Can people who suffer from “latex allergies” sleep on latex mattresses or the natural latex mattress topper?

Pure natural latex is derived from the rubber tree. Most latex mattresses and pillows are made from 100% natural latex, but can be made from a blend of natural and synthetic latex.

Latex allergies first became noted in the 1990s. Proteins in the latex are the source of the allergic reactions, which can include: nasal congestion, runny nose, shortness of breath, wheezing and in the extreme case, anaphylactic shock. These particular proteins also occur in many common items such as tomatoes, bananas and milkweed. Most of the early cases of latex allergies stemmed from the health care community in persons regularly exposed to latex materials such as latex gloves. These types of latex products are manufactured by the dipped vulcanization process which is a closed cell process; this process does not allow for the proteins to be washed out during or at the completion of production. Moreover, to facilitate their wear, latex gloves are coated with a powder, which in turn allows for the latex proteins to be carried into the air and increases the likelihood of exposure.

Latex foam used in the manufacture of latex foam mattresses is made with an entirely different process called an open celled process. This process allows for thorough post-production washing. Most latex foam bedding is put through at least 5 washing or flushing cycles to ensure that almost all of the protein is removed from the latex. All latex foam bedding products are subsequently covered with non-latex products so there is never skin contact with the latex.

The FDA monitors complaints for allergic reaction to natural latex rubber. The largest manufacturer of natural latex products in the United States has reported that in their 28 years in the industry, there has never been a single complaint generated from the natural rubber found in latex pillows or mattresses.

As a precaution, severe latex allergy sufferers should obtain a mattress materials sample to be taken to their physician or allergy specialist for evaluation and recommendation.

Rocky Mountain Mattress does provide latex samples upon request for those who wish to test for allergies before purchasing. You can find our full selection of latex mattresses and toppers here

American made memory foam vs. Chinese made memory foam

Monday, June 13th, 2011

In the world of memory foam manufacturing, there is a clear and noticeable difference between American made memory foam and Chinese memory foam.

Quick Summary: American memory foam will last longer, as a result of almost always being made with 100% visco-elastic memory foam. Also, American made memory foam is produced in a vacuum, giving the product consistency of quality and support.

Chinese manufacturers will often add clay fillers to their memory foam that cause it to break down quicker, forming depressions. In addition to this, there is speculation that certain Chinese foams contain carcinogens (cancer-causing agents).

Therefore, Rocky Mountain Mattress carries only USA made memory foam. We have elected to carry Bayer Memory Foam and Foamex Memory Foam. Both memory foam brands are made here in the USA and have excellent reputations for producing quality memory foams that last.

Mattress Density: You Get What You Pay For, Buyer Beware, and Higher—Not Always Better

Density is an important word in the memory foam mattress world. Memory foam density is an important indicator of durability and performance quality. But a true measure of density depends on who is manufacturing the memory foam and their level of commitment to creating a consistent, quality product.

Density numbers have a small window wherein lies the “sweet spot.” High density is generally equated with a quality product, however, there is such a thing as too much density. Two of the main complaints of memory foam mattress owners is the temperature of the foam during sleep or the slow rebound time when turning over—both arguably annoying factors in an interrupted sleep, and both the result of too much density.

Usually, mattresses are not a popular import item because of their bulk and the cost to transport them. The advent of memory foam eliminates those problems; its very nature allows for its extreme compression during shipping thus significantly cutting space and cost concerns. Currently, the U.S. is being inundated with Chinese memory foam that advertises “high quality” or at the very least, “adequate” density, but when put into use is turning up questionable characteristics. Some complaints include: slowness to rebound, increased (and unwanted) firmness as the room temperature decreases, hot spots after laying on it for a period of time, oily residue on the mattress surface, and the presence of chemical odors. The chemical smells are most concerning as there is very little regulation of purity or safety in the manufacturing of Chinese memory foam. The smells take a very long time to dissipate (if ever) and have various potentially harmful sources, one of which is the alleged use of pesticides used to kill insects. There is great speculation that Chinese memory foams contain cancer-causing chemicals (carcinogens), another possible odor source. Mattress industry insiders also trade concerns about reports that Chinese memory foam may contain lead, stone dust and clay fillers to fabricate the appearance of a higher density—which commands a higher price. The result of this “enhancement” is a quicker formation of depressions and a rapid breakdown of the foam.

