I am a terrible sleeper. I toss, and turn most of the night, and part of it is because I hate when my pillow gets hot, or needs to be readjusted. This pillow has been a life-saver. I was worried I wouldn't like the memory foam, especially after hearing so many people can't stand it. Well, that's not the case for me. This pillow is so thick, but the memory foam adjusts perfectly to the shape of your head, and at such a slow pace, that you don't even realize that it's moving, and before you know it, you're asleep. I haven't woken up once in the middle of the night to adjust my pillow since I bought it. Now the only problem is, not wanting to get out of bed!
