Memory mattress pads:

Serta Ultimate 4 inch Memory Foam Mattress Topper
Originally designed in 1966 under contract by NASA, memory foam was intended to provide better support and comfort to space shuttle seats.  The hope was that it would provide better comfort for astronauts as they experienced extreme G-Forces, as well as give them a better chance of surviving in the event of an unexpected accident.  Although it was never actually used in space shuttles, the technology was eventually released to the public by NASA in the late 1980s.  Because the material was so difficult to work with, it was not used until a Swedish company released the first Tempurpedic Mattress in 1992.  

Benefits of a memory foam ultra mattress topper:

If you find that your current mattress is causing you back, neck or shoulder pain, it may be a result of the pressure points that traditional spring mattresses create under your joints.  Although it can be quite expensive to buy a tempur pedic mattress, buying a memory foam ultra mattress topper can be an effective way to get many of the benefits of a memory foam mattress without spending a fortune.  Because of the closed cell structure of memory foam, an memory foam mattress topper will contour to the unique shape of your body, while still supporting it.  The feeling of sleeping on memory foam is unique in that it feels both soft and firm at the same time.  The mattress “gives” in areas that normally cause discomfort, but overall they feel strong and dense.  

Types of memory foam ultra mattress toppers:

There are a number of memory foam mattress toppers available, and choosing one that best fits your sleeping habits can be a difficult process.  However there are a few metrics by which you can compare all of the mattress topper options out there:

Price - More often than not, you are looking to purchase a memory foam ultra mattress topper
because they save you money compared to buying a brand new mattress.  However, you can still expect to pay a few hundred dollars for a quality mattress topper.  Don’t be fooled by low cost “foam” mattresses.  If it doesn’t have the Tempurpedic name, or say that it’s made with viscoelastic memory foam, then you are not getting a true ultra mattress topper.  

Thickness - Memory foam mattress toppers can range in thickness from 1 inch to over 12 inches.  Experts recommend at least 4 inches to receive the pressure relieving benefits of memory foam.  Obviously the more you have to spend, the thicker the mattress. Items like the Foamex 12 Inch Ultra-Lux Memory Foam Mattress Topper can be almost as good as buying a new mattress itself.  

Density - Although many manufacturers don’t publish the density of their memory foam, it is measured in pounds.  Mattress toppers can range from 2 pound density to 6 pounds, but most people will be satisfied with any mattress pad that meets or exceeds 4 pounds.  

Purchasing a memory foam ultra mattress topper can be a great way to save money, and get a good nights sleep without all of the hassles of buying new furniture and disposing of the old mattress.  If you are looking for great deals on memory foam mattress pads, authority sites like have special savings available regularly, although you can also find great specials at places like Sam’s Club or Costco.