The inception of memory foam has a long tradition of bearing high standards as it was first developed for NASA and then used commercially, primarily in health institutions. For many years it was simply too expensive; the manufacturing process remained difficult and unreliable. Today, with our increased knowledge and technology, it has become more widely available. Buying American made memory foam is much safer than its imported counterparts because it is required to meet standardized quality control regulations. Most American memory foam is vacuum-produced, resulting in an even, quality consistency, and yielding a 100% pure visco-elastic foam without the questionable fillers used by other manufacturers.

We spend a third of our lives sleeping. For a 60 year old, that’s 20 years! Chinese memory foam may offer a product that carries an enticing discount, but there may be price to pay in quality and an even bigger cost to your health.

All-natural talalay latex vs. blended talalay latex

Thursday, June 9th, 2011

All-natural talalay latex vs. blended talalay latex and a look at the manufactures producing each:

All-Natural “Talalay Latex” is a very rare product, with only two manufacturers currently making true all-natural talalay latex. Dunlupillo and Latex International currently are the only two producers making all-natural talalay mattresses. So what is the difference between the two?

All-natural talalay latex is made from 100% latex rubber from rubber trees.
Blended talalaylatex can have a percentage of synthetic latex blended into the product.

What is ‘talalay’? Talalay is a process by which latex is formed into a mold. It is a high quality and consistent method of creating shaped latex, in this case into mattresses. The process itself:

  • Liquid rubber is whipped into foam and poured into a mold.
  • When closed the mold has rods that go through the foamed rubber.
  • A vacuum is placed on the mold, which removes air bubbles/pockets and distributes the liquid rubber evenly through the mold.
  • CO2 is run through the rods, freezing the foamed rubber and locking in the consistency.
  • Heat sent through the rods, providing even temperature and yielding a consistent latex cores without air pockets or uneven firmnesses.

Guide To Choosing Latex Beds

Friday, September 19th, 2008

Latex beds are becoming more and more popular. They alleviate some of the negative aspects of memory foam mattresses to provide the owner a more comfortable bed. Here is your personal guide for choosing your next latex bed.

First of all, you need to keep in mind that latex beds are going to be more expensive than some mattress and less expensive than others.
Latex mattresses are going to cost more than innerspring mattresses because they offer more comfort and support than an innerspring mattress does. You need to weigh carefully what is more important to you…the quality of the mattress or the cost. Latex mattresses are well worth their price.

Next, you need to think about size. What size mattress do you need? Are you going to be the only one sleeping on the bed? Or, is your husband or wife going to share the bed with you? Are you going to have to put the bed in a very small room? Or, is the room big enough to fit a King size bed comfortably? You don’t want to put a huge bed in a small room. Make sure that everyone who is going to be sleeping on the bed will fit on it and that it will fit in the room. In other words, if you and your husband are going to be sleeping on the bed, don’t get a twin size. If your room isn’t very big, don’t get a King size. Latex mattresses come in a variety of sizes so you can be sure to get the one that fits your needs.

You need to think about thickness next. The thickness of your mattress is a very important factor to consider. The thickness of your mattress relates directly to how comfortable you will be when you sleep. The thicker that mattress, the more support you will get. You will be more comfortable on a mattress that is completely supporting your body than you would be on a mattress that isn’t supporting you enough.

