I love this pillow. It helps keep me cool all night. No sweaty pillowing when I wake up in the mornings. The firmness of this pillow is perfect for me. It supports my head and neck all night. I have noticed that I am not waking up several times a night since the pillow is helping me to stay at a comfortable temperature. I no longer have to keep an extra pillow on the bed to switch out the hot one for the cool one. Definitely a great addition to help me to get a better nights sleep.
