How to choose an organic mattress: GOTS, GOLS and flame-retardant rules

The USDA regulates the word "organic" for farm products. A mattress is a manufactured product, so the claim usually rests on the raw materials inside it: cotton, wool and natural rubber latex that were grown on certified organic farms or plantations.

The USDA's labeling guidance for textiles is specific. A product may not state or imply that the finished item is USDA organic, or use the USDA seal, unless the finished product itself is certified to the USDA organic regulations. The same guidance says textiles that meet the Global Organic Textile Standard may be sold as organic in the United States.

That is why the certifications below matter more than the word on the law tag. They are also the standard we use for the picks on our organic mattresses page.

Three marks appear most often on mattresses sold as organic. Each one answers a different question, and none of them answers all three.

The most common gap is scope. A brand can truthfully say it uses GOTS certified organic cotton in the cover while the foam, batting and adhesives sit outside any organic standard. These steps close the gap.

Every mattress sold in the United States has to meet two Consumer Product Safety Commission standards, whatever it is made of. That includes adult, youth and crib mattresses and futons.

The first, 16 CFR Part 1632, tests resistance to a lighted cigarette. A test location passes if the char length is not more than 2 inches in any direction from the cigarette. This standard also applies to mattress pads.

The second, 16 CFR Part 1633, is an open-flame test. Over a 30 minute test, the peak rate of heat release must not exceed 200 kilowatts, and the total heat release must not exceed 15 megajoules in the first 10 minutes. Mattress pads, mattress toppers and pillows are excluded from this one.

A mattress that meets Part 1633 carries a permanent label with the manufacturer's details and the month and year of manufacture. If a mattress has no such label, do not buy it.

The rules do not settle this for you. Parts 1632 and 1633 set results a mattress must achieve in a test. They do not name a chemical or a material that has to be used to get there.

The regulation itself shows there is more than one route. It requires manufacturers to keep records of "any flame retardant treatments and/or inherently flame resistant fibers or other materials" used in mattress components. So a maker may rely on a treatment, on a fiber or barrier layer that resists flame by its nature, or on both.

The practical step is to ask the manufacturer one direct question: what material allows this mattress to pass 16 CFR Part 1633, and is any flame retardant chemical added? A company that has done the testing can answer in a sentence.

The same certifications apply, with the same scope question. An organic mattress topper made of latex should name GOLS for the latex and GOTS for any cotton or wool cover. For organic pillows, ask whether the certificate covers the fill, the casing or both.

Crib mattresses fall under both federal flammability standards. They also raise safe sleep questions that have nothing to do with organic content, and our page on organic crib mattresses covers those.

If you see OEKO-TEX on a mattress or its cover, read it as a test for harmful substances, not as an organic claim. We compare the two in GOTS vs OEKO-TEX.
