Bed made in 10 seconds
Never put on a cover again.
Corners that never land in the right place, the duvet balled up at the bottom of the cover, ten minutes wasted on a bed that always looks unmade: those days are over.
Cumulus combines the duvet and the cover in a single piece. Spread it out, and the bed is made. No accessories, no wrestling, a neat bed in one move.

Hygiene
It washes like a simple sheet.
With a classic duvet, you wash the cover… and the duvet keeps sweat, dust and dust mites for years. Cumulus goes whole into a standard machine, in a single cycle.
All seasons
Always the right temperature.
Its breathable filling releases excess heat and keeps the warmth you need. No sweating, no shivering, no stuffy feeling.
Cool in summer
The fabric breathes and lets heat escape: no more waking up drenched in sweat.
Warm in winter
The hollow fibres trap air and keep in body heat all night.
Light all year round
Fluffy as a cloud, never weighing you down.

Frequently asked questions
Everything to know before you order.
What exactly is a 2-in-1 duvet?
It's a duvet with the cover already built in: the outer fabric is sewn around the filling. You only have one piece to put on the bed and no more cover to put on.
Will it fit in my washing machine?
Yes. Every size, even the 230 × 230, fits in a standard 7 kg machine.
How do I wash and dry it?
Machine wash at 40 °C on a delicate cycle. Air dries in about 2 hours, or tumble dry on low heat with two dryer balls to restore all its loft.
Is it warm enough for winter?
Yes. The hollow-fibre filling keeps in body heat while letting you breathe: it's suitable all year round in a normally heated bedroom.
Can I still use a cover?
Yes, if you want to change the look. But it's no longer necessary: Cumulus is made to be used as is.
How does the 100-night trial work?
Sleep with your duvet for up to 100 nights. If it isn't right for you, write to us: we'll arrange the return and refund you.

I spread it out in the morning and the room looks tidy, even when it isn't. After a wash, it kept its shape and color. I would buy the 230 × 230 size again for the big bed.

Bought for my 15-year-old daughter, in purple just as she wanted. She says it’s “like sleeping on a cloud.” I appreciate that she makes her bed all by herself in ten seconds.

I chose cream beige for the children's room. Very soft, light, and what convinced me: I washed it after a week and it was dry on the balcony in two hours. Excellent value for money.

My mother used to have trouble putting on the duvet cover. With this one, that problem no longer exists. The red warms up their bedroom in their old house. They wanted a second one for guests.

It weighs half as much as my old duvet, but I’m not cold at night. The diamond stitching keeps the filling in place so it doesn't all end up on one side. Delivery in five days.

I am allergic to dust mites and I wash my bedding every two weeks at 40°C. For the first time in years, I wake up without a stuffy nose. The included pillowcases are of the same quality.

I was skeptical about the quick drying. Washed Saturday morning, back on the bed after lunch. The mint green goes very well with the wood in the bedroom. The fabric is quiet; it doesn't rustle.

As a student living away from home with a shared washing machine, I never used to wash my old duvet. This one fits into a 7 kg machine with no problem. The blue is identical to the photos.
