What is synthetic latex?

The 30-second answer

Synthetic latex comes from crude oil, and Dunlop or Talalay names the way it is made, not its source. Ask for your mattress’s source and shares; one listed product has 40% natural and 60% synthetic latex. Synthetic latex tends to sleep warmer than natural latex; natural and blended latex cost more and are more durable.

Latex basics

Crude oil and latex mattress layers

Synthetic latex comes from crude oil. You may find Dunlop latex in a mattress’s comfort system or support core.

Crude-oil source

Synthetic latex starts as crude oil.

  • Natural rubber was scarce during wartime.
  • Ask the seller for your mattress’s source and percentages when you compare it.
  • One listed blend contains 40% natural and 60% synthetic latex.

Comfort and support layers

Dunlop latex may go in a mattress’s comfort system or support core.

  • A blended-latex comfort layer offers good pressure relief, especially for side sleepers.
  • A blended latex support layer gives your spine good support and limits motion elsewhere in the bed.

Natural, blended, or synthetic

The natural form starts mainly with rubber-tree sap; named blends list their shares. As you compare types, check the source and blend shares.

Natural latex

Natural latex typically contains at least 95% sap.

  • Sap-based latex may include other agents needed for curing.
  • Natural latex feels elastic and springy, and can conform to the body to reduce pressure-point stress.
  • One maker lab-tests foam samples to verify its claim of natural-latex-only content.

Blended latex

A typical mix contains 70% synthetic materials and 30% natural rubber, but the ratio varies by maker.

  • A listed Superior product has 40% natural and 60% synthetic.
  • An Embrace product has 30% natural and 70% synthetic latex, with a viscose supplement.

Synthetic latex

SBR is a synthetic latex material.

  • SBR can resist heat aging, abrasion, and softening.
  • Ask the seller for the source and percentages when comparing options.

Dunlop and Talalay describe the process

Dunlop and Talalay name manufacturing methods, not latex sources; either process can use natural, blended, or fully synthetic latex. Check the source and percentages before you choose.

  • Dunlop latex can be made in a mold or with a continuous-pour process.
  • Talalay manufacturing quickly freezes liquid latex, then heats it until it gels into a solid.
  • Vacuum-sealing the Talalay mold leaves latex particles more evenly spread than with Dunlop.
  • A Talalay product line can include pure natural latex and natural-synthetic blends.

Blends can lower mattress cost

When you compare prices, synthetic latex tends to cost much less than all-natural latex. Combining the two materials helps lower a mattress’s price. As a support layer, blended latex gives your spine good support and limits motion elsewhere in the bed. One listed product blend contains 40% natural and 60% synthetic latex. As a comfort layer, blended latex offers good pressure relief, especially for side sleepers. Ask for your mattress’s source and percentages before you compare products.

How synthetic latex may feel

Latex mattresses balance spring-back with contouring, while synthetic latex tends to sleep warmer than natural latex. Strong rubbery smells often occur in synthetic-latex layers; memory foam or polyfoam may make them worse.

  • SBR can resist softening. That may help a foam layer keep its feel.
  • Talalay has a more contouring feel that helps reduce motion transfer between partners.
  • Natural latex can conform to the body and reduce pressure-point stress.
  • If heat matters to you, check the product’s latex source.

How synthetic latex changes over time

Synthetic latex is less durable and less costly than natural or blended latex. Dunlop and Talalay both have a good record for durability. Dunlop may hold up a little better than Talalay.

  • Most beds with synthetic latex have a standard warranty.
  • When you shop, check whether your model’s warranty is 10 years.
  • Heat and UV exposure age foam. Yellow discoloration over time is normal.
  • If your mattress comes compressed in a box, unbox it soon.
  • Long compression can leave foam partly expanded.
  • Long compression can also cause permanent damage or reduce comfort and support.
  • On its own, synthetic latex may lose some springiness over time.

Check the latex content label

Ask for your mattress’s latex source and percentages before you rely on a logo. Check certification scope before you treat it as proof of latex content.

  • A typical blend is 70% synthetic and 30% natural rubber. The mix varies by maker.
  • One listed product has 40% natural and 60% synthetic.
  • Some companies use “natural latex” for a blend.
  • Companies use “all natural,” “pure natural,” or “100% natural” for latex made entirely from natural rubber.
  • One maker’s GOLS certification covers its finished toppers and mattresses.
  • CertiPUR-US covers flexible polyurethane foam, not latex foam.
  • The CertiPUR-US logo does not prove latex source or blend share.
  • If foam certification does not settle whether your model contains latex, ask the manufacturer.

What synthetic latex may offer

Synthetic latex allows a wide range of firmness options. Blended latex can relieve pressure in a comfort layer or support the spine in a support layer.

  • In a comfort layer, blended latex offers good pressure relief, especially for side sleepers.
  • In a support layer, blended latex gives good spine support. It also keeps motion from spreading.
  • If you want no synthetic latex, ask whether the maker lab-tests samples for a natural-only claim.
  • An Embrace product lists 30% natural and 70% synthetic latex, plus a viscose supplement.
  • A past synthetic-latex foam mattress listing showed $695, not a general market price.
  • That listing had a polyester cover and synthetic Dunlop latex with gel memory foam in its comfort layers.
  • Its support core used high-density foam.

Odor, latex allergy, and foam certification

CertiPUR-US covers flexible polyurethane foam, not latex foam. A mattress can also have a separate latex layer. With a natural-rubber latex allergy, your skin or moist areas react when latex touches them.

  • Severe latex allergy can affect breathing.
  • For one maker’s mattress, the smell fades most in the first week after you open it.
  • For one maker’s mattress, if you air it out, use a cool, dark room with good ventilation.
  • Household items made from synthetic latex typically do not cause allergy symptoms. Still, double-check the item.
  • Certified foam has low VOC emissions for indoor air.
  • VOC emissions are below 0.5 parts per million.

Questions & Sources

Quick answers about synthetic latex

Is synthetic latex just polyurethane foam?

Synthetic latex is made with SBR, a synthetic rubber from crude oil. Memory foam is a different material, a type of polyurethane foam that responds slowly. To check your mattress, ask the maker whether it contains latex.

Can synthetic latex be made with Dunlop or Talalay?

Yes, both processes can use synthetic latex. Dunlop and Talalay can also produce all-natural or blended latex. Ask the seller for your model’s source and percentages.

Does Talalay latex always contain synthetic material?

No, Talalay does not always use synthetic latex. A Natural product uses no synthetic latex. When you shop, ask for your product’s exact ratio, including 60% synthetic in a Superior blend.

Can you see the difference between natural and synthetic latex?

Looking at it does not settle it; the label wording does. One maker lab-tests its foam samples to verify its natural-latex content claim. Some manufacturers use “natural latex” for a blend. Companies use “all natural,” “pure natural,” or “100% natural” for latex made entirely from natural rubber. When you shop, check the source, ratio, and softness; these matter more than whether the process is Dunlop or Talalay.

Can a latex blend contain fillers?

One maker’s EcoInstitut certification includes content analysis on its latex foam. The analysis checks that the foam contains no synthetic latex or fillers. For your product, ask whether its latex foam had content analysis.
