Features We Know You'll Love

Got Questions? We’ve Got Answers

When it comes to luxury, it’s all about the details — and that starts with the down. Down insulates by creating air gaps between two temperature zones, effectively trapping warmth and keeping you cozy. But not all down is created equal. The key to exceptional insulation lies in the loft factor, or "fill power," which measures how much the down can expand to create those critical air gaps.

To deliver the perfect balance of warmth and softness, we use only the finest down with a loft factor of 700 fill power — well above the industry standard of 500. This premium fill provides optimal insulation while offering the signature soft rebound that luxury products are known for. After testing thousands of customer experiences, we've ensured this loft factor creates a duvet that not only keeps you warm but feels truly indulgent. At Roomie Design, we're committed to offering you the best in comfort and quality for a five-star sleep experience every night.

When it comes to durability, the key lies in the quality of the down itself. 100% down, unlike down-feather blends, doesn’t have the added weight of feathers, making it naturally more resilient and long-lasting. The oil content in the down plays a crucial role in maintaining its integrity. A balanced oil content, between 0.2% and 0.7%, ensures that the down retains its loft and durability without becoming overly greasy, which could cause odors.

To keep your 100% down duvet in optimal condition, fluff it regularly to maintain its loft and warmth. Additionally, promptly drying any liquid spills will prevent the down from losing its softness and insulation properties. With proper care, your 100% down duvet will provide luxurious comfort and long-lasting performance for years.

At Roomie Design, we handpick high-fill power down to create a duvet that offers top-tier comfort and loft. Each duvet is filled to order, ensuring freshness with no time spent sitting in a warehouse.

We use a specialized washing process to maintain the ideal balance of natural oils in the down. This enhances durability and prevents any unpleasant odors, ensuring your duvet is both long-lasting and fresh.

Experience premium down that combines luxury, durability, and freshness for a perfect night’s sleep.

Feathers have a hard quill shaft and are less efficient at trapping heat, while down is the soft, fluffy undercoat of the bird, known for its superior insulation properties. Down is the best natural insulator per ounce, providing more warmth and comfort than both feathers and synthetic fills.

Down is one of the best natural insulators, offering unmatched warmth while remaining incredibly lightweight. Its unique softness and breathability make it a favorite in the luxury market, providing an indulgent, cloud-like feel that enhances your sleep experience. Whether you’re seeking warmth in the winter or coolness in the summer, down adapts to your body’s needs for year-round comfort.

Absolutely amazing! I treated myself to this goose down duvet, and it’s worth every penny. It feels like being wrapped in a soft cloud—so warm and inviting. The extra-large size is perfect for my California King, fully covering the bed with a luxurious drape. It's cozy yet lightweight, making every night feel like a special treat. I can’t believe I found this quality at such a great price—highly recommend!

This fluffed right up out of the package. It is lightweight but full enough to be comfy and warm. The fabric is soft and luxurious to the touch. Hopefully it will hold in the down filling over time.

Nice, soft, fluffy ☁️💛

I was looking for a comforter that I could use year round and finally found it! This is lightweight but still keeps you warm. I tend to get hot when sleeping and this comforter is heaven - not too hot, as all my others have been.

This comforter is incredibly soft inside and out. It has the perfect weight, and equally the perfect amount of 'fluff' that you need in a down alternative comforter. It's price is unbelievable for the quality. Machine washable makes it easy to own and take care of. You'll want one for every room. Also would make a great gift.

Top marks for the gooses.

Really light and warm. Better than I thought and looks good too. No need for a bedspread. Impressed.

Wide duvet in color

I’ve been looking a long time for just that.. a wide soft duvet comforter that did not need a cover and hung long on sides of king bed. It does just that, though I’d love even wider! Only reason I didn’t give 5 stars is the color says gray, and looked gray in photo but it is more violet.

Sizing does not match

Im disappointment I got the duvet and duvet cover to match and the duvet cover is swimming in the duvet so it looks stupid. Spent over 500 euro on this and I’m sickened to say the least

wonderful cosy duvet

The duvet is very comfortable and warm
It is also a lovely colour

Exceptional Quality Duvet

Excellent quality and fits perfectly in the duvet cover without moving which is what was happening with other super king duvets. Very happy

Highly recommend this fantastic duvet

The signature 100% goose down duvet is superb. It is light but exceptionally warm but does not make me sweat like my previous feather duvet. It is very soft and comfortable and moulds to your form keeping out drafts. Great value for money. Highly recommend.

Great well constructed warm duvet

This is a well made duvet that feels great and is warm. I dont need my electric blanket anymore. Considering how many hours are spent in bed, this is well worthe the price

Perfect

It was better than we expected we are delighted

As advertised

It’s beautiful, comfortable, and cozy

Two goose down duvets

Bought as presents for my adult kids.

Hotel luxury at Home

I bought this duvet in the grey which I've never seen offered elsewhere. The quilting makes it look thick and poofy yet it's incredibly light and airy. I bought the largest size down pillows to match which could be softer so I'll use them as shams. I did have an issue with the duvet cover set I ordered but Customer Service worked with me to find a solution that worked for both of us. I appreciated that! I would definitely buy again in the future and recommend this Company... I will attach pics at a later date.
