Some people think that trendy memory-foam mattresses and pillows have the
ability to retain the shape of your body. In fact, the foam’s “memory property” refers
to its ability to mold to your physical contours, then return to its original shape.
As a result, the body actually sinks into a receptive cushion, thereby relieving
pressure points and permitting more even weight distribution. These mattresses are
known for providing a more comfortable sleeping experience, and less partner
disturbance from tossing and turning. First pioneered for NASA, this polyurethane
material is now available for everything from slippers and dog beds to anti-fatigue
mats and hospital beds. It is available in various types, so selection should be
made with care, as some are prone to retaining body heat and some are believed
to emit chemical odors.
