Entrepreneur Binith Shah is on a mission to create the ultimate sleep experience. How? By using the rarest Eider duck feathers, gathered painstakingly and sustainably in a sanctuary in Iceland, and then having craftspeople integrate them into the best duvets in the world in Chablis, central France. Shah talks LUX through what inspires him, and takes us on a photographic voyage through the process of his craft
“One unforgettable night, I experienced the most restorative sleep imaginable, enveloped in a duvet that seemed to float above me. It was airy, plush, and perfectly temperate, as though I were cocooned in tranquility. From that moment, I was driven to share such an experience with the world.
The search led me to a rare and precious natural resource, one deeply tied to sustainability, conservation, and respect for the artisan’s hand. I partnered with a third-generation, ethical Eider duck sanctuary owner in Iceland and a B-Corp certified atelier in France that share our reverence for precision and detail. When I learned that the Japanese word for down is umō, I felt an immediate kinship with their design philosophy—pure, elevated, and intentional. From this harmony, UMŌ Paris was born.
Each duvet is a quiet masterpiece, marked only by a tonal feather embroidery – an unspoken tribute to the craftsmanship within. My hope is simple: that your sleep is transformed, as mine has been, by the unparalleled beauty of UMŌ.”
The undulating wetlands within the sanctuary provide ducks and their nests’ shelter from the frigid winds off the sea– as well as protect them against predators. The sanctuary caretakers create flagged gridlines and yellow mesh balls as visual cues to easily navigate the nests.

Tiny, vulnerable ducklings leave the nest soon after they hatch. They are typically led to the water by their mother, often with other females joining to form a “crèche” to protect them.
UMŌ’s third-generation caretaker and partner begins to sort through the valuable raw Eiderdown gathered from the nests and sanctuary grounds.

It takes 65 hours to hand clean every 2.2 kilos of Eider down, and nearly 9,000 hours from nest to final duvet. This skilled, heritage craft, coupled with Eiderdown’s scarcity as dictated by nature, creates the ultimate in natural rarity value.

Rare Eiderdown is carefully stored in a secure, climate-controlled safe to preserve its exceptional qualities and provenance.
Covers are expertly sewn by hand using a cotton sateen, created exclusively for use with Pure Arctic Eiderdown, ensuring complete traceability.
Each duvet is measured by hand.
All duvet covers are hand-cut in the workshops.
Spools of thread await the bourdon stitch — a decorative, dense seam that has become a distinctive signature of the atelier’s craftsmanship.

Following the quilting, each duvet undergoes a final quality control process.
The atelier uses time-honoured wicker tools to distribute filling evenly — a slow, manual technique that preserves the loft and comfort of the duvet.
As another nod to the art of the detail, fine embroidery bearing the UMŌ Paris wing logo is applied, symbolising the alliance between heritage craftsmanship and contemporary design.
Each piece is finalised with the UMŌ Paris label — the bespoke touch of La Compagnie Dumas artisans.
As this woman deep in REM sleep will attest when she awakes, there is nothing like the sleep you get when enveloped in UMŌ, the best duvet in the world.
