The "Global Organic Latex
Standard", GOLS in short, is the newly introduced standard
for sustainable processing methods of latex products from organic raw materials.
This mainly addresses the standards which need to be maintained with relevance
to processing, manufacturing, packing, labeling, trading and distribution
of latex products. In addition to the use of organic raw material, this standard
also concentrates on aspects such as human health, safety and welfare, and
environment in the manufacturing process of latex products. Product
labeled as “Made with Organic†or
“Contains Organic†should contain minimum
95%. or more of certified Organic latex (as per 2.1) and other certified
Organic raw material (as per 2.2) in the final product, from its total weight.
Balance 5% may contain non-organic products other than Natural or Synthetic
latex. Any textiles materials used in the semi final or final products may
be excluded from this calculation, however should be certified
“Organic†as per GOTS
standards or certified as per OE 100.
Only textile products that contain a minimum of 70% organic fibres can become GOTS certified. All chemical inputs such as dyestuffs and auxiliaries used must meet certain environmental and toxicological criteria. The choice of accessories is limited in accordance with ecological aspects as well. A functional waste water treatment plant is mandatory for any wet-processing unit involved and all processors must comply with minimum social criteria. The key criteria of GOTS, its quality assurance system and the principles of the review and revision procedure are summarised in this section.
Native to the Amazon Rainforest
Latexpedic® comes from the Hevea Brasilienis tree, originally native to the Amazon Jungles of Brazil. (the first rubber ball was invented by the Mayans over 3500 years ago.) Latex is white and milky in appearance, has an elastic consistency, and is removed from the tree through a process called "rubber tapping" - similar to tapping trees for maple syrup. Just two centuries ago, the Havea Brasillienis treee was exclusive to the Amazon Rainforest. It wasn't until the 1870s when rubber tree seeds were brought to India to help establish the first commercial rubber plantations. Today, the Hevea Brasillienis trees are grown in tropical climates around the world. |

What actually is
it?
Latex foam
mattresses are defined as: Any of several
natural or synthetic colloidal polymers suspended in an aqueous solution.
Basically: rubber particles in
water
WHAT IS
NATURAL LATEX
MATTRESSES?
Natural Latex is a milky substance harvested
from rubber tree plants (Havea brasiliensis) which are grown in tropical
climate plantations around the world. Most are located in Africa, Malaysia,
South America, and Indonesia. Natural Latex is bio-degradable and naturally
resistant to mold, mildew & bacteria.
Harvesting the liquid
latex
foam mattresses is similar to tapping trees for maple syrup. The trees
are not harmed, providing a sustainable resource. The latex is collected
in buckets and shipped to large rubber factories such as B.F Goodrich, Dupont,
etc. for processing. Natural liquid latex is a commodity
that’s publicly traded in stock markets around the world
similar to corn, pork bellies, orange juice
etc.
WHAT IS SYNTHETIC
LATEX?
Synthetic latex is a man-made molecular
copy of natural latex. The scientific name for this compound is Styrene-Butadiene
(SBR).
Styrene is named for
“styraxâ€, the resin from a Turkish tree.
Low levels of styrene occur naturally in many kinds of plants as well as
a variety of foods such as fruits, vegetables & nuts.
Butadiene is produced by dehydration
of butane obtained from petroleum. Butadiene is also used in the manufacture
of latex paints and nylon fibers used in rope and clothing.
WHAT are
BLENDED
LATEX foam mattresses ?
Blended latex is just what it sounds
like, a combination of Natural latex and Synthetic latex mixed
together.
WHICH
LATEX
MATTRESS IS BEST FOR
ME?
This is a question
that’s answer can depend on your perspective. All latex
formulas offer numerous benefits to consumers that far outweigh the benefits
of conventional foam bedding materials. Keep in mind that while latex
formulations are contrasted with each other below, all latex rubber significantly
outperforms foams such as memory foam or traditional polyurethane foam for
durability, pressure relief and sleep benefits.
NATURAL
LATEX
SYNTHETIC
LATEX
Synthetic Latex is extremely uniform
at the molecular level, so sleep products will have greater durability than
those made solely with Natural Latex. However, what you gain in durability
you lose in feel and sleep benefits as compared to Natural Latex.

