Anyone looking into certifications in sleep products will quickly encounter various quality marks and certifications. When purchasing a mattress, duvet, pillow, or other sleep product, you will come across GOTS, OEKO-TEX, GOLS, and terms like “eco,” “natural,” and “sustainable.”
This is precisely why certifications are important. They can help to better evaluate claims about materials, production, and harmful substances. However, a certification only says something about what falls within the relevant standard. For example, a certification mark on the ticking of a mattress does not automatically mean that the entire core is also certified.
In this guide, you will read about what the most important certifications for natural sleep products mean, what they are used for, and how to avoid confusing a certification mark with a general quality or health claim.
Why are certifications important for sleep products?
A sleep product is used intensively and for a long time. Your skin comes into contact with bedding, and a pillow lies close to your face for hours. Furthermore, a mattress and topper consist of multiple materials and layers.
Certifications can therefore provide additional information about, for example:
- the origin of certain materials;
- the processing of organic fibers;
- the use of certain chemicals;
- the composition of latex;
- requirements that a production process must meet.
The most important thing, however, is that you always look at exactly what is certified. A certification can apply to a raw material, a material, a component of a product, or the entire product.
The most important certifications in sleep products
Not every certification mark has the same function. One certification is primarily about organic raw materials and processing, while another looks specifically at harmful substances or the properties of a specific material.
For natural sleep products, GOTS, OEKO-TEX, and GOLS are particularly relevant certifications to know.
GOTS: for organic textiles
GOTS stands for Global Organic Textile Standard. It is an international standard for textiles consisting of certified organic fibers. The standard sets requirements for organic fibers, processing, and various aspects of production.
For sleep products, GOTS is especially relevant for materials such as organic cotton and organic wool. You may therefore encounter the certification mark on, for example:
- duvets;
- pillows;
- mattress ticking;
- topper covers;
- baby bedding;
- fitted sheets and other bed textiles.
GOTS is particularly interesting when you not only want to know if a fiber is organic, but also want to know more about the processing and production of the textile.
What does GOTS not automatically imply?
A GOTS certification of a component does not automatically mean that the entire sleep product is GOTS-certified.
For a mattress, for example, the ticking or a specific textile layer may be certified, while other components fall under different standards.
Therefore, always read the product information and check whether it concerns GOTS-certified material or a GOTS-certified finished product.
OEKO-TEX: tested for harmful substances
OEKO-TEX STANDARD 100 has a different function than GOTS. This certification focuses on testing textiles and components for harmful substances and sets limit values for them.
That makes OEKO-TEX relevant for many sleep products that come into direct contact with the skin, such as:
- pillows;
- duvets;
- fitted sheets;
- mattress covers;
- baby and children’s textiles.
OEKO-TEX is not the same as organic
This is an important distinction.
A synthetic material, for example, can meet the requirements of OEKO-TEX STANDARD 100. The certification therefore does not automatically mean that a product is organic, natural, or free from all synthetic materials.
OEKO-TEX is particularly relevant when you want to know if a certified product or component meets the relevant requirements for harmful substances. If you also want natural or organic materials, you should look at the material composition and other relevant certifications.
GOLS: for organic natural latex
GOLS stands for Global Organic Latex Standard. This standard is specifically focused on organic natural latex and latex products.
For sleep products, GOLS is therefore particularly interesting for:
- natural latex mattresses;
- natural latex toppers;
- natural latex pillows;
- other products with a latex component.
Why GOLS is relevant for mattresses
The term “natural latex” on its own does not tell you how much natural latex a product contains or how the latex was produced. GOLS therefore provides an additional way to evaluate claims regarding organic latex.
Here too, the rule applies: look at exactly what is certified. A mattress may, for example, contain a GOLS-certified latex layer without every other layer of the mattress falling under GOLS.

