the rear-facing position. I manage, but it's awkward because there it little room between the back seat of the car and the slot where the strap comes out of the bottom of the car seat. I've noticed that this is a common complaint with this car seat. Also, I think that the manual should address the following issues: - clearer tips for knowing whether the straps are tight enough - tips for knowing whether your child's clothing (e.g. snowsuit, sweater) is too bulky for wearing in the car seat - information regarding how much the back of the front seat can touch the back of the car seat when the car seat is in the rear-facing position I would also like to have more information regarding whether the "head rest" available with other, more expensive Radians improves the safety of the car seat or whether it is a simply comfort feature.


Love it!

Comments about Diono RadianR100 Convertible Car Seat:

We love this car seat! Its sleek design makes it easy to get our daughter in and out and she is very comfortable in it. It is very durable and gives us the security of safety with its construction.
