Booster seat in third row

I’m currently using a high back booster seat in the third row. It will be a temporary thing for me but how many of you run a high back booster in the third row full time? What brands/models work well back there?

No tether and no latch system in the third row makes me feel un easy.

 

According to the NHTSA, a high back booster seat does not require a tether or latch system.

 

You are correct sir.
Just trying to see if there are better options than the Diono I’m currently using that work well with the 4R 3rd row.

 

Also, the LATCH system is in no way superior to a car seat/booster seat/etc. correctly installed with a standard seat belt. Had a buddy that was all hot and bothered about LATCH until he realized it's only beneficial if you can't install a seat correctly without it.

Edit: sorry, I know that didn't really address your question about the particular seat you are using.
