Memory foam may help sleep, according to Kathy R. Gromer, MD, a sleep specialist at the Minnesota Sleep Institute in Minneapolis. “It could,” she replies, “if it reduces painful pressure points.” But, according to Gromer, memory foam offers nothing to help with sleep apnea or other sleep-breathing abnormalities – and sleep disorders are the most common complaint among her patients.
“When you lie on the memory foam, the heat from your body softens it at appropriate spots, so this helps to support your body following the curves and natural lines of the body,” Arand adds. According to memory foam makers, this helps reduce discomfort and promotes more peaceful sleep. And, contrary to popular belief, more “giving” mattresses like these may lead to improved sleep in persons with back discomfort, according to the National Sleep Foundation.
Although there is no scientific evidence to support the theory, Arand speculates that memory foam sleep surfaces may be especially beneficial for the elderly. Minimizing unnecessary movement may lessen the number of times they awaken during the night. She adds that being less aware of a bed partner’s movements may be an added benefit. “Without the coiled springs, you feel your sleeping partner’s movement less, which may also assist.”
What Are the Drawbacks of Memory Foam?
According to Gromer, memory foam products may retain body heat, making them less comfortable in hot weather. On the other hand, Arand has not heard this concern from any of her patients. “Most people in our society can alter their thermostats or blankets for the proper season,” Arand explains.
Memory foam can emit an unusual chemical odor when new, a phenomenon known as off-gassing. The Sleep Products Safety Council, a sleep products trade group, recommends drying out the mattress or pad for at least 24 hours before putting sheets on it to minimize this problem. “If you follow the guidelines, the scent goes away soon,” Arand explains, “but I’ve never heard of anyone having an allergic reaction to it.”
Are Memory Foam Products Safe for Toddlers?
“I would highly advise against using this and comparable very soft fabrics in infants’ mattresses,” Gromer explains. “This is because soft bedding retains [carbon dioxide] and raises the likelihood of SIDS deaths.”
