  1. Barbara


    A truly cozy duvet that doesn’t feel heavy on my body but still warms me up instantly. It is super soft and cushy. I was extremely satisfied with the ordering process and even though I ordered a custom size the delivery was on time.

    I highly recommend it!

More Info & Care


The Organic Winter Wool Duvet

Our organic winter wool duvet is hypoallergenic, toxic-chemical free (no flame retardants, no Formaldehyde and other short-chain aldehydes, no heavy metals, no endocrine disruptors, no chlorinated benzenes, no ammonium compounds, no chlorinated paraffins), anti-bacterial, anti-microbial, anti-dustmite, temperature regulating, and certified safe enough for babies!

This 100% organic wool duvet regulates body temperature, because organic wool is creates a “microclimate”. It regulates body temperature and humidity. This relieves the body of thermal stress, and promotes deeper and more refreshing sleep.

What’s more, concerning hygiene, organic wool provides an environment too dry for dust mites to survive. So this means fewer dust mites in your bed and bedroom, and a more hygienic sleeping environment. So, you can rest easy, knowing you’re in the cleanest bed possible.

How to Care for the
Organic Winter Wool Duvet?

Your organic winter wool duvet is really fuss-free! Organic wool, because it is naturally anti-microbial, anti-bacterial, and anti-dustmite (when processed without chemicals), does not need to be washed. In fact, it shouldn’t be washed – that will ruin the integrity of the wool.

Simply dry clean on low, with no harsh chemicals.




"What is the best way to care for Organic Winter Wool Duvets?"
All 100% natural duvets – when actually 100% natural – shouldn’t be washed, and in reality, really can’t be washed. But that shouldn’t scare anyone away from making the swap to an organic and natural duvet!

Compared to synthetic duvets, a natural and organic duvet is still much more hygienic than a synthetic one – even without constant washes. Because synthetic materials (and even down & feathers) are very inviting to bacteria, mould and dustmite colonies, synthetic duvets need to be washed regularly.

And, not only does washing synthetics prove to be bad for the environment (see this article about micro-plastics & their effect on our planet), it is also bad for your health. Synthetic materials contain chemicals, which you rub against your skin and breathe while you sleep.

Dry clean delicately with no harsh chemicals, only when absolutely necessary.

"How is organic wool antibacterial & hypoallergenic?"
Our wool is 100% organic, chemical-free, very resistant against allergens. Indeed, organic wool is resistant to bacteria, microbes, dust mites and mould.

The reason why organic wool duvets are antibacterial and hypoallergenic, is because organic wool fibres are high-integrity (when processed without chemicals). And, they have microscopic “barbs” on their fibers, and contain a natural protein called lanolin, that also helps repel parasites.

What’s more, organic wool is able to absorb 2/3 of its in weight moisture, while still feeling completely dry! Organic wool creates a very dry “microclimate”, which makes it very difficult for allergens and bacteria to develop.

"Is your wool cruelty-free?"
At The House of Pillows, we’re only interested in using cozy, eco-friendly, ethical, healthy, and cruelty-free materials. And that’s why we use local organic farmers wool.

We source our organic wool from small, local farms, located near our Design Studio. The sheep raised on the farms, are cared for in a very humane way, and live healthy long lives! They are raised solely for their wool and for grazing the land, and not for the meat industry, making the wool cruelty-free!

We regularly visit the farms we work with, to control that their processes and standards remain high, and withhold the values we want to maintain.

Learn all about the difference between organic sheep and industrially raised sheep here.

“Where are your duvets made?”
All our organic duvets are skillfully handcrafted in our design studio, near the beautiful Julian Alps in Slovenia.

Every Sofia Duvet, is crafted by the House of Pillows team! The Sofia Duvets are made-to-order: that means the Sofia Duvet you place an order for, is made specially for you! Yeah… Just taking things “off the shelf” doesn’t feel right to us!

“What are the benefits of organic wool?”
Organic wool is a natural insulator – like down and feathers, only way more ethical, healthy and hygienic!

This 800g per square meter wool duvet, is perfect for keeping you perfectly nice and toasty during the winter time! It will regulate your temperature, so you’re not too not, or too cold.

What’s more, organic wool is also dustmite repellant, antibacterial, antimicrobial, and hypoallergenic. Organic wool is flame resistant, too – no artificial flame retardants needed!

“What are the benefits of organic cotton?”
Organic cotton is one of the best material for bedding! Indeed, organic cotton is very breathable and transmits moisture away from your skin. This allows you to feel fresh and dry all night. Organic cotton can absorb ⅕ of its weight in moisture, and still feel completely dry. Considering that our bodies release at least 300ml (around 16oz.) of body vapour per night while we sleep, organic cotton comes to the rescue to keep us comfortable and dry.

What’s more, organic cotton provides breathable insulation. It keeps you cool in the summer, and thermal insulation during the winter.

And unlike synthetics, organic cotton is hypoallergenic. Indeed, it doesn’t cause skin problems, or make preexisting skin problems (such as eczema, dermatitis) worse.

Our high thread count organic cotton, makes our Sofia Duvet incredibly soft, super breathable and very durable. It has high tensile strength, making it strong, durable and less likely to rip or tear.

“What do your certifications really mean?”
Certifications give us a higher level of certainty about what kind of materials & supply chains we’re supporting. We currently have the following three certifications.

Here is what they mean.

Oeko-Tex 100, Class 1

Oeko-Tex certifies that the materials have been scientifically tested in independent labs, and are certified safe for humans. Certified Class 1 products, are safe enough for babies and toddlers up to 3 years of age (learn more here). The labs test for all possible levels of toxicity. They make sure the materials don’t contain anything dangerous that would cause harm to a person coming in contact with them.

Oeko-Tex labs tests for over 200 toxic elements, including some that aren’t even required by state law to test.


GOTS is the Global Organic Textile Standard. The Global Organic Textile Standard (GOTS) is the worldwide leading textile processing standard for organic fibres, including ecological and social criteria. They are backed up by independent certification of the entire textile supply chain.

The goal of the standard is to have world-wide recognized requirements that ensure organic status of textiles, from harvesting of the raw materials, through environmentally and socially responsible manufacturing up to labelling to provide a credible assurance to the end consumer.


The International FAIRTRADE Certification Mark is an independent certification mark used in over 50 countries. It appears on products as an independent guarantee that a product is produced according to Fairtrade political standards.
