NATURAL LATEX 5-ZONE CORE
TAKING THE GUESS WORK OUT OF PROPER SUPPORT
The concept of zoning a mattress eliminates potential problems with proper spinal alignment.
Since 70% of your body weight lies in the middle of the bed, it makes sense that the middle area should be a little firmer to offer the correct support.
If not supported properly, the heavier middle area of our body will sink deeper and further into the mattress causing disproportion.
Zoning works by providing more density (firmness) where you need it most (center of the bed). We created lateral zones which are symmetrical so the head and foot are the same, and the shoulder and lower-leg zones are the same, with the large middle section in the center third of the mattress acting as the most expansive zone. This allows easy rotation of your mattress keeping the more critical zones in-tact (shoulder area and mid-section).
Natural latex rubber is proven to be the very best component used for mattress support, comfort, durability, as well as offering a healthier sleeping environment. It's naturally dust mite resistant; it's breathable so you don't sleep hot; it's resiliency is known to last for decades; it's responsive support offers comfort most people love.
CozyPure took both of these exceptional engineering concepts to design our Pure Performance Natural Latex Core which features a 5-zone structure with a little more firmness in the center third of the mattress. Our formula is a medium-firm density which research shows is the most recommended by both chiropractors and orthopedic surgeons. The head and ankle zones are the same and the shoulder and lower leg zones are the same, so when the mattress is rotated, the zones are maintained. Our core is made from 100% natural rubber direct from the finest rubber plantations in Sri Lanka and also the first plantation in the world to receive organic latex certification. Our natural latex uses absolutely no synthetic blended latex or poly foams. It costs more for us to produce a zoned core, but we feel the long-term benefits outweigh the price.
ERGONOMIC BENEFITS OF ZONING Research has shown that support for your spine can help keep your back healthy; therein lies the myth of getting a "firm" mattress. But really it's not about being firm overall, it's about having "anatomically correct" support. By designing the support to have more firmness where your spine needs it the most (at the natural inward curve where our bodies are also the heaviest), then a firmer mattress in the center can help provide the necessary alignment to give you the perfect configuration. We designed our zoning to be a little firmer in the middle, but not drastically. It's a smooth transition to offer a bit more support in the center where you need it most.
THINGS TO KEEP IN MIND Although our core is zoned to offer subtle contouring in the shoulders and more firmness in the middle center-third, keep in mind that this is still considered a firm mattress. Basically our core is the "foundation" of support for your mattress (similar to an innerspring support system). Now, many folks who really enjoy a firm mattress will like to sleep directly on the core, others will want to add layers of softer latex above the zoned core to provide some cushioning. Adding some comfort layers doesn't make the zoning worthless, since the zoned core is the structural foundation of support, and every great mattress always starts with a great support system at the base. You'll get that with our 5-zone core without having to choose if you want Extra-Firm, Firm or Medium at the base. Instead you choose what you want on the TOP comfort layers (medium, soft, or somewhere in between).
If you know you prefer a firm mattress then go with our CORE or CUSH which offers the most direct contact with the support structure. If you lean more towards a medium or soft comfort preference, then choose our PLUS (our most popular) which features 3" medium latex on top of the core for more cushioning. If you love the sensation of sinking into something cuddly soft on the surface, just add our LaNoodle Cuddle Top for the 5-star hotel experience.
Much of your consideration will be determined on your height, weight and sleeping position. Lighter people will find sleeping directly on the core more firm than someone with more body weight. Likewise, side sleepers who are curvy (especially if thin or older) may need some softness on top of the support core. For co-sleepers at opposite ends of the spectrum we offer dual comfort (half firm, half soft, etc). But our experience has shown that about 95% of customers fall into our medium-soft range of core support with a medium or medium-soft comfort layer. If you like the added luxury of a soft surface that cuddles you, but doesn't compromise support, then add our LaNoodle Cuddle Top for an extraordinary experience of comfort (this is what we recommend to 5-star hotels).
