I received this pillow for free from the manufacturer as a product test. I've been using a "normal" cotton-stuffed pillow for years, so it took a couple of nights to adjust to a new type of pillow. Now that I've been using for a while, I don't want to switch back!
I generally lay on my back for a few minutes at night before rolling onto my side to go to sleep. While the design reminds me of a beanbag (small, shift-able pieces inside), I was pleasantly surprised to find that it provides very good support to my head and neck in either position. The shape of the pillow can be adjusted to prop the neck comfortably.
The accompanying pillow case is very soft on the bamboo velour side. To me, it feels similar to the minky fabric used for baby blankets! The spandex side is more stretchy/smooth. It gives the pillow a "cool" touch.
