We've talked a little bit about memory foam mattress within our discussion on visco elastic. As we discussed there, it is simply polyurethane with a couple of additives to enhance it's density and viscosity. It makes sense a foam that's firm, but gives when weight is applied. If you have sat with an airplane, or squeezed the headrest in a recent-model car, you've felt what memory foam feels like. It is a material that's unlike most others and it has a feeling that's hard to describe. But, those who sleep on it each night recommend its ability to comply with the body, decrease being restless, and promote an overall better night's sleep.

So, if foam is so great, the ones enjoy sleeping on it so much, then why is there a market for memory foam mattress pad, and why are you looking over this post? Well, as I'm sure you might know, these things are expensive. Originally designed by NASA for airplane seats, these components actually only became available to the general public market in the early 1980s, and just actually became affordable to the general public sector about ten years later. Starting in the early 1990s, the marketplace for memory foam began to boom. Manufacturers of all things from mattresses, to seat cushions, to pool floats began tinkering with this material to see if they might create better products. Unfortunately, though the material became available, and fewer expensive, it's remained to this day very expensive.

Now, that may happen to be an extended winded introduction, however the real reason an industry for a memory memory foam mattress pad topper emerged happens because the price of making an entire mattress out of the stuff continues to be very costly. These cost more than $1,000 and may approach prices of $3,000 and much more. The advantages, as mentioned above, have long been touted by admirers. Users claim that they can sleep during the night with ease after switching to memory foam due to a number of reasons. The foam is engineered in such a way it gives based on just how much pressure is used, and it only gives in the one local area. So, the mattress will sink in more where your hips rest than your feet since the mid-section individuals body is much heavier. This enables the sleeper to achieve an appearance position that's more natural that other mattresses allow, or so the proponents.

But can an isotonic memory foam mattress pad provide the same benefits as a full scale mattress. You might not think so, but studies have shown that these pads can indeed nearly duplicate the effect of getting a memory foam mattress, simply by being placed upon a typical mattress. Pretty good, right? When you look at the price differential -- a queen memory foam mattress pad, for example, will cost around $200, the argument becomes very intriguing.