ZONING MISCONCEPTIONS The average sleeper places their head at the top area where the pillow lies. This is followed by the shoulders resting in the second zone (approximately 15" from the top). The lumbar, hips and thighs (usually the heaviest part of our body) then rest in the center-third of the mattress zone. Because our lower-legs and ankles don't carry too much weight, zoning is not as critical in those areas (but we provide symmetrical zoning so you can rotate your mattress). Children, and very small adults, often don't feel the zoning since they are so light and don't have the "weight" to distribute any significant force. They will, however, still benefit from the superior resiliency and support of our 5-zone core.
ADJUSTMENTS Yes it's really true. Getting a new mattress can definitely have some initial pains of tossing and turning the first few days (or even weeks) especially if you've been sleeping on an older mattress that was too soft. Similar to a new pair of shoes that need breaking in before you fall in love with them, a new mattress may also need a breaking-in period where your body adjusts to the new support.
LOWER BACK PAIN Usually pain in the lower back is caused by a mattress that is too soft and doesn't provide proper firmness. Also remember that studies have shown stress also manifests itself in the lower back. This can be a double-edged sword; the more sleep we lose the more stress we have... so is that pain from your mattress or from stress?
HISTORY OF LATEX MATTRESSES
SUPERIOR MATTRESS MATERIAL In 1929 the first latex foam (Dunlop) was invented and used for seat padding, then in 1931 the world's first latex mattress was made. The features of not having to be flipped, staying fresh, responsive, supportive and keeping its shape made the mattress a huge success.
PROVEN TO PROVIDE HEALTHIER SLEEP The year 1954, latex foam is proven to contain exceptionally high anti-bacterial properties by Dr. Theo Lammers from the Institute of Hygiene Gutenburg University*, making it the hygienic ideal for mattresses, superior to all other materials: unsurpassed in comfort and support, exceptional durability, stays cool, and is the healthiest choice due to its high anti-bacterial and allergy-free properties.
IDEAL FOR ASTHMA AND RESPIRATORY DISORDERS Further work in 1956 by Drs Fuchs & Gronemeyer at the Asthma Clinic, Bad Lippsinge, entitled 'Relief of nightly attack of asthma', concluded, "the advantages of latex foam mattresses have been outlined by health and surgical authorities and the bacteriostatic as well as fungus and mite resistant properties of latex material found by Lammers is confirmed".
Throughout the decades, the cost of this premium material made it more expensive for manufacturers to produce and consumers often didn't want to buy this higher priced option, thus latex mattresses were soon overshadowed by beds made with batting or synthetic foams placed over innerspring coils.
BOUNCING BACK In the mid-1990's, natural latex mattresses were making a small comeback. In fact, our flagship mail order catalog, Tomorrow's World, was one of the first companies to start offering consumers nationwide a selection of latex mattresses made with organic cotton and wool. The years 2008 to present have enjoyed a huge resurgence of natural latex mattresses which are now offered by many manufacturers and retailers across the country. Consumers are beginning to understand the value equation of their purchases and realize that in many cases you really do get what you pay for, so investing in a quality latex mattress will pay for itself many times over the lifetime of use it provides. Staying true to our history of providing our customers with the best innovation using only natural materials, we continue to develop and create exceptional sleep products that surpass your expectations.
DECEPTIONS The popularity of latex mattresses comes with a price to consumer research. Many "so called" latex mattresses often only contain a small layer surrounded by foam and/or coils. Some "natural" latex really only contains a percentage of natural. Even materials such as "organic cotton" are being advertised on certain mattresses when in fact the fabric is blended with synthetic polyester. In this era of popularity for latex mattresses it's imperative for the consumer to do thorough research so they can be 100% sure they are getting the product they think they are purchasing.
HOW OUR NATURAL LATEX RUBBER IS MADE Rubber tapping is the process by which rubber is gathered. An incision is made in the bark of a rubber tree, which cuts through the latex vessels that flow between the bark and the cambium. The latex then drips into a vessel. Each night a rubber tapper must remove a thin layer of bark along a downward half spiral on the tree trunk. If done carefully and with skill, this tapping panel will yield latex for up to 5 years. Then the opposite side will be tapped allowing this side to heal over. The spiral allows the latex to run down to a collecting cup. The work is done at night or in the early morning before the day's temperature rises, so the latex will drip longer before coagulating and sealing the cut. Rubber tapping does not hurt the trees and it's a great way for the indigenous people to make a living using their natural resources.
