When looking for a memory foam mattress near San Francisco, it is best
to start with an understanding of what makes this
type of mattress worth the investment. This article will take a closer look at how a memory
foam mattress is made to help you make a more informed purchase.
Memory Foam History
NASA first developed memory foam as a result of testing various materials
to increase astronaut safety during take off. The goal was to create a
more comfortable seat cushion that could withstand multiple g-forces of
pressure. Nearly 20 years after NASA created the material, the patent
was released to public domain. This led to the production of the Tempur-Pedic mattress.
Memory Foam Production
When chemicals are added to polyurethane, a wide variety of materials can
be made. When the right amounts of certain chemicals are added to polyurethane,
it is transformed into a mattress that has
revolutionized the way people sleep. In production, the foam expands, creating its signature open cell structure.
This structure is what causes the foam to bounce back from pressure. A
more open cell structure will allow for more airflow to optimize sleep comfort.
Memory Foam Variations
Since the cell structure within the mattress can vary depending on production,
memory foam mattresses vary in firmness. The rating of the firmness is
known as Indention Force Deflection (IFD) or Indentation Load Deflection
(ILD). The force required to make a one-inch indentation in the mattress
determines the IFD or ILD. Memory foam mattresses generally range between
one and seven pounds; when searching for a quality memory foam mattress,
you will want to aim for four or five pounds.
