Visco Elastic Memory Foam

A Tempurpedic bed is made of open-cell memory foam. Tempur foam is made of open balloons which pass air to adjoining cells when you lie down on them. Most memory foam mattresses, in fact, are made of open cells.

Visco memory foam is as difficult to test as it is unique. There are many factors that can influence mattress performance over time, some related to the visco foam itself: heat responsiveness, firmness, recovery rate, density, resin quality, etc.

Unfortunately, reliable testing can only be done on memory foam mattress durability and not comfort which is why most visco foam mattresses have warranties against manufacturer defects and not loss of comfort.

Be warned, some foam manufacturers try to hide the low density by adding closed cells to the open-cell structure. This makes the visco memory foam seem lazy which most people associate with good quality visco memory foam. The quicker rebound of their viscoelastic foam mattress, they say, doesn't make you feel stuck in a hole where you have to roll out of. Tempur-Pedic is the manufacturer with the widest appeal.

Exposed Memoryfoam Secrets

Real NASA Link

Many memory foam mattress manufacturers claim Swedish foam was first used by the NASA Space Program to boost sales for their foam matress. NASA never did use that basic material in the 1960s. NASA foam mattress or space foam mattress technology simply does not exist as such. The truth is the Swedish Tempor-Pedic company did eventually come up with a reliable formula now used in the best-selling Temper mattress. While Temporpedic beds are commonly known as Swedish beds, not all such products made in Sweden are made of the so-called NASA bed foam.

A Temp-Pedic foam vs visco elastic foams comparison produces interesting results.

Many consumers mistakenly believe there is a difference between Tempur-Pedic mattress and visco foam mattress technology. In fact, all products made by the Lexington-based company are made of this material.

2 lb vs 3 lb density

Which to choose from a 2lb memory foam bed topper versus 3lb memory topper comparison? Higher density alone does not make a quality sleeping surface. Find out the recipe behind the best sleeping surface.

Top Tempera-Pudic Complaint

The most common problem consumers have with Temp-Pedic overlays is that they sleep hotter when compared to conventional sleeping surfaces.

But sleeping conditions are influenced by environment temperature, the material's heat sensitivity and your own body heat.
