Our Certifications


OEKO-TEX certificate

The STANDARD 100 by OEKO-TEX® is a worldwide consistent, independent testing and certification system for textile products at all processing levels, as well as accessory materials used.
Since its introduction in 1992, the central focus has been the development of test criteria, limit values and test methods on a scientific basis. Its comprehensive and strict catalogue of measures specifies very low limit values for, among other things:

  • Formaldehyde
  • Heavy metals  (Complies with the US Consumer Product Safety Improvement Act (CPSIA) regarding lead.)
  • Pesticides
  • Aromatic hydrocarbons 

All Hamvay-Láng beddings (both the down and the textiles) are manufactured without the use of harmful substances and chemicals. 


The NOMITE mark indicates that a product is suitable for house-dust-mite-allergy sufferers: because down- and feather-filled products offer excellent thermal and climatic conditions for humans (rapid warming up when one is sleeping, rapid decrease in humidity when the bedding is aired), they provide a very poor habitat for house dust mites, which rely on high humidity to live.

The tight weave of the down- and feather-proof fabric acts as a barrier preventing the mites from passing through and offers, thus, additional protection. So that also those who suffer from house dust allergies or asthma can enjoy the natural comfort afforded by down and feather bedding. This has been demonstrated by scientific research.
