Numerous studies show that quality sleep lays the foundation for good health. Considering that the average person spends 30 years of their life slumbering in bed, it’s no wonder consumers are on a quest for the perfect mattress – one that relieves pressure, eases joint pain and promotes a blissful state of relaxation. The industry has responded with a dizzying array of mattress components, technologies and materials, perhaps none more groundbreaking than visco-elastic memory foam. Originally developed by NASA engineers, memory foam proved a major departure from traditional bedding materials in that it was temperature sensitive and could mold to any shape or form.

What makes memory foam mattresses unique
Memory foam is ingenious because it can change shape slowly and then flex back to its original form once force has been removed. In the context of sleep surfaces, this is a pivotal difference from traditional innerspring beds that remain mostly rigid under body weight, allowing pressure points to mount while restricting circulation. By contrast, a memory foam mattress selectively disperses pressure along the length of the body and bed surface, while conforming to the curves of the shoulders, hips, knees and spine. This even weight distribution yields excellent pressure relief, particularly for side sleepers. Once liberated from the disruption of repeated tossing and turning, sleepers can more effectively restore their bodies with deep, REM slumber.
Pros and cons of memory foam
Like all mattress materials, memory foam has both its advantages and drawbacks. In the realm of health benefits, visco-elastic memory foam is praised for its ability to promote proper spinal alignment, and allowing greater cushioning across the body. The viscous material softens in response to heat and gradually creates a cradle-like effect. Another pro is memory foam’s ability to absorb energy rapidly, thus reducing the amount of vibration transfer across the bed. This superior motion isolation is great for those who are easily awakened by a restless partner. Anecdotal evidence suggests that “body-conforming” materials like memory foam have a positive effect on blood flow, while preventing the onset of lower back and joint pain. On top of that, memory foam is incredibly durable and will easily outlast your typical innerspring bed. Even the lower-priced models will last a good 8 to 10 years.
Perhaps one of the biggest concerns about memory foam is its tendency to trap heat and “sleep hot.” Earlier mattress prototypes certainly fit this description, but newer sleep technology has taken heat retention out of the equation entirely. Now, consumers can find a slew of high quality memory foam beds with gel materials that maintain a cool sleeping surface.
How much does a memory foam mattress cost?
Memory foam mattresses have gained traction for good reason: they offer great value and are priced to accommodate all budget levels. Price points generally depend on foam density and the type of foundation and comfort layers used. When looking for the ultimate blend of comfort, durability and support in a memory foam bed, you don’t have to spend a fortune. According to Consumer Reports, price isn’t a reliable gauge of mattress quality and comfort, considering some of the more highly rated sleep systems sell for under $1300.
In the end, buying a mattress is a highly personal decision, and memory foam is just one of several tempting options.
