Differences between the products

How do I choose between synthetic or natural? Is there a difference in comfort? What should I choose if I suffer from allergies?

In general, products made of feathers and down are known to be thermoregulating and provide warmth adapted to your different sleep cycles. These products are perfect for people who have a tendency to perspire. There is no known allergy to feathers, however as the filling is an organic material, it is more conducive to the development of mites. That is why we have developed the GSD solution, a patented concept whereby an anti-mite and anti-bacteria treatment is applied to the interior lining to curb the development of mites and bacteria.
Products filled with synthetic materials are commonly acknowledged as hypo-allergenic. Synthetic products, made from petroleum-based materials, are not thermoregulating and provide constant warmth. They are not recommended for people who have a tendency to perspire. Synthetic products are easier to care for as they take less time to dry than natural products.

What is the difference between duck down and goose down? Which is warmer? Which is fluffier?

In general, the growth of down clusters on animals depends on the way they are reared and breeding time. There are many differences between goose down and duck down. Duck down clusters are smaller than goose down clusters due to the size of the bird. As a consequence, products made using goose down are fluffier and warmer.

Why choose a square pillow rather than a rectangular one?

Choosing the shape of your pillow is very important. Support and comfort varies greatly depending on the shape of your pillow. A rectangular pillow does not offer the same support as a square one. A square pillow supports the head and neck and also the top of the shoulders. A rectangular pillow only supports the head and neck. Rectangular pillows are now more popular than the traditional bolster pillow. If you are looking to buy a bolster pillow, we can custom make it for you upon request.
