If you are interested in mattress toppers, the comfort of memory foam one must have once or twice impressed you. Yet have you ever wondered about the origin of this material
and how it is used in the first place? Will it be surprising for you if you know that memory foam were originally invented to serve in the space industry? You can find below some facts about the story of memory foam.
1. New material of NASA
Back then in 1966, NASA wanted a new material to enhance the safety of their aircraft cushions. Basing on this request, memory foam, which is sensitive to temperature, was created. It can easily match the shape of the thing pressing against it but slowly get back to its original shape after the contact is gone.
NASA then decided to commercialize the material. By 1980s, the public had the chance to experience memory foam for the first time. Yet during this decade, the manufacture of this foam
is still difficult and the quality is not always ensured.
In 1991, memory foam was finally used in making mattress. Gradually, it has been used to make mattress pads and mattress toppers as well. From that time on, memory foam has been widely popular in this industry.
2. Memory foam mattresses’ advantages
Usually, mattresses made from memory foam have greater density than ones made from other foam. As a consequence, memory foam mattresses are firmer, heavier as well as more supportive for users. They often cost more than normal mattresses. Memory foam now has open-cell structure which can react to body temperature and pressure. When a sleeper lies onto the mattress, it quickly molds to his body’s shape and thus lessens the ordinary pressure points, reduce the sores etc…
Moreover, when the body heat increases, memory foam can react and become softer, therefore the sleeper will feel more comfortable.
Memory foam is also known for its ability to resist dust mites. Normal foam mattresses can be a good place for mites to live after several years in use, yet memory foam – composed of polyurethane – are not at all mite-friendly.
3. Some cautions against memory foam mattresses
As much as memory foam mattresses provide us with comforts, there are however some cautions that we should take on using it.
Firstly, memory foam can retain the heat of our body. Therefore, sleeping on a memory foam mattress in a hot summer night may be less comfortable than normal. Many memory foam mattresses are now produced with cooling feature to reduce this.
Besides, as memory foam is synthesized material, brand new memory foam mattresses may have some chemical odors, which are irritating to some people. Yet this problem can be solve by exposing the mattress to the air or the wind at least 24 hours before putting it into use.
It is also strongly recommended that you do not use memory foam mattresses for your babies. Memory foam mattresses can be difficult for infants to turn over; therefore there are risks of suffocation. If a baby rolls over and presses his face against the mattress, memory foam may block air passage and cause it difficult for the baby to breathe.
