Knee pillow recommendation

Hi folks!
I want to buy a knee pillow! I always put the blanket between my legs, and because of this, I uncover myself. Sometimes I even wake up with my throat ache. Choosing out of these options. What do you think about the third one? Looks quite comfortable. Waiting for your responses.

Welcome,

Probably not the highly insightful answer you’re looking for, but that #3 at least looks fairly comfortable. The first 2 look fairly thick and I dunno how comfortable. But they were rated higher for some reason. Being a side sleeper myself, I should probably get one on that list.

Maybe a standard relatively flat pillow might be OK if you want to save a few dollars. Just a thought.