CLASSIC BLENDED LATEX
When consumers want to know a product
is natural and good for the environment while also looking for a product
that will help them sleep better with optimum value for their money- they
purchase blended latex. By combining Natural Latex and Synthetic Latex together
you get the best of both worlds. Natural components, elasticity, conformity,
health benefits and luxurious feel from Natural Latex combine with extended
durability from Synthetic Latex- to make a product that the Earth provided
and we perfected.
Blended latex can be compared to a gold
wedding band. No one has a 24 karat (100% gold) wedding band because it would
be too soft and bend if gripped too hard. The solution is an 18 karat gold
ring where the gold is mixed with another, more durable metal. The result
is a ring that has the look and feel of pure gold but is less vulnerable
to damage or wear.
How Latex is
Made
Making Latex –
Manufacturing Processes
The terms
“Talalay†and
“Dunlop†refer to the two different methods
of manufacturing Latex Rubber for sleep products. The Dunlop process was
developed in 1929. It was the first method used to produce latex material
for bedding.
As technology progressed, the Talalay
process was developed by the Talalay family during World War II. The Talalay
process for producing latex is significantly more complex and costly, resulting
in softer, more buoyant and luxurious finished products.
MAKING LATEX - LATEX
FORMULAS
Both Talalay and Dunlop processes start
with a formula mixture of liquid latex. These formulas can be any of the
following:
100% natural latex rubber (harvested
from rubber tree plants)
100% synthetic latex rubber (a man-made molecular copy of natural latex
rubber)
Blended natural & synthetic latex rubbers (specific blend ratios are
proprietary)
Note: there are
small amounts of other materials required for processing liquid latex into
solid form which are necessary for all latex production. (ingredients &
amounts are
proprietary)
Latex International Talalay is produced
using only 100% Natural or Blended formulations to meet optimum quality
standards.
Latex
Processes
TALALAY
1. Liquid latex formulation is poured
into a mold and sealed closed
2. Vacuum is created to disperse liquid latex throughout mold
3. Liquid latex is flash frozen
4. Frozen latex is flash heated to “gelâ€
into permanent solid form
5. Cooled solid latex is removed from
mold
DUNLOP
1. Liquid latex formulation is poured
onto a long conveyor belt
2. Liquid latex is slowly heated to “gelâ€
into permanent solid form
3. Cooled solid latex is removed from conveyor
belt
Latex Bliss is owned by Latex International, America's manufacturer of Latex Foam Mattresses. They have a fine collection of Latex Foam Mattresses. Available at our Burbank Showroom.
The difference in processing are the
two additional steps that occur with Talalay Process - #2 vacuum & #3
freeze .
#2 Vacuum –
This
allows any amount of latex to be evenly distributed throughout the mold creating
precise and varied firmness with the finished latex. The more liquid latex
that’s poured into the mold the firmer the resulting solid
latex. Therefore, if less liquid latex is used, a softer more supple piece
of latex results.
This differs from Dunlop in that Dunlop
process has very little ability to vary the firmness or feel of the finished
solid product while maintaining its structural integrity. The liquid formula
is poured onto a belt and you get the same, dense piece of latex every time.
The only way to soften the feel of Dunlop latex is to add
“fillers†into the liquid latex formula
which result in solid latex that is flaky and breaks down quickly.
#3 Flash Freeze
–
This provides Talalay with its uniquely consistent characteristic.
Liquid latex is a suspension of rubber particles in water,
like a shaken snow globe. Flash freezing prevents the latex particles from
settling to the bottom while gelling into a solid product. This means that
the resulting piece of solid Talalay latex has the same consistent feel from
top to bottom.
This differs from Dunlop because Dunlop
process does not utilize a freeze step. Therefore, the rubber particles settle
to the bottom while the liquid latex is gelling into a solid form, like a
snow globe, resulting in a variation of feel from top to bottom. This is
not recognizable if the Dunlop latex is used as a bottom layer of a mattress
but can cause problems if Dunlop pieces are used for pillows or as top layers
of a mattress.
CONCLUSION - The Talalay process takes four times looonger
than Dunlop with two additional process steps that improve the consistency,
quality and feel of the finished latex.
A simple analogy: Talalay latex is like
a chocolate soufflé; although the process is long, your end
product is a buoyant, airy, complex delight. Dunlop latex is more like a
tray of brownies; tasty, but dense and flat in comparison.
