Down and feathers come from exactly the same place: a goose or a duck.
Feathers are the outer covering of the bird; they make it possible for the animal to fly, and they contain quills.
Down  lie beneath the protective feather covering of the bird. They typically come from the soft underside of the animal's belly and provide insulation to keep it warm. Down fibres are light and fluffy, and do not contain any quills. For this reason, pure down is considered to be one of the best fillings for your pillows. Their light and airy fibres make the pillow malleable, and ideal for a soft, supportive pillow. Down is perfectly conducive to a comfortable sleep and also provides excellent temperature control, adapting to your body's internal temperature. This will help keep you cool in the summer and warm in the winter.

Our products are designed by our team in United States and our manufacturing team in China meets the Business Social Compliance Initiative (BCSI) to ensure fair labor practices. Our products are shipped from our warehouse in Oakland, California, and some products are shipped from China.

All of our products are filled with goose down, fill power of down depends on the size of the down cluster. Well, geese are much bigger than ducks, so it makes sense that they have bigger down clusters,so we've always stuck with goose down, which is why it's so expensive.

A lot of sins can go into making a natural-filled pillow or duvet, including the way the feather and down is sourced. That’s why the best bed linen suppliers only work with partners that share their ethical values. At Seinest, we want our bedding benefits to extend way beyond a great night’s sleep.

All our sustainable goose down and feather bedding is responsibly sourced, independently
audited for compliance and supplied with the assurance that it has been sourced only as a by-product. Our suppliers are also monitored to ensure they practice the highest standards of care.

This is reflected in our accreditations. All Seinest cases and fills are Oeko-Tex Standard 100 certified, meaning they’re free from harmful substances. Our ethically sourced goose down duvets and pillows also hold the Downpass ® and RDS certifications, making them an ethical values products.You can check the authenticity of the certification by clicking on the link below..

The proportion of down and feathers for each product will be different. You can find the answer in the description column of the product page.

The smell you smell is natural to our down products - it just shows that our down has not been washed with special chemicals!

Our down has gone through 6-8 physical cleaning and drying processes, without adding any chemical detergent in the process, removing 99.9% of impurities and oil, and the cleanliness can reach 1000+.

To help get rid of that smell, we recommend airing out your product by taking it out of the packaging and placing it outside on a dry day for a few hours.

We never recommend washing our item at home in the washing machine, as this will damage the down clusters. If you'd like, you can dry clean the item, but keep in mind that this will shorten its lifespan.Wet down will have a greater odor, so be sure to keep the product dry and dry it regularly!

We have prepared detailed washing instructions for you, you can refer to the washing guide to solve this problem.

Your pillows and quilts may have accumulated sweat due to prolonged use, causing the down to clump together, as I said, the first step: put it in a dry and ventilated place for 2-3 days, or dry it in a dryer for 30 minutes Let the pillow dry well (remember not to expose it to the sun, which will yellow the cotton fabric). The second step is to wait until the pillow is dry, knead the pillow with both hands, fold it in half and beat it repeatedly, let the air fill the pillow, and the pillow will slowly return to a fluffy state.

We recommend drying your pillows and quilts once a month to help keep them fluffy and hygienic.

Fill Power, Down content，Fill Weight, and Product Weight are three key measurements to help understand the quality and warmth of our Down products.
Fill Power refers to the loft of the down used in the item or how voluminous (puffy) that down is. Loft is another way of measuring how many cubic inches of space one ounce of that down fill takes up. The loftier the down, the more space there is for air to get trapped, and therefore, the more insulated it is.An important factor that determines the filling power is the content of down. The higher the down content, the more fluffy the filling is.
Down content:We usually see different content standards such as 95%\90%\50%\30%, which refer to the proportion of pure down and feathers, feather silk and other impurities in the raw materials. For example, 95% of white goose down contains only 5% impurities and the rest is pure down. Of course, if it is 0%, it is called feather. The higher the ratio, the better the quality of down.
Fill Weight literally refers to the total weight of the down in the item. This is measured in grams and is a helpful variable in determining the warmth of an item.
Product Weight is the weight of the entire finished product, regardless of fill-weight and fill-power.

When you receive the compression pillow and quilt, it looks very collapsed, don't worry! As I said, rub the pillow with both hands, fold it in half and beat it repeatedly, let the air fill the pillow, and the pillow will slowly return to its fluffy state.

Let it sit for a night to let the filling slowly stretch out and achieve the best condition!

Most brands of pillows have a ball of filling stuffed into a cloth bag. The difference between us and other brands is that our pillow is like a hamburger structure, filled with soft goose down on the top and bottom layers, ensuring that the skin can enjoy the softness of the goose down.

The middle layer is filled with feathers for structural support, and the firm feathers maintain the shape of the pillow.
