Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

After receiving the down comforter from KNERST®, we were initially impressed by the quality of the material. The Oeko-Tex Standard 100 certification gave us the confidence that the comforter really does not contain any harmful chemicals. The filling weight of the comforter was comfortable and just right for a winter comforter – not too heavy, but still warming. The comforter proved to be extremely easy to care for, as promised. We could easily wash it at 40 degrees and even tumble dry it without the comforter losing its shape or quality. The even quilting not only ensured an attractive design, but also an even distribution of the feather and down filling, which made for a comfortable night’s sleep. While using the comforter, we noticed that the heat regulation was really very good. We always felt at a comfortable temperature, not too warm or too cold under the comforter. Overall, the KNERST® down comforter impressed us with its hygiene, pleasant filling weight, easy care, even quilting and excellent heat regulation. It is definitely an ideal choice for quality-conscious consumers who are looking for a high-quality and comfortable comforter. Thanks to Nomite certification, the down comforter is ideal for allergy sufferers.
