Query: Sack of lumpy foam

I am shocked that there are so many positive reviews of this pillow. It is simply a rolled up sack of lumpy foam bits and no amount of tossing and fluffing made my pillow resemble the one in the picture.In all fairness, I thought I was buying a pillow with an inflatable core (since I came to it via a search for "inflatable pillow"), which this is not. I realize, that had I read the description more carefully, I might have discerned that "compressible" is not the same as "inflatable". Nonetheless, it was neither comfortable or small (when packed) as I had hoped.