Our commitment to perfection: From the
selection and mixing of raw materials to final product testing and assembly,
our entire manufacturing facility utilizes the latest technology to create
the most supple, resilient and comfortable Talalay Latex sleep products in
the world.
But of course, all this technology
won’t get you anywhere without smart, talented professionals
to bring all the elements together assuring great finished products are delivered
to your home every time.
Talalay latex is the premier material in
bedding, LI Talalay delivers a unique
buoyant quality which relaxes muscles and relieves tension, lifting away
the pressures of the day while you sleep. Careful attention to detail at
every step makes certain this amazing feel comes through in the finished
product.
To help understand what makes our Talalay
Latex so exceptional, think of an artisan chef creating a light and airy
chocolate soufflé!
Use the best recipe
–
Next, we mix our premium ingredients into a
liquid latex foam formula or
“batterâ€. Creating different formulas
of liquid latex “batterâ€, we meet specific
customer requests for 100% natural or more commonly used blended
natural/synthetic latex recipes. Think dark chocolate vs, milk chocolate-
it’s a matter of personal taste and desired product attributes.
Measure Carefully-
As
any great baker knows, if you don’t measure correctly the
soufflé will fail. Our advanced, state of the art automated
systems control both the mix of the batter and the precise amount poured
into each mold to attain specific results every time.
Test for Perfection -
Once
the process is complete, every mattress core is robotically tested in 9 areas
to assure a consistent feel from head to toe. Each pillow is individually
weighed and hand inspected.
Share the Results -
Even
the best ingredients and the finest materials can be used poorly. To assure
great finished products, we follow through by sharing knowledge with our
retail and manufacturing partners. Together, we design and deliver finished
pillows, mattress toppers and mattresses that bring the uplifting benefits
of Talalay Latex to the surface.

All of our Talalay products are made
with Natural Talalay Latex Rubber, which starts as sap from the Havea
brasiliensis tree. These rubber trees have a 25 year productive life and
a strong positive effect on the environment as they quickly absorb carbon
dioxide from the atmosphere and help reduce greenhouse
emissions.
Our Talalay process features natural,
biodegradable ingredients that come from renewable resources and water-based
raw materials: natural latex, air, and water. Our process does not use solvents
and does not damage the ozone layer. Our clean and green approach carries
through to our end products: Talalay latex contains no toxic chemicals while
standard Poly Foam and Memory Foam (visco) can contain as many as seven toxic

LI Talalay Latex provides 33% more Pressure
Relief than leading Memory foam.
Pressure from your mattress and/or pillow
prevents your muscles from relaxing which makes it difficult to fall asleep
and impairs circulation causing you to toss & turn which makes it difficult
to stay asleep.
Therefore, the less pressure your mattress
and pillow produce on your body the easier it is to fall asleep and the more
complete sleep you achieve throughout the night which leads to more energetic
and productive days.

Latex International
Talalay Latex is 4x more durable than other latex and 20x more durable than
traditional bedding foams.
At Latex International, we continually
ensure that our formulas will last the test of time. Using the standardized
ASTM Cornell Indentation test we prove that our Talalay outlasts any other
material used for bedding today.
This is the most rigorous and material
damaging ASTM standardized test that exists for bedding components. While
Latex International Talalay performs flawlessly over a period of 12 hours
representing decades of use, other latex’s break down much
more quickly and foams such as memory foam and polyurethane foam actually
tear apart within minutes.
The strength of our material allows
LI to match any warranty that retail stores choose to offer on their products
and assures maximum value for consumers.
Latex International Talalay Latex breathes
up to 7x better than other latex or foams for cooler sleep.
One of the fastest growing concerns
with bedding today is sleeping hot. This is a legitimate concern because
not only is it uncomfortable, sleeping too hot interrupts the quality of
our sleep as we continuously move to find a cooler spot. This can occur from
both mattresses and pillows.
The heightened
awareness of sleeping hot is primarily due to increased use of Memory Foam
in mattresses.
Memory Foam has a collapsible cell structure that
traps body heat and radiates it back at us resulting in uncomfortable
perspiration.
Talalay Latex is sometimes confused
with Memory Foam because of extensive Memory Foam advertising. Nothing could
be farther from the truth. The Talalay Latex rubber cell structure resists
collapsing and allows air to circulate. This breathability whisks away our
body heat preventing mattresses and pillows from becoming an oven.
