I am a very sensitive pillow person-  too firm and I have neck pain which leads to head aches.  It's hard to buy pillows online, but the reviews were helpful and these are pretty good.   They are a little firmer than I expected but seem comfortable enough when I tried them out.   May go back to feather pillows in the future, but these are quality and the order process and delivery and price were all great.

Edited now to say that after a few days, these pillows fluffed up even more and became extremely thick and firm.  I can’t use them at all.   There is nothing soft about them.  “Soft density” is a huge misnomer.   They are like thick rocks.
