It's a standing joke in our family about my search for the perfect pillow. It has become legendary. There are dozens of dead pillows stuffed in closets around the house! Due to a serious car accident in my youth my neck is very delicate and has a reduced range of motion and just generally needs lots of support. I have spent up to $160 on a single pillow in hopes of sleeping through the night without waking up to adjust and rearrange my pillow. I doubt I could tolerate the warm side of the pillow (I am pretty hot natured) and have so have only used the cool. side. But so far, 3-4 weeks now, the pillow has provided very good support. The weight of the latex makes it more substantial than most pillows so it does not tend to wander off during the night and provides enough support that my neck does not get into a painful bind that wakes me up for repositioning. Also, the headaches that are due to neck strain have virtually vanished. Not only would I buy another one, I already have!