Lastly, you need to consider firmness. Do you want a firm mattress or a soft one? What does your spouse prefer? Make sure you get a mattress that is going to suit both of your needs. Getting a latex mattress isn’t going to do you any good if it isn’t comfortable. The firmness of the mattress relates also to the support to get. Get a mattress that is going to support you and be comfortable enough for you.

Choosing a latex bed may seem like a daunting task. Don’t let it be though. Make sure you know your price range. Think about size. Get the thickness right. Decide on the firmness. Take these four things into consideration when choosing your next latex mattress. You’ll end up with the perfect mattress for you.

Memory Foam Mattress Officially Evolves in the Latex Bed

Wednesday, September 17th, 2008

Memory Foam Mattress Officially Evolves in the Latex Bed, and understanding what it means.

Latex mattresses are beginning to evolve into new memory foam mattresses. These mattresses have been popular in Europe for years. However, the new trend is beginning to sweep across America. Americans have chosen memory foam mattresses as their “mattress of choice” for years now. But, latex mattresses are beginning to take over the lead.

Latex mattresses come in many different sizes, styles, levels of quality and different prices. Generally, latex mattresses are very expensive. A good quality latex mattress can cost upwards of $2,000. People love latex because the new latex technology alleviates some of the disadvantages of memory foam mattresses. A common complaint of memory foam is that it retains heat, thus causing the sleeper to become uncomfortable while asleep. Latex mattresses don’t have this problem because the air pocket holes actually work to cool down the mattress in the summer months and keep it warmer during winter.

Latex mattresses have been specially designed to provide all-around support. Memory foam mattresses tend to have a supportive base and semi-supportive upper layer. Latex mattresses provide support throughout the entire mattress, rather than allowing the sleeper to “sink in” to the mattress core. Allergies have also been a problem for people who sleep on a memory foam mattress. Memory foam mattresses are not hypoallergenic and can cause problems for people who are sensitive to allergies. Latex foam technology works to resist dust mites, mold and mildew and is naturally hypoallergenic.

Lastly, people love latex mattresses because they are “green.” People everywhere have joined the “Green” movement and are looking to support products that are also green products. Latex mattresses are made from all-natural materials and are biodegradable. All in all, latex mattresses are completely “eco-friendly.”

Memory foam mattresses have been extremely popular in America for the last several years, and for good reason. They offer good comfort and support. However, there have been some complaints about the memory foam mattress. Because of these complaints, manufacturers have been working to create a mattress that provides the comfort and support of memory foam, but without the disadvantages. They have solved the problem with latex mattress. Latex mattress offer more support and comfort than memory foam mattresses do. They also are more temperature friendly, hypoallergenic and are green friendly. If you are in the market for a new mattress, try a latex mattress. They are quite expensive but you’ll soon find out why they are becoming so popular in America.

6 Totally Amazing Benefits Of An All Natural Latex Mattress

Latex Pouring Explained, Dunlop vs. Talalay

Thursday, August 14th, 2008

I am often asked to define (or explain) what each method of latex pouring is: ie the Dunlap vs. Talalay methods, so I want to explore this option a little more for the Rocky Mountain Mattress Blog readers.

Latex comes in two different forms. Natural latex is composed of 95% natural rubber. Synthetic rubber is made of chemicals that are processed to form rubber. There are also two forms of latex pouring. The Dunlap method is more traditional and cost effective. The Talalay method provides the benefits of natural latex with chemicals.

Natural latex is a milky white liquid made of tiny rubber particles. The liquid is whipped with air. This whipping action forms the foam. The liquid is then formed into a mold where it is then heated. It is heated until it becomes a spring like rubber material. This method is fairly straight forward and is cheaper than the Talalay method.

The Talalay method requires more steps than the Dunlop method. It produces a more resilient form of latex and also a finer product. Soap and other curing products are mixed with raw latex. Computers are used during this process to check the temperature and viscosity of the mixture to ensure uniformity. Once the mixture is cooled, it is then whipped with air, similar to the Dunlop method. It is whipped until the consistency becomes similar to soft-serve vanilla ice cream. Then, the liquid is poured into molds. Iron rugs are moved up and down throughout the liquid while it hardens to form the open-cell structure.

