1. The Head Wings For RXT
Only the Diono Radian RXT has a head wing for older kids to lean on when they sleep. Not that it is not safe without one – because all three are built equally safe and sturdy.
Note that the head wings can’t be used until your child is in the third slot. It will also level with your kid’s jaws.
When you are still in the rear-facing mode, the head wings doesn’t matter much. That is because the kid’s head will naturally fall a bit because of the recline.
2. The RXT Is Heavier Than The R100 And R120
Both R100 and R120 weigh 25 pounds, whereas the RXT is 27 pounds, just two pounds heavier than the two.
3. Weight Limits
Here’s a table of side by side comparison between the height and weight limitations of the RXT/R120 and R100.

4. The Memory Foam Under The Bum For RXT and R120
The R100 doesn’t have the added foam for additional comfort in the bum area. Again, not that it is not comfortable without it. It is only one of the added bells and whistles to justify the added cost for the RXT/R120.
5. The Infant Support Pillows For Both RXT and R120
For parents who are wondering how the RXT/R120 is any better than the R100, the lack of infant support pillows in the R100 might just be a deal breaker.
Younger babies need all the support they can get especially in the head and neck areas.

6. Added Structural Support for RXT and R120
Because of the additional 15 pounds on the weight limit for the forward-facing mode of the RXT/R120, Diono has improved the structures of the seat to adjust the support accordingly.
7. Cool Colors Are Only Available For The RXT
R100 and R120 have limited options when it comes to colors. The colors available for RXT are more than 3x compared to the two.
8. R100 Doesn’t Have a Cup Holder
If that is something important to you, it is worth noting that R100 doesn’t come with it.
9. Price Difference
The Diono Radian RXT is the most expensive, followed by the R120, and the cheapest is the R100.

There is a debate about the importance of the head wing when it comes to safety. They say it’s better to get the RXT because should there be any collision from the sides, it will serve as an added protection for your child’s head. A very good point when you come to think of it.
But some parents who are after the comfort of their growing children seem to be bothered by how the head wing can sometimes hinder their kids’ shoulders as they grow.
The RXT’s head wing is movable.You can slide it up and down to adjust to kids’ heights so that can help with the comfort.
Safety versus comfort. I’d go with safety.
While the RXT/R120 have a higher rear-facing weight limit (5 pounds more than R100), all of them have the same height limit when it comes to both rear-facing and forward facing mode. Most of the time, children outgrow seats height-wise first before they reach the maximum weight limit.
The added 15 pounds in the forward-facing weight limit of the RXT/R120 is definitely a plus. You can have your child seated in forward-facing until 80 pounds in RXT/R120 versus R100 which only accommodates up to 65 pounds forward-facing wise. But then again for forward-facing, the height limitations of all of them are the same which is only until 57 inches.
I believe the infant support pillow is important especially that newborns and young infants’ heads and necks are vulnerable and need all the support they need. Something that R100 does not offer.
While the cup holder is not necessarily crucial, it is nice for your kids to be able to have an access to their drinks anytime.
The added foam padding in the bum area is something that can be significant when you are always traveling long distances.
While the available colors are something that can easily be ignored, it is still worth noting.
