Looking for a new mattress can be very confusing. The salesmen go over the details of all the mattresses, having you lay on them, bounce on them, and sit on the edge to demonstrate all the features. By the time, you try them all out; you have forgotten what the first one was like.

There are many sizes to choose from: King, Queen, Full, and Long. Then there are the materials the mattresses are actually made of from water mattresses to coils and foam. Out of all the available mattresses, the memory foam seems to be the most comfortable mattress, supporting all parts of the body. It is also guaranteed to last longer than conventional mattresses without sagging or deteriorating.

NASA developed memory foam for astronauts to relieve the enormous g-force during rocket launch, travel and entry back into the Earth's atmosphere. They constructed a breathable, high-density material that was sensitive to body temperature, and pressure. The developed foam was able to distribute body weight over the whole foam top. This feature is great for different body sizes. The memory foam will actually adjust to whatever body size or weight is on top of it, leaving no sections sagging or uncomfortable. It is very useful for a guest bedroom where different people would be using the bed. If space is a consideration, even a twin memory foam mattress will provide as much comfort to a guest as the king or queen bed he or she is accustomed to. The memory foam actually form fits to the person sleeping on it, whether on the side, back or stomach. Another added feature is that it is warm in the colder months, yet remains cool on a hot night. It is so comfortable that a restful night's sleep is inevitable.

If the memory foam mattress is for your own bed, you will not be disappointed. It is so dense, that if you or your partner is sleeping in the bed, and the other person goes to bed later, the mattress keeps its shape. Usually, the sleeping person will not even feel the other get into the bed. Even getting up to use the bathroom in the middle of the night will not disturb your partner's rest. Another issue when considering whether or not to choose a memory foam mattress is dust mites. Most mattresses are infested with the microscopic mites after a very short time. No one likes to think of these nasty little creatures, but unfortunately they cannot be avoided in a regular mattress. No matter how often you vacuum, or change the sheets, the mites will thrive. Memory foam has a natural resistance to dust mites and is hypo-allergenic. This is also a positive point if you or a family member is allergic to dust or feather products.

A memory foam mattress is a great deal considering the price of most mattresses. They are available in different depths from 2" toppers to 10" mattresses. There is a size that will fit into most budgets. Memory foam mattresses are also recommended by chiropractors for back pain relief. What works for the astronauts can work for you.
