Hi Doozie,
cviz’s thoughs are right on the money IMO.
A pillow is an important part of your sleeping system to make sure your head and neck and upper body are in good alignment. This is iust as important as good alignment of the rest of your spine so they were telling you the truth. The cost isn’t as important as making sure it keeps you in good alignment in all your sleeping positions and that you like the “feel” of the pillow as well. There are common “needs” with pillows but personal preference plays an even bigger role than with mattresses because our face is much more sensitive to different textures, temperatures, and responses.
The pillow thread here has more information and discussion about pillows.
