Organic sleep certifications: what GOLS, GOTS and the rest actually mean

Which part of the bed each covers

The single most useful idea here is that no certification covers the whole mattress. Each one applies to a specific material or property, so a genuinely organic bed carries several at once.

The certifications, one by one

GOLS (Global Organic Latex Standard). This certifies the latex, and it sets a real bar: at least 95% certified organic latex content. It is issued by bodies such as Control Union. When we checked the PlushBeds latex certificate, it was GOLS version 3.0, covering latex mattresses, pillows and toppers made with over 95% certified organic latex. GOLS does not cover the cover or any foam, only the latex.

GOTS (Global Organic Textile Standard). This certifies the textiles, an organic cotton cover or organic wool, and adds processing and social criteria on top of organic fibre content. A latex bed that is GOLS certified but not GOTS certified has organic latex under a cover that is not certified organic. We have read the PlushBeds textile certificate, and the section below sets out what it says.

OEKO-TEX Standard 100. Not an organic standard at all. It tests a textile for a long list of harmful substances against defined limit values, component by component. It answers "was this fabric tested for harmful substances?", not "is it organic?"

GreenGuard Gold (UL). This certifies low chemical emissions, not organic content. Issued by UL, it holds the finished product to limits for VOCs and formaldehyde for indoor air quality.

The PlushBeds Botanical Bliss certificate we read is a UL GreenGuard Gold certificate under UL 2818, with limits such as formaldehyde at or below 7.3 parts per billion and total VOCs at or below 0.22 milligrams per cubic metre. It is about what the product releases into the air, nothing more.

eco-INSTITUT. A German testing institute whose certification, like GreenGuard, focuses on emissions and harmful substances. Seeing it alongside GreenGuard means two independent labs looked at the product's emissions.

CertiPUR-US. This one is for polyurethane foam, so it is what to look for on a memory foam topper or mattress, not on latex. Run by the Alliance for Flexible Polyurethane Foam, it certifies that the foam is made without certain chemicals, such as ozone depleters, specified flame retardants, and formaldehyde, and that it is low-VOC. Our Sleepyhead topper review is an example of a foam product that carries it.

One thing about CertiPUR-US is worth saying plainly, because we found it by opening the document rather than looking at the badge. The paperwork behind a brand's CertiPUR-US mark is often not a certificate at all.

In the PlushBeds set we hold, it is a letter from the Alliance for Flexible Polyurethane Foam, CertiPUR-US program, dated 27 February 2014 and signed by Robert Duffy, Executive Director, granting permission to use the CertiPUR-US program logo, mark and name in association with products containing certified flexible polyurethane foam.

It carries no certificate number, no product list and no expiry date, and the permission is conditional: it holds only while covered products use certified foam from a registered producer in good standing, and the programme reserves the right to withdraw it.

That is a licence to use a mark, not a test result for a particular mattress. It does not make the foam claim false, because the foam itself is certified at the producer, but it does mean the badge and a lab report are two different things, and only one of them was in the folder.

The quick comparison

The GOTS certificate behind the organic cotton and wool, read field by field

Most pages that mention GOTS explain the standard. This one shows the document. We read the current PlushBeds textile certificate in full on 9 August 2026, all three pages including both appendices, and these are its fields.

Two things in there are worth more than the number. The first is the products appendix, which is the page nobody reads. It does not say "organic textiles" in the abstract.

It lists the exact material compositions carrying the Organic label grade: mattresses in 100% organic cotton; mattresses in 33.3% organic cotton with 66.7% organic wool; mattresses in 66.5% organic wool with 33.5% organic cotton; and bed linen and bed sheets in 100% organic cotton.

So the certificate covers wool as well as cotton, and it covers bed linen as well as mattress covers.

That answers a question this site had already published without an answer. Our Eco Bliss review points out that the brand's certification block advertises organic wool while that particular mattress has a cover described as wool-free, which makes the badge wall hard to shop.

The certificate resolves it: the organic wool claim is real and certified, for the mattress builds that contain wool. The Eco Bliss is not one of them. The badge is true and the product in front of you may still not be the one it describes, which is the whole argument of this page in a single example.

The second thing is a limit the certificate prints on itself, and we would rather quote it than paraphrase it: "This Scope Certificate provides no proof that any goods delivered by its holder are GOTS certified. Proof of GOTS certification of goods delivered is provided by a valid Transaction Certificate (TC) covering them."

In plain terms, a scope certificate says this company was audited and found in conformity for these product categories. It does not say the item in your cart shipped under it. That proof is a separate document, a transaction certificate, issued per consignment.

We have not been shown one and have not asked for one, so the strongest honest sentence we can write stops at the company and the categories. If you have ever wondered why a brand can hold a genuine certificate while a specific product still needs checking, that sentence is why, and the certifying body wrote it, not us.

We have done this once before with the other half of an organic bed. The latex side is covered in the GOLS certificate, read the same way, and the two together are what "certified organic mattress" actually rests on: one document for the latex inside, one for the fabric outside, each with its own scope and its own expiry date.

The trap: read the scope

The most common way "organic" claims mislead is scope. A product can honestly say "GOLS-certified organic latex" while its cover is not certified organic, or carry a certification on one product line that a shopper assumes applies to another. A real certificate always states what it covers: which materials, which products, and until when.

That is why, when we call a product certified, we mean we have read the certificate and checked its scope, not that we saw a badge on a page.

A worked example of the scope trap, on a product rather than a certificate: a wool mattress protector sold alongside these certified organic beds carries a Woolmark mark on its wool and an OEKO-TEX test on its cotton, and neither of those certifies organic content. The marks are genuine, the GOTS certificate above does not reach that product, and the difference is invisible unless you read the wording.

If you want to see that done rather than described, we published one: the GOLS certificate behind the PlushBeds organic latex range, read field by field, with its number, its certifying body, the product categories in its annex, the company it is issued to, and the date it expires. It also sets out the four things to check on any brand's certificate.

Among the products we cover, the PlushBeds organic mattresses, the Botanical Bliss, Luxury Bliss and Natural Bliss and Royal Bliss, and the organic latex topper carry GOLS for the latex, GOTS for the cotton and wool, and GreenGuard Gold and eco-INSTITUT for emissions, which is the full stack for an organic latex bed. How we check claims like these is set out in our method.

One distinction worth keeping separate from all of this: a certification tells you about the material and its processing, not about how the latex layer was moulded. Dunlop and Talalay are curing processes, and either can be certified organic or not certified at all.

Our guide to Dunlop vs Talalay covers what that difference does and does not mean, so you can read the two claims independently rather than treating one as a proxy for the other.
