Memory foam was originally invented by NASA for use in their space program. While the material never made it into space, it made it into hospitals and bedrooms across the world in the form of memory foam. Memory foam is not only extremely comfortable, it is also very healthy for you.
Memory foam mattresses can help you to get a better night's sleep. Most people toss and turn dozens of times each night because of painful pressure points, the areas of the body that support the most weight. This prevents you from getting into your deepest sleep, and as a result you do not feel refreshed in the morning and may even require an unusually large amount of sleep.
Memory foam mattresses also prevent the neck and back from aching. Memory foam mattresses keep the spine in proper orthopedic alignment, preventing pain and improving comfort. The mattress does this by evenly distributing body weight and conforming to the shape of your body so that your back maintains good sleeping posture and no part of your body takes on too much weight.
Regular innerspring mattresses contain many allergens, especially dust mites, which many sleepers do not know about. Dust mites are microscopic critters that eat your dead skin cells while you sleep, and an innerspring mattress contains thousands of them. They are a major cause of allergies and asthma attacks, though they are often overlooked as the culprit. Memory foam mattresses cannot house dust mites because they are densely cell-packed, making it so there is no space for a dust mite to live.
Although memory foam mattresses may tend to be expensive, they last a very long time, meaning that you will spend the same amount or even less over a twenty-year period on mattresses if you choose to go the memory foam rout. Ordinary innerspring mattresses become dirty and misshaped over time, so they must be replaced every five years. But memory foam mattresses last about twenty years.
