I bought these pillows after checking out all the prior reviews, and finding that people who labeled themselves "side sleepers" liked these pillows best. I had previously purchased a thick, fluffy down pillow at at local bedding store, and didn't like punching it down (no pun intended) to get a good fit. Between the reviews and product description of the central feather core, I thought I'd get a better fit. Sadly, I found these well-made, soft, fluffy pillows sink down to near-nothingness under the weight of my head. So, instead of punching feathers for a good fit, I now find myself scrunching and fluffing to get that precise level to support my head without neck or shoulder strain. In fairness, I now sleep with both the old fat and new thin pillows, and find myself choosing scrunching over punching more often in the middle of the night. But, like Goldilocks, I am still looking for "just right."That said, if you like soft and squishy, or you have narrow shoulders (mine are pretty broad), this just migt be the pillow for you. And the covering is soft, tightly woven and well-made. I cannot discern the "circle of down" core inside the pillow, but the label seems to describe a feather inner core. (No catchy catch phrase to confirm.)
