Textile labels carry a growing number of certification marks, and they cover quite different things. Two of them appear often enough on bedding to be worth understanding properly.

They Are Not the Same Claim

The most common confusion. One certifies how something was grown and made; the other certifies what is in the finished product.

A fabric can carry either, both or neither, and each answers a different question.

What Each Answers

Brands stating both certifications explicitly, of the kind at lanelinen.net, are making claims that can be verified through a certification database rather than asserted in marketing copy.

OEKO-TEX Standard 100

A testing standard for harmful substances in the finished textile. Certified products have been tested against limits for a long list of chemicals, including certain dyes, formaldehyde, heavy metals and pesticide residues.

The limits are stricter for products with more skin contact, and stricter again for items intended for babies and young children.

What it does not tell you is anything about how the cotton was farmed, about labour conditions, or about environmental impact during production. It is a product safety standard.

GOTS

The Global Organic Textile Standard covers the whole chain: organic fibre content, processing, chemical inputs, wastewater treatment and social criteria for workers.

It requires a minimum proportion of certified organic fibre and applies through every processing stage, with certification of each operator in the chain rather than a test of the end product.

It is the broader claim and correspondingly harder to obtain.

How to Check

Genuine certificates carry a number, and both schemes operate public databases where a certificate can be looked up.

A logo on a listing with no number behind it is worth less than one with a licence reference, and checking takes a minute.

What Certification Does Not Promise

It says nothing about softness, durability or how a fabric feels. Certified cotton can be short-staple and pill within a season.

The certifications and the quality indicators are independent, and both are worth checking.

Whether It Matters to You

For most adults, conventionally processed cotton from a reputable manufacturer causes no difficulty.

Where it matters more is for babies and young children, for anyone with sensitive skin or a contact allergy, and for anyone who cares about the environmental and labour conditions behind what they buy. Those are three different reasons and each points at a different certificate.

Wash It First

Regardless of certification, washing new textiles before use removes finishing residues and loose dye.