Each rubber tree weeps 15 grams of latex daily (about one tablespoon) . A Queen size Core needs the daily output of 2500 trees ,spread over 12 acres of rubber plantation, providing a living to eight rubber tappers. Interestingly, these rubber trees accounts for the removal of 143 metric tons of Carbon Dioxide from the environment every year.
A sixteen-point quality control procedure assures consistent quality from raw materials to final product. The foaming, gelling and vulcanizing process uses a high-tech, computer controlled foaming machine made in the USA; air is blended with latex to achieve required density & hardness of the latex. The steam cure technique (designed with engineered stainless steel pin moulds for energy efficiency), keeps the natural latex characteristics undisturbed through the vulcanizing process. A multi-cycle washing method using drinkable quality water to ensure a clean and pure product. And exclusive soft condition drying mechanism, enhances the natural feel of the latex.
COMPARISONS OF LATEX AND POLYURETHANE FOAM
You have natural latex, synthetic latex, and also a blend of the two. Then you have polyurethane foams, memory foam (such as Tempurpedic), and conventional foam.
Latex is NOT polyurethane foam. In its natural form, latex is a milky white liquid tapped from the trunks of rubber trees (hevea brasiliensis) and then combined with water to create a thick suspension. In manufacturing natural latex foam rubber, the latex suspension is whipped to a froth and poured into carousel molds, onto a conveyor, or into sheets (for sponge rubber carpet cushion), sometimes additionally frothed using CO2 gas, chilled to below freezing, and then heated to the point of vulcanization (about 240°F). During vulcanization, molecular crosslinks are formed giving the resulting foam rubber the ability to recover its shape after compression. Natural latex is not blended with synthetic styrene-butadiene rubber; it's derived exclusively from the rubber tree.
CozyPure uses ONLY NATURAL latex rubber - NO SYNTHETICS
Synthetic latex foam rubber represents a group of materials manufactured using methods similar to natural latex rubber but produced using a totally synthetic process with styrene-butadiene rubber (SBR) and polymerized chloroprene, known as neoprene.
Blended latex accounts for the majority of latex used in the marketplace. It's usually comprised of 20% to 40% natural latex with 60% to 80% synthetic SBR latex. There is no polyurethane content in either natural or synthetic latex.
First, don't be fooled about the "eco" or "healthy" benefits of "Soy Foam"; only 10% to 20% of soy is used, the rest of the foam (80% - 90%) is made from petroleum based oil, just like all foams (including memory foam). There's nothing wrong with adding soy, in fact we think it's a great place to start, but just be aware there's really not much soy content. Until they can find a way to incorporate more soy into the product, we're not exploring this as something to use at this time. In our eyes, "eco-friendly soy foam" as it stands now, is a perfect example of green-washing.
Memory foam is polyurethane with additional undisclosed "proprietary" chemicals increasing its viscosity and density. Conventional polyurethane foam is made by mixing polyols, diisocyanates, catalysts, auxiliary blowing agents and other additives and allowing the resulting foam to rise. Both types of foams are plastic-based and dervived from petroleum oil.
The United States Environmental Protection Agency published two documents proposing National Emissions Standards for Hazardous Air Pollutants (HAP) concerning hazardous emissions produced during the making of flexible polyurethane foam products. The HAP emissions associated with polyurethane foam production include methylene chloride, toluene diisocyanate, methyl chloroform, methylene diphenyl diisocyanate, propylene oxide, diethanolamine, methyl ethyl ketone, methanol, and toluene however not all chemical emissions associated with the production of these material have been classified. Methylene chloride makes up over 98 percent of the total HAP emissions from this industry. Short-term exposure to high concentrations of methylene chloride also irritates the nose and throat. The effects of chronic (long-term) exposure to methylene chloride in humans involve the central nervous system, and include headaches, dizziness, nausea, and memory loss. Animal studies indicate that inhalation of methylene chloride affects the liver, kidney, and cardiovascular system. Developmental or reproductive effects of methylene chloride have not been reported in humans, but limited animal studies have reported lowered fetal body weights in rats exposed.
