The two basic types of latex mattresses are made either from the sap of the rubber tree or synthetically with petrochemicals. Sometimes the two substances also are blended, often to save money, since a natural latex foam mattress is very expensive. The blending might also be done because natural latex can be less comfortable, so manufacturers try adding some of the properties that petrochemicals provide. Yet a natural latex mattress can be made more comfortable by infusing natural oils and plant extracts, so natural vs. chemical doesn’t need to be a deciding factor when it comes to comfort.

A latex mattress is created in one of two ways. With the Standard method, the rubber sap is whipped into a froth, to fill it with the air bubbles that give memory foam its unique characteristics. After the whipped substance is sealed in a mold, it’s heated and cured into finished form. The Talalay method adds thousands of pin-like spikes to the mold, creating channels for the air bubbles and making the final latex foam mattresses more buoyant and resilient. Both of these processes can use blended foam, though, so you’ll need to investigate further if you’re concerned about eco-friendly mattresses.

Nor is every latex mattress necessarily organic, so that will be the main certification to check out. If a mattress is simply labeled “natural” or “green,” it may still contain some synthetic materials. Having actual “organic” certification, however, should mean that all materials used will be completely natural, and chemical and pesticide-free.

You must be sure to do all the research required before you buy a new mattress. Even labels that appear to meet your own high ecological standards might be “fudging” the facts a little, where supposedly “green” products still contain petrochemicals. And foreign manufacturers might not be as reliable as you had hoped. If you find out all the information you can about latex mattresses and memory foam mattresses before you head out on your shopping expedition, then you should be able to make a much more informed choice, with all the facts at your disposal.

Before looking at any memory foam mattress toppers or pads, do some research. To begin with, you need to be sure that your own original bed is in good enough shape to accommodate a memory foam mattress pad or topper. Your underlying mattress needs to be of moderate firmness (neither too soft nor too hard) and above all it must be very flat, with no dips in it and no “hammock” in the center. This is important because of the properties inherent in the visco memory foam of the topper itself.

What makes memory foam work as well as it does is because of the millions of tiny cells that soften with your body heat and gradually change shape to conform to your own contours. In a standard memory foam mattress, the heat only extends down about 3 inches, so that the underlying layer remains firm, in its original shape, providing support. This is why you need a firm, uniform underlying mattress if you are going to put a memory foam topper over your existing mattress. But it also means that if you buy a mattress topper from 3 to 5 inches in thickness, you’ll experience the effect of a full memory foam bed. Keep in mind, though, that if you go over 4 inches or so, the expense will start adding up almost to the full cost of a complete bed.

Buying a mattress topper of memory foam should allow you to experience most of the benefits of a full bed, provided you take heed of all these important factors. If you’ve got a flat, firm underlying mattress, combined with a topper of good thickness (not to mention the density, which should be about 5 pounds per cubic foot of mattress), then you should be able to enjoy the gentle contouring of the foam mattress enhancer, along with good underlying support.

How was memory foam mattresses invented?
Believe it or not but memory foam mattresses were not initially even designed to be mattresses. It is the memory foam that was created first. This revolutionary material was designed by NASA in the 1970’s for use in the space program. The idea was to create foam that would help astronauts when they experienced the high G’s of liftoff. The cushion would help protect them from the pressure. Unfortunately the foam did not make it into the shuttle or into the space program. But the medical community quickly saw the advantages of this foam to help patients that were suffering from bedsores. The initial concepts of a memory foam mattress were not truly developed and expanded upon until the Swedish company Tempur-Pedic got their hands on the foam. They were able to design a mattress that was not brittle and would last far longer than the earlier attempts.

Does it take time for people to adjust to sleeping on memory foam mattresses?
Memory foam mattresses are definitely not like traditional bedspring/pillow top mattress sets. You definitely have to get used to sleeping on this foam. At first it is going to feel really strange because the foam basically holds to your shape. It may feel like it is clinging to you. Another factor in why it takes people time to adjust to their memory foam mattress is the heat difference. The foam does give off more heat and holds more heat in. It will take a few weeks for your body to adjust to this heat.

Do memory foam mattresses resists stains better than contemporary mattress sets?

Unfortunately no, they do not resist stains better. You have to stop and think about what type of material the mattress is made from. Most traditional mattresses have a slick, almost satin-like, top that will repel some spills and stains. Memory foam mattresses are made from foam which will soak up a stain like a sponge. Most people do not have to worry about stains but if you are buying a memory foam mattress for a toddler that is not fully potty trained yet, you may be buying the wrong mattress. These are very expensive mattresses and you do not want one soaked with urine. Granted there are ways around the stain issue. One way is to put down a barrier sheet that will protect against stains. Another is not to try the wine glass trick. You know…the one where someone is jumping right next to a glass of red wine to prove that the memory foam mattress is so stable.

