Natural versus Synthetic Latex

DIFFERENCE BETWEEN NATURAL AND SYNTHETIC LATEX

Many people are perplexed to learn that not all latex is created equal. There is a natural form of latex and synthetic.  As a matter of fact, there is a world of difference between natural latex and synthetic latex.

Natural latex is manufactured from sap tapped from rubber trees, then it is either vulcanized (Dunlop method) or frozen, then vulcanized (Talalay method.) I don’t want to get too involved in which method is better, because it’s hugely dependent upon the processing facility and a number of other factors.

The point is, natural latex is an incredibly resilient and durable, clean and supportive material. It is resistant to dust mites, anti-microbial, antifungal, and hypo-allergenic.

The important thing to remember when considering a product made of natural latex is purity – what is the percentage of pure natural latex vs fillers or synthetic material. Look for certification by an independent laboratory such as Oeko-Tex, which tests for chemicals and toxins in the finished product. The Oeko-Tex stamp of approval will attest to the cleanliness and purity of the product.

Some manufacturers add fillers (most commonly clays, calcium oxide, or titanium dioxide) to the natural latex to make it go further (imagine taking one gallon of milk and diluting it with water to create two gallons of milk). While the finished product will be less expensive, the addition of fillers ultimately makes the latex less durable and more apt to rapid breakdown. Here’s where the consumer needs to be very vigilant…the fact is that natural latex with additives such as those listed above can technically still be called “natural latex”.

Synthetic latex (aka polyurethane foam/memory foam) is made of petroleum by-products, sometimes actually mixed with natural latex.

Again, that’s where you have to be careful. There are many manufacturers who tout their product as “natural latex”, when in fact it’s actually a blend of natural AND synthetic. Interestingly, Dunlop and Talalay latex can be either natural or synthetic. Needless to say, Caveat emptor — do your research.

Synthetic latex, being chemically based, has a tendency to break down more quickly than natural latex. If you’ve ever had a warranty issue with a mattress, you’ll understand immediately. Have you ever had a body impression in your mattress measured by your friendly local mattress salesman and told that it’s “normal wear and tear?”

What You Need to Know Before Buying a Latex Mattress

What You Need to Know Before Buying a Latex Mattress

If you’re interested in buying natural latex mattresses but don’t exactly know where to start, here is the basic information you’ll need to know.

It’s Not Pure Latex

Even if someone sells a mattress as “100% latex” it’s not technically true. The natural sap from the rubber tree has to be processed in order to be able to form latex layers or cores for the mattress. If the sap was processed at 100%, it would be to thick to form the natural layers in the beds. The manufacturing process involves adding a few minor additives which is why the actual percentage is between 95-97% latex. Many bedding companies use blended latex, where they use only 5% of natural latex and the remaining is petroleum based foam. In the process they increase the margins and profits by misleading you the customer.

If you’re in the market for truly natural rubber then the less than 5% that isn’t latex should have no bearing on the comfort or quality of the mattress when you compare it with synthetic or blended foams.

How Long Will it Last?

This depends on the manufacturer but natural latex mattresses have a considerably long life. If you buy high-qualitynatural latex mattresses and take care of it you could have the mattress for up to 30 years and still get a good night’s rest. The average traditional coil spring mattress usually lasts six to ten years. So at the end of the day, any additional cost or hassle associated with a latex mattress is well worth it considering how much longer they last.

Rubber Isn’t Easy to Get

You might think that because the sap from the rubber tree comes from a tree that it’s simple to process but rubber trees only grow within 10 degrees of the equator, making the supply rather limited. Another limitation on harvesting rubber is the weather. Rubber trees can only be sliced during the dry season – which only adds up to 180 days out of the year.

How Rubber is Harvested

The rubber tree is sliced at an angle, about three feet long, allowing the serum to run into a holding container. After an hour or so the serum stops flowing and the tree eventually heals. It’s interesting to note, when the serum is harvested more than half of it is water.

About LatexHow Latex Rubber is Processed

In order to prevent the serum from coagulating before it can be processed most companies add ammonia, which eventually washes out as it is processed. The rubber serum is then whipped in a centrifuge to separate the elements and concentrate the rubber to be used. The final step involves washing the latex through water and squeezing the excess out using metal rollers.

Pros to Sleeping on Latex

Most foam mattresses “sleep hot” which means they absorb your body heat while you sleep, making you warmer. A latex mattress allows air to circulate which creates a cooler and more comfortable sleeping arrangement and the night’s sleep you’ve been looking for. Traditional mattresses will sag with use and time but because of the resilient material, latex mattresses are less prone to sagging providing you with a better night’s sleep. Latex mattresses are also great for relief on your pressure points while providing enough support for your back and joints. Because the latex material absorbs motion it makes it the ideal mattress for sharing. This way, everyone has uninterrupted sleep.

Rossa Foundation Requirements

The Rossa mattress requires a unique foundation. The coil springs used in most supporting box springs are approximately 3 inches in diameter. The diameter of coils used in the Rossa mattress is approximately 1.5 inches. What this means, is that to prevent the pocket coils from resting on an unsupported space, one of the following options must be used:

  • Order the Rossa with the coordinating OMI foundation, which is padded to offer the coils proper support.
  • Order the Rossa with the supplemental foundation layer. The supplemental foundation layer can then be placed on top of a supportive platform bed, box spring, or foundation.
  • Place on a slat bed frame with no more than 1 inch between slats (most platform bed frames have 2-3 inch space between slats)

Not using proper support could void the warranty
