Frequently Asked Questions

Ferdown selects down and feathers from European countries, mainly France, Germany, Hungary and Poland.

The main advantage of European down over down of Asian origin lies in its larger size, fluffiness, thermal insulation capacity and lighter weight. In addition, it has the guarantee of having been subjected to a washing and sterilization process in accordance with the demanding European standards.

Down is the most suitable material to be used as a filling product in duvets. Its magnificent qualities as a thermo-insulating material, with very little weight, makes it unique above any other natural or synthetic material.

The structure and characteristics of feather make it a very suitable material for making pillows, which require a certain degree of support and flexoelasticity. As a filling for duvets, feather does not provide the insulation or lightness that down does.

In general, geese, being larger in size, will provide a greater volume of down than duck down. However, depending on the origin, ducks may provide better and larger down. An example of this, down from France, which offers higher volume levels than some geese. It is therefore more important to select a down with a high level of fill power than to focus on the species.

Some of the advantages are:

  • Greater thermal insulation with less weight.
  • Greater adaptability and compressibility.
  • Greater breathability.
  • Suitable for people allergic to dust mites.
  • Recommended for people suffering from asthma.
  • Longer durability and useful life, far superior to other warm bedding.
  • Washable.

Cuando la pluma está recién lavada, es normal que tenga un ligero y característico olor que desaparece en cuanto se airea. El nórdico de plumón, después de ser desempaquetado, necesitará respirar y en breve recuperará su esponjosidad y volumen natural.

Feather and down are not food for dust mites, and the temperature, light and humidity conditions are not the most suitable for their development. In addition, the high density of the fabric forms an effective barrier against dust mites.


Dr. Jürgens,H.W. of the University of Kiel, Germany, carried out a study of 192 tests on feather pillows with 78% negative for mites and 22% with such low levels of infestation that they were classified as negligible from an allergology point of view. Similar results were found for down duvets.

According to Kemp, T.J.’s publication in the British Medical Journal, polyester pillows contain higher levels of the mite allergen than feather pillows.

A dose-response relationship has been shown to exist between airborne beta-glucan levels and asthma symptoms: throat irritation, dry cough, itching, nasal irritation, fatigue and impaired lung and respiratory function.

According to Heyes J.’s study published in the Journal of Asthma, 46:1, 64-66, down-filled bedding has lower concentrations of beta-glucan than synthetic fillings.

The study was conducted by sampling duvets and pillows from households in Wellington, New Zealand. From these samples it was found that the beta-glucan level in synthetic pillows was two to three times higher than in down pillows, and in synthetic duvets the levels were seven to eight times higher than in down duvets.

Ferdown manufactures duvets with standard weights adapted to the different climates in our country.

In addition, for milder seasons such as spring or autumn, there are light duvets with less down. There are also those with a larger quantity than usual for those who desire.

Those who want to use their duvet at any time of the year can do so using our Combi models, which consist of two light units with different weights; depending on the time of the year, one, the other, or both can be used together by joining them with the hook-and-eye fasteners around the edges.

The down topper provides extra comfort; soft, fluffy and very comfortable. It fits snugly to the mattress with elastics at all four corners for an easy and comfortable fit.

The topper is an element of support and comfort, allows optimal moisture circulation and does not provide warmth.

In addition to the usual standard sizes, we manufacture duvets in any special size.

If required, we can also manufacture your duvet with the required amount of filling.

To keep your duvet in perfect condition, you just have to air it regularly. To preserve it, store it in a dry place in a cotton bag.

Do not use plastic bags or vacuum-packed bags. The duvet must “breathe” to preserve its properties.

Down-filled duvets and pillows should be washed with water and mild soap, at a temperature of no more than 30º.

It is essential to ensure that the product dries perfectly, ideally using a tumble dryer. If it is not dried correctly, the down may become caked, dull and even spoil. If, after the drying process, you find that it is not completely dry, repeat the process. Your duvet or pillow will then look as good as new.

The instructions for the topper are exactly the same as for the duvet, it should be washed with soap and water, always ensuring perfect drying. Due to its large size and weight, it may be more useful to go to an industrial laundry, with high-capacity washing machines and dryers.

Feather pillows: Place the shaken and fluffed pillow on a rigid surface, fold it in two parts -three if it is a double pillow-, compress it until all the air is out and release it. If the pillow still maintains an adequate degree of support, it will unfold and return to its original position. If it is unusable, it will remain folded.

Although most pillows look similar at first glance, there are major differences between them.

The most important is that a pillow filled with feather or down adapts to the shape of our cervical vertebrae without exerting pressure, while in other types of pillows, it is the person who has to adapt.

The durability and lifespan of our pillows is significantly superior to traditional fibre-filled pillows.
