CertiPUR-US and OEKO-TEX certify different parts of a mattress. CertiPUR-US tests the flexible polyurethane foam for content and low emissions. OEKO-TEX STANDARD 100 tests textiles, such as the cover and sheets, for harmful substances. They are complementary, not competing, so a well-certified bed may carry both, each covering a different component.
The core difference
| CertiPUR-US | OEKO-TEX STANDARD 100 | |
|---|---|---|
| What it certifies | Flexible polyurethane foam | Textiles and fabric components |
| What it checks | Content (no certain flame retardants, heavy metals, formaldehyde) and low VOC emissions | Tested for a wide list of harmful substances |
| Scope | The foam only | The tested textile components only |
| Origin | US foam program | International textile program |
| Organic? | No | No |
Why a mattress can carry both
A modern hybrid or foam mattress is made of different materials, and each certification covers a different one. CertiPUR-US speaks to the comfort and support foam, where off-gassing concerns usually originate. OEKO-TEX speaks to the cover fabric and any textiles, the parts closest to your skin. Seeing both is a good sign because it means two separate parts of the bed were independently screened. Neither, on its own, certifies the entire mattress.
Which should you prioritize
If the mattress is foam-heavy, CertiPUR-US on the foam is the more relevant signal. If you have skin sensitivities, the OEKO-TEX textile certification on the cover matters more. Ideally you want the right certification for the material you care about, not just any logo. Remember that neither is an organic certification; for that, see GOTS vs OEKO-TEX and our certifications explained guide.
Then choose the bed itself on comfort, support, and durability using our mattress buying guide and mattress types guide.
Frequently asked questions
Is CertiPUR-US or OEKO-TEX better?
Neither is better; they cover different materials. CertiPUR-US is for foam, OEKO-TEX is for textiles. The best mattresses often have the relevant certification for each part.
If a mattress has CertiPUR-US foam, is the cover safe too?
Not necessarily. CertiPUR-US only covers the foam. To know the cover was screened for harmful substances, look for OEKO-TEX STANDARD 100 on the textile.
Do either of these mean the mattress is organic?
No. Both are safety and emissions certifications, not organic certifications. For organic materials, look for GOTS for cotton and wool and GOLS for latex.
