Diono Radian RXT as a booster?

  Diono has never said their reasoning, but carseat techs all say that you must follow the manual. There's a very good chance that for children under 50 lbs it did not pass testing as a booster, so that would be why there is a 50 lb weight minimum. Unfortunately very very few kids hit 50 lbs before the tops of their ears go over the top of a radian shell, so it's basically useless in booster mode for most children.

  Thanks @penguingrrl‌ I'm going to have to look carefully the next time he's in the seat bc it seems like he's already getting too tall for it even though he's nowhere near the 57" maximum.,,,,he must have inherited my long torso!

  My girls both inherited DHs long torso (not from me; I'm just a hair over 5' and there's nothing about me described as "long") and both outgrew the radian heigh-wise right around 4 years old and 40 lbs. Very few kids get anywhere near 57" before outgrowing the radian, though. Not sure if I've ever heard of a kid who did make it to over 50" before their ears went over the top.

  All of this. There is really only one all in one seat that actually functions in all modes and that is the Graco 4ever. All other seats marketed as AIO do not work in at least one mode.
  
  How old is he? I recommend kids stay harnessed until they are at least five even if they meet height and weight requirements simply because the vast majority of four year olds are not mature enough to sit appropriately. There are however a few exceptions and if you're able to see he sits correctly all the time and he's outgrown his seat in harnessed mode, you can transition to a different hbb.
  
  ETA: I'm a CPST
  
  CSFL has a good article discussing booster readiness.
