OEKO-TEX certified bedding – what the certification means for you

You sleep seven or eight hours every night with your bedding right against your skin. Few textiles in your home have such close and prolonged skin contact — and few therefore deserve the same care when it comes to what they actually contain. This is where an OEKO-TEX certification becomes more than a symbol on the label. At Boe, all bedding is certified to OEKO-TEX STANDARD 100: both our crisp percale in the Ralph quality (200 thread count) and our soft, exclusive Supima cotton in Regency Lee (300 thread count). In this guide we explain, calmly and factually, what STANDARD 100 tests, why it matters for the skin — and, just as importantly, what the certification is not.
What is OEKO-TEX STANDARD 100?
OEKO-TEX STANDARD 100 is one of the world's most established certification systems for textiles tested for harmful substances. The core is simple: a textile carrying the label has been laboratory-tested against a list of over a thousand substances that may be harmful to health, and found safe for people to wear against the skin. The test covers not only the fabric itself but every component — thread, stitching and accessories such as buttons.
In other words, STANDARD 100 answers a very concrete question: is this product chemically safe for the person using it? It is a skin-safety and health assurance, not a marketing claim. You can read more directly from the certification body via OEKO-TEX's official page for STANDARD 100.
What is tested – and what does "over a thousand substances" mean?
The testing is based on strict limit values for substances regulated by law, but also goes further and includes substances that are not yet legally regulated but are nonetheless considered undesirable in skin-contact textiles. Among the parameters checked are:
- Banned azo dyes and certain allergenic dyes
- Formaldehyde and other free chemical residues from finishing processes
- Heavy metals such as lead, cadmium and nickel that can be released on skin contact
- Pesticide residues and chlorophenols
- A long list of further chemicals assessed on the basis of health risk
The crucial point is that the requirements tighten the more skin the textile meets. OEKO-TEX divides products into four classes according to the intensity of skin contact. Bedding belongs to product class II — textiles with direct and extensive skin contact — which means stricter limit values than for, say, curtains or outerwear. The very strictest class applies to products for babies. For you, this means the requirements for a certified sheet are not pulled out of thin air, but calibrated precisely for the way you actually use it: close to the skin, night after night.
Why this matters for the skin
Skin-close comfort is not only about how a fabric feels, but about what remains in the fibre after spinning, weaving and finishing. A beautiful sheet may still carry residues of process chemicals if it has not been tested and checked. STANDARD 100 is a way of knowing that this question has been asked — and answered by an independent laboratory.
This is especially relevant if you are attentive to what touches your skin during sleep, or simply want to be able to trust that a premium product is also clean on the inside. For those who want to go deeper into skin-friendly material choices, we have written more in our guide to allergy-friendly bedding. The certification does not replace good material choices — it confirms them.
This is what OEKO-TEX is not
It is just as important to be clear about the limits. STANDARD 100 is a test of harmful substances in the finished textile — not a broad sustainability or environmental certification. The label says nothing about water consumption, carbon emissions, working conditions, or whether the cotton is grown organically. It answers the question "is this product chemically safe to wear?", not the question "is it made in an environmentally sustainable way?".
OEKO-TEX has separate labels for the broader perspective — for example MADE IN GREEN, which also weighs in environmental and working conditions in the production chain. Confusing them is a common misconception. We prefer to be straight about what each label actually covers. Anyone who wants to read more about the difference can do so in OEKO-TEX's own overview of what the various labels mean.
How the certification connects with Boe's qualities
For us, OEKO-TEX STANDARD 100 is a natural baseline rather than a sales argument — a receipt that what we put on your bed has been tested for what cannot be seen. This applies to the entire range, whether you are drawn to the crisp or the soft.
Ralph – percale with a hotel feeling
Our Ralph is woven in percale with 200 thread count: a tight, cool and characteristically crisp weave. If you want to understand what makes percale so well loved, we have explained the technique in the article on the crisp hotel weave. Our entire percale collection is OEKO-TEX certified.
Regency Lee – Supima cotton with 300 thread count
For those who prefer a softer, more closed surface, Regency Lee is woven in Supima cotton with 300 thread count. Supima's extra-long fibres give a smooth and durable textile — do read more about why in our piece on Supima, one of the world's finest cottons. The entire Supima collection too carries STANDARD 100.

Frequently asked questions
Is Boe's bedding OEKO-TEX certified?
Yes. Boe's bedding is certified to OEKO-TEX STANDARD 100. This applies to both the percale quality Ralph (200 thread count) and the Supima quality Regency Lee (300 thread count).
What does OEKO-TEX STANDARD 100 mean in practice?
It means the textile — including threads and accessories — has been laboratory-tested against a list of over a thousand potentially harmful substances and found safe to wear against the skin. For bedding, which has direct skin contact, the stricter requirements of product class II apply.
Is OEKO-TEX the same as an environmental label?
No. STANDARD 100 is a test of harmful substances in the finished product, not a broad environmental or sustainability certification. It says nothing about water use, emissions or working conditions. For that perspective there are other OEKO-TEX labels, such as MADE IN GREEN.
Why does bedding have stricter requirements than other textiles?
Because the requirements in STANDARD 100 tighten the more skin the textile meets. Bedding belongs to product class II — direct skin contact over many hours — and therefore has lower permitted limit values than, for example, curtains or outerwear.
Does the certification make the bedding nicer to sleep in?
The certification is about what the textile contains, not how it feels. The feel comes from the weave and the fibre — percale's crisp coolness in Ralph or Supima's soft surface in Regency Lee. OEKO-TEX is the reassurance underneath; the choice of material is the comfort on top.
