Sleep Better with a Memory Foam Mattress Pad

When trying to sleep better with memory foam mattress pad some people may find that it is too soft. Before making a decision to purchase, here are some facts about what makes visco memory foam mattress pads appear soft, therefore questioning the quality of the product.

Most people believe that a visco elastic memory foam mattress pad is heat-sensitive as a result softens at body temperature. Visco elastic foam does respond to temperature because they are viscous (harder) when cooler and elastic (softer) when hotter. But the temperature ranges, in which the memory foam reacts, is much more extensive than what the body can give off.

There are two types of viscofoam; viscoelastic memory foam that reacts to temperatures at a much higher or lower range of temperature and viscoelastic memory foam that responds to body temperature. Both types contour to your body’s shape but the temperature-sensitive foam softens and can follow your body contour more accurately as a result distributes your weight by reducing pressure points. The heat-response visco memory foam mattress pad does all that plus feels more unique and soft to the touch.

Memory foam mattress pads that are sensitive to body temperature are more expensive, because how they are manufactured. Tempur-Pedic is one of the most expensive memory foam mattress pad on the market and is also the standard in which all other products are compared to. One of those products is the Isotonic Ultimate Memory Foam Mattress Topper with Velour Cover

The isotonic memory foam mattress topper/pad is cost effective and is extremely comfortable from its 2" 4 lb visco elastic memory foam. The twin memory foam mattress pad is roughly $120 and the queen memory foam mattress pad is about $160. Even thou the feeling of the memory foam topper is great, the mattress pad has quite a poor looking dark yellow cover. If you don’t mind that your bed looks a bit yellowish this is a great topper at an inexpensive price. One thing about the cover is its breathability which will help decrease your body temperature so you can fall asleep easy. Other covers such as those that are waterproof are not breathable making it a bit sticky. I only recommend waterproof covers for memory foam mattress pads with animals, toddlers and the elderly due to the fact that the memory foam mattress pad topper is hard to wash and it’s better to be safe than sorry.

You can purchase an isotonic memory foam mattress pad 2 inch. or a memory foam mattress pad 4 inch, these are the standard options. I only recommend the 2 inch if you have a firm mattress. The isotonic memory foam mattress pad manufacturer offers a 30 or 60 day money back guarantee.

Tempur-Pedic mattresses are not made entirely out of memory foam, because visco elastic foam is too soft to make an entire bed out of it. They are a leading brand because they react to body temperature and soften only at the top while others are softer throughout due to being responsive to room temperature. Warning: if the room temperature is high a less temperature-sensitive bed can become even softer and lose cushioning therefore become uncomfortable where as Temper-Pedic beds retain their firmness.

For memory foam mattress pad to be visco-elastic it has to be temperature sensitive with the ability to rebound quickly and return to its normal shape. A memory foam mattress pad review by its viscoelastic makeup and its durability by breaking it down into the following grading system:

1. Weight (Density in pounds per square foot):

- The weight of foam is determined by the amount of chemicals used in the composition of the polyurethane foam. The more chemicals, the higher the density and the more visco-elastic it will become. This density will not determine the hardness of the material; this is done through utilizing the ILD rating structure. Many memory foam mattresses use a 4 and 5lb. density, but some use as low as 2 and 3lb. densities.

2. ILD Rating (Indentation Load Deflection):

- The ILD rating is going to tell you how hard or soft a material is. The 25% ILD rating is the number of pounds required to achieve a 25% compression of a 4? thick foam using a 50 square inch indentation. An Example of this is as follows: 20lb. ILD foam indicates that this material took 20 lbs. of pressure to indent this foam 25%. Keep in mind that the higher the ILD, the firmer the foam.

3. Resilience:

- This measures the foam’s springiness by determining the percent rebound of a steel ball dropped from a height of 36. The term “H.R” foam refers to a highly resilient foam that will give a very high “ball rebound” reading. In general, the higher the resiliency, the better the more durable the foam will be with compression forces.

4. Tensile:

- This indicates the extent to which foam can be stretched, measured in pounds per square inch, and how much elongation in terms of percent of stretch before rupture. This value has little relevance to memory foam mattresses because they are not usually stretched, and will become compressed only when slept on.

- It is important to remember that these ratings can vary from each foam batch that is poured and that no mattress company can predict an exact rating on their mattress each time they produce the final product. As an example, a 10 ILD rated foam could vary from 8 - 12 ILD each time the foam is poured. Especially check the ILD with each product and if purchasing from non merchants such as eBay. A lower ILD might be the reason for the memory foam mattress pad sale comparing it to other products size is not enough.

The manufacture also has a warning label on the memory foam mattress pad, it states:

[caption id="attachment_1134" align="alignright" width="242" caption="Sleep Better with a Memory Foam Mattress Pad"][/caption]

WARNING: URETHANE FOAM IS FLAMMABLE. The urethane foam mattress pad label clearly states do not expose urethane foam to open flames or any other direct or indirect high temperature ignition sources such as burning operations, welding, burning cigarettes, space heaters or naked lights. Once ignited, urethane foam will burn rapidly, releasing great heat and consuming oxygen at a high rate. In an enclosed space, the resulting deficiency of oxygen will present a danger of suffocation to occupants. Hazardous gases released by the burning foam can be incapacitating or fatal to human beings if inhaled in sufficient quantities. This may be a good reason to not use a memory foam mattress pad for an infant or anyone that is incapacitated. A memory foam infant warning : it is not recommended for a baby that cannot lift their head, due to the the memory foam being heat-sensitive there is a chance they can smother.
