Memory foam pillows sense your body's temperature and respond to it by conforming automatically to the curves of your head and neck. This gives you exactly the support you need. These pillows are different from conventional ones in that they adjust to your body--not the other way around. They don't prop your head up too much, straining the neck; nor do they under-support it, which can result in breathing difficulties as well as stiff muscles the morning after.

Memory foam pillows offer the firmness that the body needs for correct sleeping alignment. However, they are designed to cradle the head, not prop it up. There is a difference. Cradling the head allows your head, neck and shoulders to be relaxed while positioned in the correct alignment. This is the proper sleeping posture for the human body, preventing strain on muscles or ligaments. It also promotes peaceful, relaxed sleep and helps eliminate snoring.

Different Styles of Memory Foam Pillows

Memory foam pillows come in a variety of styles, offering different features. For instance, one style is designed especially to eliminate snoring. It accomplishes this by gently encouraging your head to rest to the side as you sleep, rather than facing the ceiling, which collapses the soft palate and tongue and causes breathing obstructions.

Other memory foam pillow styles include extra-soft pillows for those who don't like too much firmness; adjustable height pillows, which offer you up to four different positions to cradle the head; and contoured cervical pillows for travel. All of these pillows offer the same technology of pressure- and temperature-sensitive memory foam, adjusting to your every move, position, and curve.