Latex International has gone one step
further and developed Talalay GL which is a unique formulation of Talalay
Latex with special phase change properties. Talalay GL actually helps regulate
the consistency of body temperature for a temperature neutral sleeping
experience.

LI Talalay Latex is Mold, Mildew
& Bacteria proof and Dust Mite resistant
Most people don’t
consider their mattress as a contributing source for respiratory problems
and allergic reactions. We think of our bed as a “safe
havenâ€. The reality can be much more yucky.
Mold, mildew, bacteria and dust mites
love our beds & pillows. We shed millions of microscopic skin cells and
perspire nearly 1 pint of water every night. The microscopic skin cells and
water vapor fall through the weave of our linens and mattress cover landing
on the cushioning layers below where they become a food and water source
for mold, mildew, bacteria and dust mites- it can’t be
avoided, and it's gross.
Whether your “landing
pad†cushion layer is hospitable to these infestations
is the controlling factor to the amount of hazardous dust created from your
mattress & pillow.
Foams such as Memory Foam &
Polyurethane Foam are environments
where these contaminants thrive, so if they compose the top cushion layers
of your mattress you may have a problem.
Independent testing shows that Latex
International Talalay Latex is mold, mildew & bacteria proof- these organisms
simply won’t grow on it. Furthermore, it’s
dust mite resistant so these critters will prefer to be elsewhere, not right
next to your face as you sleep.
Try to find a healthier bedding material,
we dare you.
In a perfect world all bedding products
would be as safe as Latex International's Talalay Latex. The reality is that
today’s technology for producing foams like Memory Foam
or Polyurethane Foam simply aren't.
Today’s foams may
contain any or all of the following, each are known carcinogens.

Latex International Talalay
Latex contains none of
these.
Zero cases of allergic reactions to
LI products have been reported.
Latex International Latex Mattresses have been
making Talalay pillows and mattress components for over 35
years. Every year millions of products
are sold using Latex International
Talalay.
The FDA tracks allergic reactions to
latex products in the USA. Not once has there been a report of an allergic
reaction attributed to any of our Talalay
products.
Latex International is the only latex
producer that tests every block of mattress material in 9 separate areas
to insure consistency throughout each piece. This means that retailers and
consumers can be sure that products delivered or brought home will match
the products experienced in the showroom every single time.
Because pillows are not able to be measured
in the same way as block mattress material, we electronically weigh and then
hand inspect every pillow for quality and consistency. This is an extra time
consuming step in our process, but it’s the only way to
be completely sure that consumers receive the very highest quality pillows
every single time.
Of the top four mattress companies in
the US, one spends more on annual advertising than the other three combined.
This company makes only Memory Foam beds. They spend tens of millions every
year advertising Memory Foam to consumers. To counter this, the remaining
top three US mattress companies (who make metal coil mattresses) also make
Memory Foam beds and advertise theirs to stay competitive.
Hence, the circle of abundant advertising
for Memory Foam.
Due to this advertising, many people
assume that all non-coil beds are made with Memory Foam or that Latex and
Memory Foam are the same thing. This couldn’t be farther
from the truth.
In fact, the two materials are actually
polar opposites and the sleeping experience could not be more different!
Latex International Talalay Latex actually outperforms Memory Foam in every
way.
Sleeping hot is the #1 complaint from
Memory Foam owners. This is because Memory Foam requires body heat to collapse
the Foam cell structure in order to conform to your curves, the collapsing
of these cells restricts air flow trapping body heat and radiating it back
at you.
Latex International Talalay Latex
is 7x more breathable than memory foam. The rubber cell structure
doesn’t collapse. Its natural resistance
lifts your body preventing collapse
and allows air to flow through, creating an escape path for body heat.
You won’t have to
continuously flip your Latex International Talalay Latex pillow or search
for a cooler spot on your LI Talalay Latex
bed.
Our Talalay Latex is a two-dimensional
material; it’s simultaneously supportive and pressure
relieving, where memory foam is a one-dimensional- pressure reliever only.
Your body sinks into and through Memory
Foam until you hit a separate support layer below. Memory Foam simply
can’t accomplish both pressure relief and support on its
own. Hitting the support layer below Memory Foam increases pressure on your
body.
