Product information
You haven’t experienced a duvet like this before
The Megafluff duvet from Happy Fluffy Cloud is a large, fluffy, warm and heavy premium down duvet that elevates your sleep comfort.
It contains more down and feather filling than other duvets and has no traditional baffle stitching, allowing the generous down filling to move freely inside the duvet. This means the duvet may need to be “fluffed” at bedtime to evenly distribute the down - a feature some love and others may need time to get used to.
Those who enjoy sleeping warm and well tucked in will experience dreamlike sleep under this cloud-like duvet.
• Premium down blend. Approx. 50% down & 50% feathers.
• Made in Tuscany, in a family-owned factory.
• Please Note! Happy Fluffy Cloud products are only sold on this official website. Stay safe and make sure you’re shopping the real fluffy goods. If you ever feel unsure, we’re always here to help.

FAQ
Why should I choose a Happy Fluffy Cloud duvet?
Do you enjoy a cozy sleep with warmth, fluff, and weight? Then this is your new sleeping buddy! The duvet is cozier, larger and fluffier than any other duvet on the market. You've never experienced a duvet like this before, and that alone is thrilling.
What IS a fluffy duvet?
Sleep cloud, down duvet... this type of duvet has many names and surely even more descriptions. Happy Fluffy Cloud is our vision of a classic down duvet with the best natural properties for a good night's sleep. The duvet lacks channel stitching. It's essentially a "bag" with just the perfect amount of filling for comfortable weight and cozy warmth. Our Megafluff single duvet weighs a whopping 4.8 kilos(!) and it's part of the experience and the cool thing - that a fluffy duvet can feel both airy and heavy at the same time.
What are the advantages of a fluffy duvet?
A high and fluffy duvet creates a cozy, snug nest. Under a heavier duvet, we fall asleep more easily and sleep deeper as the body settles and stays still. Its ability to provide warmth and regulate temperature is also an incredible advantage. That's why the vast majority absolutely LOVE their sleep clouds.What does the lack of channel seams mean?
Our down duvets lack channel stitching. This may feel unusual, but it's also why this duvet is perceived as more luxurious than others. The absence of channel stitching means that the down lies freely within the duvet and moves at its own will. This means that you can shake the down towards the foot of the bed if you have cold feet or gather the down over your chest if you desire weight and warmth on top.
Learn to handle a duvet without channel stitching!
Down and feathers usually take a few days to fully expand after being slightly compressed in packaging during transport. So it may take a few nights to discover the duvet’s full potential. It can also take a bit of practice to achieve optimal sleep under this cloud-like cover - the down needs a little help to spread the way you prefer:- Start by placing the four corners of the duvet in the desired position on your bed. Do not shake.
- Sweep your arm across and then press on the duvet to push the down around and distribute it evenly.
Generally, you’ll need a few extra seconds to make the bed after your heavenly night’s sleep - it’s mostly just unfamiliar at first and might seem a bit fiddly. But once you fall in love with the duvet, you won’t care that it takes over your bed and doesn’t lie flat like your previous (...boring?) one.
What is the difference between a duvet and a comforter?
Duvets are more commonly used in Europe and is a soft bag filled with down and feathers, designed to be inserted into a duvet cover which can be washed, and are known for their warmth and insulation. While comforters are standalone blankets with built-in quilting and are more popular in the United States. Unlike a duvet, a comforter is typically sewn or quilted to keep the filling evenly distributed.
How do I care for the duvet?
Machine wash
Wash only in exceptional cases and then with down detergent. Our duvets can be washed at 30 degrees Celsius, making them suitable even for allergy sufferers. After washing, it is important to dry the duvet thoroughly in a tumble dryer, preferably with tennis balls. This takes time, but it is crucial that the duvet is completely dry, otherwise the down can clump, and the duvet may lose its fluffiness.Dry cleaning
Dry cleaning is also an option for our duvets.Shake & air
By shaking and airing your duvet regularly (preferably in sub-zero temperatures), it stays fresh for a long time. When the duvet is shaken and aired, the down and feathers straighten out, regain their resilience, and regain the natural properties that make the duvet incredibly fluffy.How do you store a down duvet/down pillow?
Store duvet and pillows in a dry place, preferably in the dust bag provided with the duvet. Air (or wash if necessary) duvet and pillows before storing them away for the season. Make sure they are completely dry, fold them up and reunite when autumn arrives. Vacuum-packing duvets or pillows is not allowed, as the feathers may risk being damaged.What if I don't like the duvet?
Since duvets are hygiene products, you cannot return a duvet you unpacked from the bag/used and slept with. Only unused quilts in original packaging (bag) are accepted as returns. We are therefore happy to help guide you in the right direction in our fluffy world!
Experiencing that a blanket is too warm, too heavy or too big is usually a matter of habit! We both believe and hope that you will fall in love with (...and even fall in love with) your down duvet. It is most likely that you need a short break-in period. Down and feathers usually only expand fully after a few days, after being slightly compressed in packaging before transport. It may therefore take a few nights to get to know the quilt's full potential. It may also take some practice to get the optimal sleep under this sleeping cloud - the down needs a little help on the trot to be distributed as you prefer.More questions & answers
