Memory foam used for beds was first engineered for the astronauts to help them withstand the G-forces when they were lifted off into space in spacecrafts. NASA developed memory foam specifically for their astronaut's comfort and safety, but it has since been developed and marketed for the general public. The material easily conforms to the body and provides dense cushioning for even the most tender pressure points. Many people find relief from arthritis, fibromyalgia and other joint or muscle problems when they sleep on a memory foam bed.
If you're interested in choosing this type of mattress, it is easy to find one that is just right for your situation. These types of mattresses can be found in all sizes from twin to king size. There are also different firmness grades so that you can select a softer or harder bed according to your preference. One thing to keep in mind when searching for the best foam mattress is the density grade of the foam. A density grade of 4 pounds per cubic foot is a good choice. Of course, it's best to personally test a mattress before making your selection if at all possible.
There are several positive features about a memory foam bed that many people find appealing:

3. Memory foam is very durable and lasts for years
4. Costs have dropped significantly in recent years so that everyone can own a foam bed

6. Provides extra comfort and back support
If you're interested in finding a good memory foam bed, there are many online distributors that offer excellent outlet prices.