Latex International Talalay Latex is
different and testing proves it.
Our Talalay Latex is the best pressure
relieving material used in bedding today. It provides the ultimate in pressure
relief so your muscles relax to fall asleep quickly and your circulation
can flow to stay asleep soundly.
Memory Foam, even so called
“soft†memory foam has a hard dense feel
that is unappealing to many. Some call it “getting stuck
in the mud†because after a few minutes your body heat
collapses the cells and you sink into a hole molded to your body. It soon
becomes very difficult to move or get out of bed, you become trapped in a
temporary crater.
Latex International Talalay Latex contains
naturally based rubber material that gently lifts your body for a light &
bouyant experience. Our Talalay Latex instantly conforms and moves with your
body, providing postural support and exceptional muscle relief no matter
what sleeping position you maintain.
Latex International Talalay Latex is
like floating- truly luxurious.
Our Talalay Latex uses naturally derived
material harvested from rubber trees that create an inherently hypoallergenic,
dust-mite resistant, mold & mildew proof sleeping environment, making
it ideal for allergy sufferers or anyone wanting a cleaner bed. In addition
our Talalay Latex doesn’t off gas harmful compounds that
may be present in Memory
Foam.
Cornell Indentation testing proves Latex
International Talalay Latex is 20x more durable than leading Memory Foam.
While leading Memory Foam tears apart during this industry standard ASTM
quality test, our Talalay Latex passes with flying
colors.
Latex International manufactures Talalay
Latex Support Cores and Pressure relief layers used by top mattress manufacturers

Down the Truth / TalaTruth
FROM THE DESK OF DR. JOHN LEAN, PH.D.,
CHEMIST
Sometimes we find
that we just have to go to the doctor and get some straightforward information
about the facts and science behind
latex.
Block latex foam rubber is the general
term used to describe latex foam rubber produced with a large enough cross
section to be used for mattresses, pillows, and cushions. Block latex foam
rubber is produced by two different processes: the Talalay Process and the
Standard (Dunlop) Process. Both processes use the same basic ingredients:
natural rubber latex (NR), polystyrene-â€butadiene rubber
latex (SBR), soap, reinforcing filler, sulfur, and vulcanization
agents.
Natural Rubber
Latex – Naturally occurring
polyisoprene polymer produced by rubber trees and extruded in the sap. The
rubber tree sap is collected, concentrated, and preserved with ammonia before
being sold.
Polystyrene-butadiene Rubber
Latex
– Polymer produced from styrene and butadiene designed
to mimic and improve upon natural rubber. The polymer is produced in water
on both batch and continuous production lines. After polymerization, the
latex is stripped of residual reactants and concentrated before being
sold.
Soap –
Natural soaps are used to stabilize the various components in the
mixture.
Reinforcing Filler
– Hard materials are added to the mixture
to increase firmness.
Reinforcing fillers are of two general
types; mineral or plastic. Mineral fillers are generally aluminosilicates
such as Feldspar or calcium carbonate (talc). The most commonly used plastic
filler is polystyrene resin. Mineral fillers incorporate well into the
rubber matrix and tend to be well dispersed. Plastic fillers
are typically introduced as a latex and tend to form clusters in the rubber
matrix. The plastic clusters are prone to breaking apart under use leading
to softening.
Sulfur –
Elemental sulfur forms crosslinks between polymer chains when heated giving
the latex rubber foam strength and structure.
Vulcanization Agents
–
Agents
used to increase the crosslinking rate and effectiveness of sulfur. The agents
are typically consumed in the process. The above components are mixed together
in a water based system to form what is termed compound for both
processes.
1. Latex compound
is injected with air and frothed to form
foam.
2. The foam is
poured into an aluminum mold. The mold is only partially filled with
foam.
3. The mold is
closed. The pressure inside the mold is reduced to create a pressure differential
between the cavity of the mold and the air in the foam bubbles. Since the
air in the foam bubbles is at atmospheric pressure and the mold pressure
is lower than atmospheric, the air inside the bubbles expands causing the
bubbles to increase in size expanding the foam. The foam expands and fills
the mold. At the same time the foam redistributes itself evenly in the mold
since the pressure inside the bubbles is driven to equalize over the entire
block. Equalization of pressure in all the bubbles leads to a very uniform
density throughout the foam
block.
