All Natural Materials Mattresses | What “Natural” Really Means

All-natural-materials mattresses use latex, wool, and cotton; “organic” claims need third-party certification to be trustworthy.

Walk into any mattress store and half the showroom claims to be “natural” or “organic.” The reality is that those words describe different products with very different standards. An all-natural-materials mattress typically means one built from latex, wool, cotton, hemp, alpaca, or silk — and in the US market, “organic” is a claim that only has real meaning when a third-party certification backs it up.

Whether you’re avoiding polyurethane foam, chemical flame retardants, or fiberglass, this guide breaks down what the materials actually are, which certifications actually matter, and how to verify a brand’s claims before you spend thousands.

What Counts As An All Natural Materials Mattress?

A genuinely natural mattress is one where the primary construction materials come from plants or animals rather than petroleum. The most common components are organic cotton, wool, natural latex, hemp, silk, alpaca, and even coco fiber — each serving a different purpose in the build.

Latex forms the support and comfort layers, typically sourced as either Dunlop or Talalay. Wool acts as a natural fire barrier and temperature regulator, which is why it’s often found wrapped around the core. Cotton and hemp make up the outer cover and interior ticking, while small amounts of silk and alpaca add a softness premium brands use to justify higher prices.

Which Organic Certifications Can You Trust?

Certifications are the only reliable way to separate genuine organic mattresses from marketing copy, because a single organic fiber does not make the whole mattress organic. The finished product must carry certification for the claim to hold up.

Consumer Reports identifies GOTS and GOLS as the two mattress labels that most precisely meet stringent organic qualifications. These two certifications cover different parts of the build:

• GOTS — the key certification for organic textile components like cotton and wool. It requires at least 95% certified organic fibers for the “organic” label and applies to finished products, not just raw materials.
• GOLS — applies specifically to latex, requiring at least 95% certified organic latex or raw material.

Pay close attention to what a certification does NOT cover. OEKO-TEX, GREENGUARD Gold, and eco-INSTITUT are emissions-only labels that address chemical off-gassing, not organic content. CertiPUR-US applies only to polyurethane foam, so it has nothing to do with organic mattresses at all.

How Brands Position Their Natural Mattresses

Taking a look at how leading US brands describe their builds shows the range of what “natural” can mean in practice. Avocado Green Mattress, one of the most prominent certified-organic makers, uses GOLS-certified organic Dunlop latex, GOTS-certified wool and cotton, plus silk, Peruvian alpaca, and cocofiber in its construction. Avocado’s certification page states that its GOTS-certified finished products prohibit polyurethane foam, memory foam, chemical flame retardants, fiberglass, and chemical adhesives.

Birch takes a slightly different approach, emphasizing that its materials come from nature — including sustainably sheared wool and latex tapped directly from trees. Holy Lamb Organics sells “All Natural Mattresses” across three constructions: all-wool, innerspring, and natural-latex options.

How To Verify A Mattress Is Truly Organic

Verification comes down to three checks before you commit to a purchase. First, look for finished-product certification, not just a material claim — a mattress can use certified cotton in the cover while the core is synthetic. Second, confirm the certificate name matches the exact model or component you’re buying, not a similar product from the same brand. Third, cross-check the brand’s certification claim against the certifier’s public database or the certificate number printed on the tag.

Also read the spec sheet for what’s excluded. Some “natural” mattresses still contain synthetic components, adhesives, or foam unless the certification or materials list explicitly rules them out. A GOTS-certified finished product cannot contain polyurethane foam or chemical flame retardants, which is why that full-product certification matters more than any single material claim.

When you confirm those details, you know exactly what your money is buying — a mattress genuinely built from natural materials and certified as such, not one wearing a green label on top of a conventional build.
