Memory Foam Mattresses
Developed by NASA during the 1970’s as a material to relieve astronauts from the pressure of g-forces while in flight, memory foam wasn’t originally intended for mattresses. It took a little ‘outside the box’ thinking by a Swedish company to realize that the potential sleep benefits of the material were too great to be ignored. With a unique ability to mold to and support your body, this material had the ability to relieve more pressure than any previous type of foam. It also takes a long time to return to its original shape – the long lasting impression of the shape of your body is what inspired its creators to coin the term ‘memory foam’.
So how does memory foam mattresses work? As opposed to innerspring mattresses, there are no separate parts. The incredibly durable polyurethane based foam is filled with billions of minuscule air pockets, which decompress when met with body weight and heat. As air releases, the person sleeping literally sinks into the bed, providing a floating sensation while balancing the body and aligning it correctly. Choosing the right thickness and density can control how much sink there is; high-density foam will provide more support, while lower density foams will allow you to sink more, and the thicker the foam, the deeper you can go. Memory foam mattresses are generally several layers of varying density that help support and distribute the sleeper’s weight.
Memory foam is perfect for sleepers who like to feel snug, and enjoy the sensation of melting into a mattress. This is also best for sleepers who don’t turn much while sleeping, or wish to curb as much movement as possible. While the foam is great at minimizing movements and the chance of disturbing a sleeping partner, that also means there is no springiness to the mattress. But for a restful sensation that feels like floating, this is the mattress to get.