4. The water in
the foam is then frozen.
5. After freezing,
carbon dioxide is injected. The carbon dioxide reduces the pH of the foam
and reduces the effectiveness of the soap at stabilizing the rubber in the
latex. The rubber particles coalescence forming a continuous, open cell,
solid block of foam rubber.
6. The foam is
heated to vulcanize the
rubber.
7. The foam is
cooled and demolded.
8. The foam block
is washed and dried.
STANDARD (DUNLOP)
PROCESS
1. Latex compound
is injected with air, a gelling agent, and frothed to form foam. The gelling
agent reduces the pH of the foam and reduces the effectiveness of the soap
at stabilizing the rubber in the
latex.
2. The foam is
poured into a mold until it completely fills the mold making it critical
that the foaming process in well controlled to achieve an even density throughout
the block.
3. The mold is
closed. The mold is allowed to rest until the gelling agent has enough time
to destabilize the rubber in the latex. The rubber particles coalescence
forming a continuous, open cell, solid block of foam
rubber.
4. The foam is
heated to vulcanize the
rubber.
5. The foam is
cooled and demolded.
6. The foam block
is washed and dried.
Advantages of the Talalay Process:
the resulting feel, the uniformity, and the ability to reach low densities
of the foam block as a result of the expansion of the foam to fill the mold
under reduced pressure (rather than the complete filling of the mold as in
the Standard (Dunlop) Process).Advantages of the Dunlop Process: shorter
production times and ease of
manufacture.

REVIEWS NATURAL LATEX
MATTRESSES: Talalay
Latex Mattresses of Rubber
Foam
offer superior feel and comfort in bedding materials because of its unique
compression profile.
Compression is how a material responds to a weight
or load being placed on it. A material will resist the load and push back
in proportion to the load and the material’s ability to
carry the load. The manner in which a material responds to a load defines
how the material feels to the touch and how it supports the load. Below is
a graph showing the amount of force needed to compress a piece of latex Rubber
rubber and a coil spring a percentage of the original
height.
RATINGS LATEX
MATTRESSES: As shown in the above graph, a
coil spring has avery linear response to the applied load. The linear response
of a spring is an inherent property.
Talalay
Latex Rubber Foam Mattress on the other hand responds to the applied load
in a non-linear fashion. Initially Talalay Latex Rubber increases in
firmness in response to the load, but as the load increases Talalay Latex
Rubber compresses to a greater extent. Talalay Latex Rubber will support
just as much weight at the coil spring, but it has more give keeping the
material from having the feeling of bottoming
out.
The increased compressibility
of Talalay Latex Rubber Foam is what allows the material to shape itself
and comform to the human body. The
human body’s profile is not flat and its weight distribution
is not even. A coil spring is only able to respond to a
body’s weight and not its shape. Talalay Latex Rubber with
its non-linear compression curve can respond to a body’s
weight and shape. A person may have similar weight distribution between the
shoulders and hips, but the body parts have very different
shapes.
Talalay Latex Rubber has the ability
to allow for more compression without a proportional increase in weight to
conform to various body shapes and weights.
Also contributing to
Talalay
Latex Rubber Mattresses unique feel and support is the
material’s resiliency. Resiliency is the amount of energy
returned by a material after compression. Resiliency in a Rubber material
is important for support. Below is a graph of showing the compression and
decompression of Talalay Latex Rubber and a Dunlop latex Rubber. The arrows
indicate compression and decompression.
The unique, non-linear
compression profile of
Talalay Latex Rubber is the result of the material’s large,
open cell structure. Every cell of Talalay Latex Rubber behaves as a
micro-spring.
The initial increase in firmness upon
compression is the result of the latex Rubber cells resisting the compression
until the cells buckle. Cell buckling results in the non-linear response
of Talalay Latex Rubber to compression. Talalay Latex Rubber has a more non-
linear response than Dunlop latex Rubber because of its larger cell
size.
Buckling
latex Rubber cells are nothing to worry about since there are hundreds of
other cells backing them up.
Talalay Latex Rubber cells are also made of one of the most
durable materials around, rubber, so they bounce back into shape. The millions
of Talalay Latex Rubber cells work together to provide just the right amount
of support and
comfort.
