Memory foam is a relative newcomer to the mattress game but it has quickly become a popular option for many reasons.
In the Beginning
A NASA contractor developed memory foam in 1966 in the pursuit of a better foam for aircraft cushions. By the 1980s, memory foam entered the public domain and companies began using it in medical equipment. Then came mattresses in the 1990s.
Why People Love Memory Foam
Memory foam offers a luxurious, custom comfort because of its unique features. Memory foam is temperature sensitive, making it firmer when cold and softer when warm. As your body heats the foam, it molds directly to your shape yet presses against your weight to provide consistent, full-body support.
Unlike some mattresses, memory foam contours to areas, such as your lower back, than can be pushed out of alignment by firmer beds and decreases pressure on joints, which can alleviate hip pain. Memory foam may also help lessen problems with migraines, jaw discomfort, ringing ears, breathing and tennis elbow.
As you move, memory foam slowly springs back and reshapes around your body, which makes it a great option for people who sleep in different positions. This ongoing, solid support allows your muscles to relax instead of tensing to support your body.
A Cooler Night’s Sleep
Because of its density, memory foam has a tendency to retain heat. If you tend to get too warm while you sleep, you may want to look for a gel-infused memory foam mattress that contains liquid or gel beads to help you rest cooler.
