Organic mattress certifications explained: what each label checks

Brand figures checked against each brand's own website on November 5, 2026. Standards checked against each standard's own website on November 7, 2026. How we check

Mattress certifications check different things. Some confirm organic content, some test chemical emissions, some screen ingredients, and one confirms there are no animal materials. A long list is only useful once you know which is which.

Below, each label is described in its own standard's words, checked on November 7, 2026, with the mattresses in our comparison that list it.

Every label, in one table

Definitions from each standard's own website, checked on November 7, 2026. Which mattresses list each label, from each brand's own website on November 5, 2026.
Label	What it checks	What the standard says	Listed by
GOLS	Organic content	Products made from organically grown natural rubber latex, with all raw materials meeting organic origin requirements apart from approved additional materials and accessories	All five
GOTS	Organic content	Textiles with at least 70% certified organic fibres, with every processing stage certified. The "Organic" grade requires at least 95%	PlushBeds (cotton and wool), Avocado (finished product), Naturepedic
GREENGUARD Gold	Emissions	Tested to meet chemical emissions limits. Gold sets even lower emission levels, with a low level of formaldehyde emissions specifically	All five
eco-INSTITUT	Emissions	A label for low pollutant and low emission indoor products, with emissions tested in a test chamber to ISO 16000. Mattresses and bedding are among the products tested	PlushBeds, Zenhaven
UL Formaldehyde Free	Emissions	Confirms the product does not emit formaldehyde or formaldehyde precursors over defined limits	Avocado, Naturepedic
OEKO-TEX Standard 100 Class I	Harmful substances	Every thread, button and accessory tested against a list of over 1,000 harmful substances. Class I covers products for babies and children up to 3 years and has the strictest limits	Avocado
MADE SAFE	Ingredients	Screens for known or probable carcinogens, endocrine disruptors, toxins, hazardous flame retardants, high risk pesticides, toxic solvents and harmful VOCs	Avocado, Naturepedic
EWG Verified	Not described	We could not read EWG's own definition when we checked, so we do not describe what it requires	Avocado, Naturepedic
PETA Approved Vegan	Animal materials	Identifies items made of vegan alternatives to animal derived materials	Naturepedic

PlushBeds also lists Control Union, the certification body that originally developed GOLS.

Read carefully

Four kinds of label

Organic content. GOLS and GOTS say how much of the latex or the textiles is certified organic, and trace it through the supply chain.

Emissions. GREENGUARD Gold, eco-INSTITUT and UL Formaldehyde Free test what a finished product releases into the air.

Harmful substances and ingredients. OEKO-TEX Standard 100 and MADE SAFE test for or screen out listed substances.

Animal materials. PETA Approved Vegan confirms vegan alternatives to animal derived materials.

None of these labels is a medical claim, and none says a mattress will improve your sleep or health. They describe materials and testing, nothing more.

Honest weaknessReturns open only after 30 days, and a return carries a $99 fee.

Avocado's argument is certification depth. The Green Mattress is certified organic at the finished product level under GOTS, and the brand lists five further standards for the whole mattress, including OEKO-TEX Standard 100 Class I, EWG Verified, MADE SAFE, GREENGUARD Gold and UL Formaldehyde Free. The latex is GOLS certified organic Dunlop over up to 1,379 individually wrapped coils in seven zones, needle tufted by hand in California.

The Medium feel carries 3 inches of latex at 11 inches high and is the brand's most popular. Plush carries 5 inches at 13 inches high and is positioned for side sleepers. Firm carries 2 inches at 11.5 inches. The trial is a full year, with a $99 return fee, and the warranty runs 25 years with the first 10 non prorated.

Naturepedic EOS Classic Organic Vegan, including vegan

100 night trial
25 year limited warranty
Five levels, Plush to Extra Firm

Who it is forA buyer who wants certified organic materials without wool or other animal products, or partners who want each side set differently.
Who it is not forAnyone for whom price comes first. Its Queen price at checking was the highest in our comparison.
Honest weaknessThe Queen price shown, $3,679.20, was a sale price, so expect it to move.

Most organic mattresses use wool as their flame barrier. This EOS Classic variant uses none, which makes it the pick for a buyer who wants certified organic materials without animal products. Fire protection comes from a plant based PLA batting, and the certifications on the brand's page include GOTS, GOLS, EWG Verified, MADE SAFE, PETA Approved Vegan, GREENGUARD Gold and UL Formaldehyde Free.

It is also the most adjustable mattress in our comparison. Five firmness levels, the option to set each side of the bed differently, and a modular build of a 3 inch organic latex comfort layer over an 8 inch encased coil layer, inside a zippered organic cotton encasement. Inside the 100 night trial, comfort layers can be exchanged free instead of returning the bed, under a 25 year limited warranty.

Who it is forAnyone who wants all latex and certified organic textiles, and the most latex for the money.
Who it is not forSomeone coming from a spring mattress who wants that familiar feel. The hybrids suit them better.
Honest weaknessThe paperwork. PlushBeds' own pages describe its trial and its warranty in more than one way, as the note under the table explains.

The Botanical Bliss is latex from top to bottom and certified organic in both its latex and its textiles. The build is six layers: a GOTS certified organic cotton cover, GOTS certified organic wool, a GOTS certified organic cotton panel, a natural latex comfort layer, a GOLS certified organic latex comfort layer on the 12 inch model, and a 6 inch GOLS certified organic latex support core. There are no coils and no synthetic foam layers to soften over time.

Certifications listed on the product page are GOLS, GOTS for both the cotton and the wool, GREENGUARD Gold, eco-INSTITUT and Control Union.
