Memory Foam Mattresses

Memory Foam:

Memory Foam

Memory Foam was developed by NASA during the 1960’s.  In the late 80’s/early 90’s, a Swedish firm, Fagerdala World Foams (that would go on to become Tempur-Pedic) was the first to think outside the box and recognize the commercial possibilities of Memory Foam as a mattress material.  Tempur-Pedic is still the best known in this category and leads the high end market, but many other brands have moved in providing other options to choose from, including a new movement into the ‘green’ or ‘eco-friendly’ market.  Memory Foams are also being used for mattress toppers and pillows.

Memory Foam Characteristics:

Memory Foam has the unique ability to mold itself and support the sleepers body.  A durable polyurethane based foam is filled with millions of miniscule air pockets that decompress with the weight and heat of the sleepers body.  The sleeper sinks in to the mattress, creating a floating sensation.  Higher density foam provides more support while lower density foam allows you to ‘sink’ into the mattress more.  A thicker mattress allows the sleeper to sink further as well.

Memory Foam Molding Characteristics

Memory foam’s density is measured pounds per cubic foot, and a most memory foam has a density between 1 and 5 lbs/cf, with 5 being considered of higher quality.  Memory foam mattresses are generally comprised of several layers with varying densities to help support and distribute a sleepers weight.

Memory foam is an excellent choice for sleepers who like to feel snug and like the sensation of sinking in to their mattress.  It is also ideal for those sleepers who don’t move too much (toss and turn) and/or don’t want to be awakened by a partner who moves around.  You will receive a feeling like you are floating.  These mattresses are also hypoallergenic, making them a good choice for consumers with  or who are susceptible to allergies.  A well made memory foam mattress can be expected to last 10 to 20 years.
