GOTS, OEKO-TEX, Down Pass: What Certificates Really Guarantee — and What They Don't

A look at the product pages of many bedding shops reveals a wall of seals – GOTS, OEKO-TEX, Down Pass, sometimes half a dozen at once. What each of these logos actually means is rarely explained. Yet they test completely different things: cultivation, harmful substances, animal welfare. Buying one certificate doesn't automatically buy you another. This article explains what GOTS, OEKO-TEX Standard 100, and Down Pass actually guarantee – and what they explicitly don't cover.

Why certificates on product pages often confuse more than they clarify

Many bedding shops display a row of seals beneath the product image without a word about what each one individually means. The effect: customers read "certified" and infer quality, sustainability, and safety all at once. In reality, each seal only covers a narrow slice – some test how the fiber was grown, others the level of harmful substances in the finished fabric, and others still the welfare of animals during the harvesting of filling material. A seal for freedom from harmful substances says nothing about organic cultivation, and an organic seal says nothing about manufacturing conditions in the sewing facility.

GOTS – what the standard actually checks

The Global Organic Textile Standard (GOTS) requires a minimum share of 70% organically grown fibers in the final product and accompanies the entire textile chain – from cotton cultivation through spinning, weaving, and dyeing to labeling. In addition to ecological criteria, GOTS also mandates minimum social standards along the supply chain, such as working hours and wages. GOTS is therefore a chain certificate: it certifies how the fiber was grown and how the fabric was processed – not primarily whether the finished fabric is free of residues, even though limits on chemical use are part of the standard.

OEKO-TEX Standard 100 – testing the finished product for harmful substances

OEKO-TEX Standard 100 takes a different approach: it tests the finished textile for a defined set of harmful substances – such as formaldehyde, heavy metals, pesticide residues, and allergenic dyes. The limit values are tiered by product class, with items for babies and toddlers required to meet stricter values than, say, home textiles. The seal says nothing about whether the cotton was grown organically or conventionally, and nothing about working conditions in production. It answers a single, clearly defined question: is there nothing in the finished fabric that would be considered a health concern according to the catalog of limit values.

Down Pass – proof of animal welfare for down and feather fillings

Down Pass certifies neither fibers nor chemicals, but rather the origin of down and feathers. The standard requires traceability back to the originating farm and excludes live-plucking as well as force-feeding. Independent audits along the supply chain – from the farm through the slaughterhouse and sorting facility to the finished product – are meant to ensure that these requirements are actually met. For bedding itself, Down Pass is generally irrelevant, since it contains no down filling; it becomes relevant for duvets and pillows with natural filling.

How to verify a certificate yourself

Every reputable certificate carries a license or certificate number that can be looked up in a public database maintained by the relevant standard – OEKO-TEX, for instance, offers an online directory for this purpose. If this number is missing from the product page, or cannot be matched, it's worth asking the retailer. A seal without a verifiable number is, in doubt, just a graphic.
