Memory foam pillows come with various types of foam inside. The typical pillows on the market today have either shredded foam, solid foam, or contoured foam inside. Most people that try memory foam pillows are unhappy with the support of comfort of the traditional down filled pillows. Sleeping discomfort can lead to pain in the head area, neck, or shoulders. Quite often, memory foam is a good option to resolve these issues. If you find your current pillow to be unsupportive or sinking too low while you sleep, you might consider trying memory foam instead.
