I think my quest for the perfect pillow has finally ended.  It's firm, but cushiony (is that a word?) and holds its shape.  The polyester covering has a silky feel to it even though a pillowcase or sham will cover it. I should note that because of its generous size, it is a tight fit in a standard pillowcase.  I slept on this pillow for over a week before writing this review and can attest that it works well for back or side sleeping.  I bought this along with a new comforter and they are perfect companions.
