Related to Sleep Disorders Memory Foam: Pros and Cons Considering a memory foam mattress or similar product? Read what sleep experts say about it. Few things feel as good as a good night's sleep. That's especially true if sleep seems to escape you, night after night after night. If you've heard about memory foam, you may wonder if it could improve the quality of yoursleep. Some people swear by it. Others are less enthusiastic. What exactly is memory foam? And what are its pros and cons? Here's information to help you decide whether memory foam is worth a try. What Is Memory Foam? First designed in the mid-1960s for NASA airplane seats, memory foam is made from a substance called viscoelastic. It is both highly energy absorbent and soft. Memory foam molds to the body in response to heat and pressure, evenly distributing body weight. It then returns to its original shape once you remove the pressure. In addition to protecting against impact, these properties make memory foam very comfortable.
After its "virgin flight" for NASA, memory foam made a foray into other applications. For example, it was used as cushioning in helmets and shoes. Medicine found a use for it in prosthetics and products to prevent pressure ulcers such as seating pads for people who are severely disabled. Then, memory foam really took off. It's now well known for its use in pillows, mattress pads, and mattresses, which come in different densities and depths. What Are the Benefits of Memory Foam? Could the special properties of memory foam enhance your sleep? Sleep specialist Donna L. Arand, PhD, says that objective studies supporting the claimed benefits of memory foam -- or the effects of any particular type of sleeping surface -- are lacking. This is true for a variety of reasons, she says. This type of sleep study can be expensive, if conducted independently. Or it is "chased" by a shadow of bias, if supported by industry. Also, some sleep technology, such as memory foam, is relatively new, so it hasn't been well studied.
But perhaps one of the more difficult stumbling blocks to testing the health benefits of mattresses such as memory foam is the subjective nature of sleep. It is simply difficult to measure. Sometimes the brain's electrical activity, measured with an electroencephalogram (EEG), and other findings recorded during a sleep test don't always match up perfectly with a person's subjective experience, says Arand, who is the clinical director of the Kettering Sleep Disorders Center in Dayton, Ohio. "They might say, ‘I had a great night's sleep,' but the EEG parameters might not really indicate that." Sleep is not only subjective, but preferences for sleep surfaces are individual, Arand says. "There's quite a bit of variability between individuals in terms of what type of surface -- whether it's firm, hard, or soft -- they prefer when they're sleeping," she says. "As far as we know, there is no rhyme or reason for that." Many of Arand's patients who use memory foam have offered unsolicited glowing reports like these about memory foam: "I'm sleeping great."
"Best sleep I've ever had." "I love going to bed at night." Arand says these anecdotal responses may be one-sided. That's because she and other staff don't ask all their patients about their sleep surfaces. "We may only be hearing the good stuff," Arand says. Kathy R. Gromer, MD, sleep specialist with the Minnesota Sleep Institute in Minneapolis, agrees that memory foam may improve sleep. "It can, if it relieves painful pressure points," she says. But Gromer adds that memory foam doesn't do anything for sleep apnea or other sleep-breathing disorders -- and sleep disorders are the primary complaint of most her patients. "When you lie on the memory foam, the heat from your body softens it in appropriate points," Arand says, "so this helps to support your body along the curves and natural lines of the body." Memory foam manufacturers claim this helps relieve pain and thereby promotes more restful sleep. And, though consumers often believe that very firm mattresses are best, more "giving" mattresses like these may lead to better sleep in people with back pain, according to the National Sleep Foundation.
Although there aren't scientific data to support the hypothesis, Arand wonders whether memory foam sleep surfaces might be especially helpful for older people. For them, minimizing extra movement could reduce the number of times they awaken during the night. Being less aware of a bed partner's movements might be an extra benefit, she adds. "Without the coiled springs, you feel your sleep partner's movement less, and that might help, too." What Are the Disadvantages of Memory Foam? Gromer says that memory foam products may retain body heat, which could make them less comfortable in warm weather. However, Arand has not heard this complaint from her patients. "In our culture, most people can adjust their thermostats or blankets for the appropriate season," Arand says. When new, memory foam can produce an odd chemical smell -- a phenomenon called offgassing. To minimize this problem, the Sleep Products Safety Council, a sleep products trade group, recommends airing out the mattress or pad for at least 24 hours before putting sheets on it.
"If you follow directions, the smell dissipates quickly," Arand says, "But I've never heard of anyone having reactions to it." Are Memory Foam Products Safe for Young Children? "I would strongly recommend avoiding this and similar very soft materials for use in infants' beds," Gromer says. "That's because soft bedding traps [carbon dioxide] and increases the risk of sudden infant death syndrome (SIDS) deaths."What It Is, Why It Works, And The 5 Key Things To Look For When Buying A Memory Foam Bed Or Topper. While memory foam was developed for NASA in the 1970's, it didn't hit the consumer market until the early 1990's - first as memory foam mattress topper pads, and later used in memory foam mattresses. Since then, memory foam mattresses have become the fastest growing segment in the mattress industry. With every year, you see more and more companies selling memory foam mattresses and topper pads, and it is very difficult, even for those of us in the industry, to keep up with all the new memory foam products being introduced.
What is a consumer to do? 1. Brief History Of Memory Foam And Why Not All Memory Foam Created Equal - Some Just More Comfortable And Sleeps Cooler Than Others 2. How To Choose Between Different Memory Foams 3. What To Look For In A Memory Foam Mattress Or Topper, And When You Might Need To Get A New Mattress In this guide, I'm going to do my best to give you the straight story on what memory foam is, how it works, and what to look for in memory foam (density and quality, memory foam toppers versus memory foam mattresses, etc.). Armed with the information, I hope you are able to find just the right memory foam mattress, topper pad, or other product that fits your needs. Where the mattress industry so often sells on hype about latest greatest technology, I wanted to concentrate on actual, verifiable information when putting together this guide. So before we go into the details about memory foam, I thought it was important to first look at the bottom line -- how does memory foam compare to standard innerspring mattresses for comfort.
And what is great about the internet is that these days you can cut through the hype to see the actual data on this -- real reviews, by real folks, trying out the mattresses in their own homes. And while it was hard to get this kind of objective information back in '94 when I was first starting out selling memory foam after it helped me with my back pain, in 2014 all this information is now at your fingertips, literally. While comfort is subjective, what is no longer subjective is that certain types of mattress are just more comfortable than others. And you don't have to take my word for it, or any other mattress retailer. The numbers don't lie. Based on over 22,000 real people's mattress experiences, the meta site Sleep Like the Dead found that in analyzing this information that memory foam mattresses received the highest level of customer satisfaction of any mattress type at 81%. In contrast, only 64% of innerspring owners said they were satisfied. That is a huge difference, and shows the simple reason why memory foam has gained such popularity -- it delivers comfort in a way that far surpasses the standard innerspring mattress.
