How Are Latex Mattresses Made?
Latex is a natural material derived from the milky sap-like extract of a rubber tree. In the early 1900s, Dunlopillo was the first manufacturer to process latex into foam for use in mattresses and pillows.
Today, latex is either processed into Dunlop or Talalay Foam.
Latex sap is placed into a mold, whipped, and set to produce Dunlop. Talalay is poured into the mold in stages for more uniform consistency. It is often mixed with synthetic fillers, so it may not be ideal if you’re looking for an all-natural product. Because it takes longer to produce, Talalay foam can also be more expensive.
Not All Latex, However, Is Naturally Sourced.
Some manufacturers use entirely synthetic materials. While these models can be less expensive, they may not be of the same caliber.
Synthetic latex is typically made from plastic known as styrene-butadiene rubber (SBR), which is also used in tires and artificial turf. It is considered safe, but it is not as durable as natural latex. While generally regarded as harmless, off-gassing can cause reactions in some people and is most prevalent in synthetic products.
Some latex mattresses contain a blend of natural latex and SBR. While they last longer than purely synthetic latex mattresses, they are not as durable or comfortable as all-natural models.
Natural latex mattresses are a bit more expensive than their synthetic or synthetic-blend counterparts, but they have a lower carbon footprint and longer lifespan. They also tend to provide superior support and comfort and are less likely to cause respiratory irritation from off-gassing.
Savvy manufacturers are starting to use multiple layers made with different materials to give consumers the best of all worlds. You can find mattresses that combine latex and memory foam, such as hybrid mattresses with one or more comfort layers of latex foam atop a coil core.
Pros and Cons of Latex Mattresses
Pros of Latex Mattresses
Latex mattresses cradle the body with gentle contouring, similar to memory foam, that relieves pressure and cushions pressure points. However, unlike memory foam, it is buoyant and can bounce back without leaving impressions and indentations. Latex’s flexible support also helps maintain spinal neutrality. These mattresses are particularly beneficial for people with chronic pain and musculoskeletal issues.
Natural latex mattresses can last for 12 to 20 years. That’s longer than most foam mattresses and significantly longer than most innerspring products. Rubber is naturally resilient and retains its shape immediately after compression, preventing the core from recessing excessively over time.
Natural latex is hypoallergenic and free of harmful substances. It is also naturally antimicrobial. It will not accumulate microorganisms, such as bacteria, viruses, and fungi, that could cause allergies and other issues. Latex also tends to maintain a consistently cool temperature conducive to better sleep, especially if you’re a naturally hot sleeper.
Natural latex is a sustainable material. It is harvested from just beneath the bark of a rubber tree, and the process does not damage the tree or require felling. Most rubber trees can recuperate quickly and continue producing sap for about 25 years. Latex is also biodegradable, so used mattresses will not sit endlessly in a landfill.
Latex is highly customizable. Manufacturers can design a mattress specifically for your body, with varying levels to prevent pressure on the shoulders and hips. More personalization means people with larger bodies (who may find mattress shopping difficult) can find a number of great options. Latex beds also come in various firmness levels, from extra soft to extra firm, whereas some materials only come with a few firmness options.
Cons of Latex Mattresses
Natural latex is dense and heavier than many materials. A queen-size mattress can weigh as much as 130 pounds and may be difficult to flip, rotate, or move.
Latex mattresses, especially those made with all-natural materials, can be expensive. Prices can vary widely depending on the brand and product, but some latex mattresses cost as much as $3,000.
What to Look for in a Latex Mattress
While it may be more expensive, it’s worthwhile to consider purchasing an all-natural latex mattress. These versions tend to be more supportive, responsive, and comfortable and last longer than those made with synthetic material. If you can’t afford an organic latex mattress, you can settle for one with a blend of synthetic and natural latex.
If eco-consciousness is a priority, look for a certified product by the Global Organic Textile Standard (GOTS), Global Organic Latex Standard (GOLS), eco-Institut, OEKO-TEX, or similar authority. These certifications ensure the product is ethically and sustainably sourced and manufactured.