The next step in the Talalay process requires a vacuum. The vacuum is used to remove air bubbles and make sure the mixture is spread evenly throughout the mold. Next, the latex is frozen. This prevents anything from settling at the bottom and ensures each particle is evenly mixed. Heat is used next to again make sure that no air is left in the foam. Then, the foam is taken out of the molds and washed at least five times. This removes any soap residue or other chemical agents. The foam is then dried. The final step is impact testing. Uneven pieces are removed and the final latex foam is cut into slabs and stored.

The Dunlop method of latex pouring uses natural latex. This method is a shorter process and is more inexpensive. The Talalay method combines natural latex and synthetic latex to create an open cell structure. This is a longer process and is more expensive. Both methods produce a good quality latex product that can then be used in latex mattresses.

All Natural Latex Pillow Product Review

Wednesday, April 23rd, 2008

About a month ago I purchased all natural latex pillows for both my wife and daughter because they kept talking about how badly they wanted to try them after seeing our “new green product line” here at Rocky Mountain Mattress. My wife already has some nice down pillows we purchased for her about a year ago, but really was captured by the look and feel of the all natural latex pillow. Here is a picture to get a better idea what the pillow looks like:

all natural latex pillow

Since giving them the pillows, I have had rave reviews from both my daughter and wife about how good their neck feels, and how soundly they sleep, and how fast they feel the pillow helps them fall asleep. They both agree that it is the most comfortable pillow they have ever laid their heads on. Normally my wife has to pile up two pillows to keep her neck where she wants it during the night, but with the latex pillow, it keeps her neck in a comfortable position, and it never loses its shape!

I am excited to be able offer the all natural latex pillow on Rocky Mountain Mattress as its an “eco-friendly” product, and is a great addition to our “green” product line.

Here Are The Main Differences In Latex and Memory Foam Products

Friday, March 28th, 2008

When looking for a new mattress, many consumers find themselves face to face with a tough question:

“Should I go with a temperature-sensitive memory foam mattress, or an all-natural latex mattress?”

The decision is really one of personal preference, as high-quality mattresses are available in both materials. To help take away some of the mystery surrounding the debate, though, here is a side-by-side comparison of natural latex mattresses and memory foam mattresses on several key points.

Support & Design

Memory foam is temperature sensitive, and conforms to your unique shape as the foam reacts to your body temperature. With high quality memory foams like those available from Rocky Mountain Mattress, this leads to a supportive, conforming experience. With quality memory foam mattresses, expect little to no motion transfer.

Natural latex also offers quality support, although the material is not conforming and heat sensitive. Natural latex mattresses are often a bit more firm than memory foam, and while motion transfer is still minimal, you may experience slightly more movement on a natural latex mattress.


Memory foam mattresses are designed to weather numerous compressions and years of use without losing their original shape. As long as consumers stay with high-quality, American made memory foam mattresses, you can expect 10-15 years of quality use out of a memory foam mattress set.

Natural latex mattresses are similarly designed to offer years and years of use. In fact, in many cases a high quality latex mattress can offer support and quality sleeping experiences for two decades or more.

Natural Features

While memory foam itself is not inherently hypo-allergenic and anti-microbial, many owners choose to purchase a mattress cover that does bring these features to the memory foam sleep system.

Natural latex, though, is safe for allergy suffers and prevents the growth of fungus and mold through its naturally occurring features.


Memory foam sleep systems are among the most customizable options for individuals to use. Memory foam can be cut to virtually any size and shape, and layers of support foam, foundation foam, and toppers – all in varying densities and heights to meet the consumer’s desire – can be designed to order.

Because latex is also a “foam” it too can be customized in terms of layering – and size and shape can also be determined by the customer.
