I want to purchase a down-and-feather-filled bedding product. What do I have to consider?

 
With the purchase of bedding products it is generally advised to look out for good quality articles.
 
In this regard, the different trademarks Daunasan® / Downafresh®, NOMITE® and KIS® Komfort Information System play an important part. These trademarks ensure that your top-quality bedding product meets various requirements.
 
The brands Daunasan® / Downafresh® refer to proper labelling and processing of the filling according to hygienic criteria, respectively. NOMITE® indicates that the duvet is suitable for house-dust-mite-allergy-sufferers.
 
The colour of down and feathers does not affect the quality, though. So-called “half-white“ or “grey“ down and feathers (including also brown ones) have the same usage properties as “white“ down and feathers. The premium down, the eiderduck down, has even a dark brown colour.
