Memory Foam Mattresses – Better Sleep Thanks to NASA
When astronauts lift off, it takes an incredible amount of force to launch them out of the Earth’s atmosphere. Without proper gear, the body can’t withstand this force, so NASA sought to create a material that could cushion the impact for astronauts. The result: memory foam. This revolutionary product created a pressure-free place for the astronauts during lift-off. NASA’s innovation is good news for you too. Now everyone can have the benefit of pressure-less mattresses without leaving Earth.
Memory foam mattresses are made of “open celled” material - air is allowed to travel between the cells. When you lie down, the material compresses, relieving pressure on the joints. It creates a feeling that you are floating, and you spend far less time tossing and turning. Another reason why these mattresses are so popular is that they are sensitive to your temperature. After you have been on memory foam for a few moments, it softens where the most amount of pressure is. You feel like the mattress has just melted into you, creating even greater comfort. This is a mattress that responds to your needs and does not force your body to adjust to it. Memory foam also reduces dust mites and allergens by up to ninety percent, which helps reduce asthma and allergy symptoms. The memory foam mattress is the most popular alternative to those with innersprings – so among all choices, how can you be sure you are getting the best mattress for the best night’s sleep?
Density matters. Experts say that to get the best comfort and the advantages of memory foam, you need a density of between 5.3 and 5.9. (Density refers to how much one cubed foot of that particular foam weighs). If it is higher, it will not respond as well to your body. If it is lower, it is mostly air. Lower density foams are more air than foam and do not provide support or relieve pressure as the high quality foams do. Make sure that the mattress you purchase has at least three inches of memory foam on the top layer. If it offers less, then you will not be given pressure-less sleep. It is worth paying a bit more for higher quality because you will not have to replace the mattress as soon and you will have far better sleep quality. When shopping for a memory foam mattress, make sure to look for models with a twenty year warranty – this ensures the best quality. Also, don’t be afraid to test out every one! It needs to feel right to you and meet your body’s needs
