I’ve found that the main advantages of my memory foam pillows are that they regulate heat much more effectively than any other pillow I’ve tried, and they automatically mould to the profile of my head and neck, and retain that profile much more effectively. The upshot is that I find them far more comfortable than other types of pillow. As long as the pillow is an actual memory foam pillow, and not a cheapo one, which has a layer of memory foam, over a standard foam centre, these are horrible, and don’t work well at all. You get the worst attributes of both type of pillow, and more expensive than the very cheap foam type.