Certification versus “natural,” “organic,” and “eco”
One of the most important lessons in evaluating sleep products is that marketing terms and certifications are not the same thing.
Natural basically describes the nature of a material but is not a substitute for a specific certification.
Organic refers to production according to certain organic standards, but here too it is important to know which raw material or component is actually certified.
OEKO-TEX primarily relates to testing for harmful substances and does not automatically mean that a product is organic.
GOTS is focused on organic textiles and their processing within the scope of the standard.
GOLS is specifically focused on organic latex.
So one certification mark is not simply “better” than another. They answer different questions.
What exactly is certified?
This is perhaps the most important question you can ask yourself when you see a certification mark on a product page.
Question:
- Is the entire product certified?
- Or is only one material certified?
- Which layer or component falls under the certification?
- Which requirements are exactly being checked?
- Is the certification still valid?
- Can the provider show the certificate or certificate number?
That is especially important for mattresses and toppers, as these can consist of multiple layers.
For example, a certified cotton ticking does not automatically make the entire mattress construction certified.
Which certification fits which sleep product?
Not every sleep product needs the same certification. The relevance depends on the materials and on what you find important.
Mattress
With a mattress, it is wise to look at different components: the ticking, the fillings, the latex layers, and any other materials.
GOTS can be relevant for organic textile layers, while GOLS can be relevant when organic natural latex is used. Other certifications can provide information about harmful substances or the properties of specific materials.
Therefore, look at the complete layer construction and not just at one certification mark.
Pillow
With a pillow, the filling and the ticking are important. Depending on the material, GOTS, OEKO-TEX, or other material-oriented certifications may be relevant.
However, the certification does not tell you if the pillow has the right height or support. For that, you also need to look at your sleeping position and personal preference.
Duvet and bedding
For duvets, fitted sheets, and other bed textiles, GOTS and OEKO-TEX are often relevant certifications to consider, depending on the materials used and the manufacturer’s claims.
Baby bedding
For baby and children’s products, it can be extra important to look closely at materials and certification.
GOTS and OEKO-TEX can be relevant starting points here, depending on the material and the specific product.

Certifications and allergies
Those who are sensitive to certain materials or substances may place extra value on certifications. Still, it is important not to conclude that a certification mark automatically means a product is suitable for every allergy or sensitivity.
Always look at the full composition and the specific properties of the product.
A certification can provide information about, for example, harmful substances or organic production, but it does not automatically say anything about every possible allergic reaction or personal sensitivity.

How to avoid being misled by a certification mark
A certification mark can be valuable, but the logo alone does not tell the whole story.
Therefore, use this simple checklist:
- Look for the exact name of the certification mark. “Eco” or “green” is not a substitute for a concrete certification.
- Check what is certified. Is it a raw material, a material, a component, or the entire product?
- Read the product information. Look at the full material composition.
- Ask for proof. A reliable provider should be able to explain which certification applies.
- Look for the certificate number if available. This allows you to better verify the claim.
- Do not confuse different certification marks with each other. GOTS, GOLS, and OEKO-TEX each have a different function.
Which certifications do you really need?
You don’t need to look for a product with every possible certification mark.
The best certification depends on what you want to know.
- Do you want organic textile fibers and controlled processing? Then look for GOTS.
- Do you want to know if textiles have been tested for harmful substances? Then look for OEKO-TEX STANDARD 100.
- Do you want to evaluate organically certified natural latex? Then look for GOLS.
Then comes the second question: does the product itself suit me?
A certified pillow can still be too high. A certified duvet can be too warm or too light for you. And a certified mattress may not suit your body in terms of firmness.
Certification therefore primarily helps in evaluating what you are buying. Comfort and suitability then determine if the product is also the right choice for you.
Certifications help you choose more consciously
A certification mark is no guarantee that a sleep product is perfect in every respect. It is primarily a way to make certain claims more verifiable.
The most important step is therefore not to collect as many logos as possible, but to understand what each certification mark actually means.
GOTS, OEKO-TEX, and GOLS answer different questions about materials, processing, harmful substances, or organic latex. By understanding those differences, you can better evaluate product claims and compare them more effectively.
Do you want to make a conscious choice for natural sleep products? Start with the material composition, then look at the relevant certifications, and then evaluate whether the product fits your body, sleep habits, and preferences.
This way, a certification mark doesn’t become a marketing logo you blindly trust, but a tool that helps you choose a sleep product with more knowledge and confidence.