What is the average price for memory foam mattresses?
Ah, now this is where it gets tricky. The price for a memory foam mattress varies depending on what manufacturer you buy it from. The weight per cubic foot plays a tremendous factor. If you go with an off brand of memory foam mattress you may pay a thousand and some odd dollars for the product. If you go with a Tempur-Pedic memory foam mattress you are looking at several thousand dollars. Also bed size plays a factor. Obviously the larger the mattress the more you are going to pay for it. This is one area where you definitely need to shop around to get the best bargain but still get a mattress that works well for you.

There are two processes used to create latex mattresses. With the Standard method, the liquid (whether it’s the rubber sap or the petrochemical substance) is whipped into a froth, which creates the millions of air bubbles that are responsible for the special properties of a foam mattress. Then the liquid is poured into a mold, which is sealed and heated until it cures into its finished mattress form. In the Talalay method, the mold contains countless tiny pinprick spikes that make extra little channels for air to move through. This method creates a latex foam mattress that’s somewhat more resilient and buoyant.

Given that natural latex works just as well with either process, you might reasonably wonder why a latex mattress would ever be made with petrochemicals. The difficulty with natural latex is that the mattresses can turn out to be less comfortable. This is why a foam bed is often made entirely with synthetic latex. Or frequently, a manufacturer might use mostly natural latex and blend in some of the petrochemical version, just enough to add the extra give and softness that people want. So latex mattresses can be made of natural or synthetic materials, or a blend of both.

It’s absolutely essential to do your research before buying a latex mattress. If it is comfort that you are looking for, then this does not mean you’re stuck with only synthetic latex choices, as an infusion of natural oils can now make natural latex just as comfortable. Yet even a “green” label might hide the fact that your foam bed still contains synthetic materials. This is why you’d do well to read about mattress manufacturers, their products, and what processes and materials have been used. Be informed with these mattress tips and more, and have all the facts at your disposal before you head out mattress shopping.

Before deciding that, you may want a quick primer on what natural latex mattresses are actually made of. This latex is a substance that’s derived from the sap of rubber trees. In 100% natural latex, the thick liquid is frothy or otherwise infused with tiny air bubbles, a process that creates the unique foam mattress properties of this type of bed. Other kinds of latex, however, while using a similar process, are synthetic instead, made with petrochemicals. A third, blended type of latex foam mattresses uses a mix of natural and petrochemical latex to reduce costs. An all-natural latex mattress can be very expensive, which is why the latter two kinds are so popular.

In the end, you may still not mind the higher cost when you consider other things. For example, natural latex mattresses simply last longer because natural latex is more durable than the other kinds. So you won’t be spending money on another foam bed for many years to come. Add to this the fact that natural latex can be just as comfortable as a 2, 3 or 4 inch memory foam mattress, when natural oils are infused and the right process is used. And this type of foam bed does not produce the unhealthy smells from off-gassing that a latex mattress does when it contains petrochemicals.

So the question may not be as either/or as you initially felt. If you want to experience the benefits of a foam bed, yet don’t want something derived from ecology-damaging petrochemicals, then one of the natural latex mattresses may be what you’re looking for. And if you’re still worried about the cost, then remember that you make other investments in your future well being, as in your vehicle or your home. If you think of this latex foam mattress as another such investment, you may decide that the cost is worth it.

Visco elastic memory foam is comprised of tiny, spherical, weight and temperature sensitive cells. As the cells heat up, they soften and spread pressure, which means that as you lie down on a memory foam mattress, your body heat makes the initially firm substance of the foam relax and conform to your own shape. Once your heat is removed, the tiny cells firm up again and return to their original shape. This, as you might imagine, is where memory foam gets its name.

There’s more to the support than that, though. The visco memory foam only heats up and becomes elastic down to a certain depth. So the top layers of cells will soften and adapt to your body shape, yet the foam farther down remains as cool as before, and therefore doesn’t change. So it retains its shape and provides extra underlying firmness, meaning that memory foam mattresses give you both the contoured support above and the firm support below.

Another factor in both the support and the shape of the mattress is its own density. You might find inexpensive memory foam mattresses with a density of 1.5 pounds per cubic foot, and another of 8 pounds. A higher density will provide more support and relief for those with hip or back problems. Additionally, there are single, double, queen or king size memory foam mattress choices available, as well as memory foam contour pillows.

What all of this information means, in the end, is that even the pressure points of the body that push harder into a mattress than other points do (things like hips, for example) are relieved on a memory foam mattress. Since the entire body is supported equally, this can help those with arthritis and even bedsores. A memory foam bed might be just the thing you’re looking for if you want to sleep without getting stiff and sore.
