Description
Description
Sasa (笹) means bamboo leaf. Light, green and always moving with the breeze. This fabric behaves the same way.
The cover you sleep under, woven from 100% bamboo viscose: silky to the touch, naturally breathable and moisture-wicking, so you sleep cool on warm nights and comfortable on cold ones. The smooth fiber gives dust mites and bacteria little to hold on to, making it a gentle choice for sensitive and allergy-prone skin.
Sold as a single duvet cover, available in multiple sizes. Pairs with the Sasa Flat Sheet and Pillowcase Set.
Nothing between you and rest.

The problem
Most bedding is plastic.
Over 60% of bedding sold today is polyester — spun oil, dressed as comfort.
It sleeps hot
Polyester traps heat and moisture against your skin. That 3am kick-the-duvet wake-up? That's plastic.
It sheds microplastics
Every wash releases microfibres into water, soil — and eventually, you.
It ages badly
Pilling, static, that clammy sheen. Synthetic fibre wears out; natural fibre wears in.
Compared
Not all bedding is equal.
Year-round
One bed, every season.
Summer nights
Cool-touch lyocell wicks moisture twice as fast as cotton — dry, weightless sleep through the warmest months.
Winter mornings
The same fibre tempers warm air close to the body — warmth without the weight, no static, no clamminess.
The feeling
The five-star bed, at home.
Crisp, cool, impossibly smooth — the turn-down feeling, every night.
The Yuki difference
Made slowly, on purpose.
Closed-loop lyocell
Botanic fibre spun in a loop that recycles 99% of its water and solvent. Nothing petroleum-born, ever.
Grown, not synthesised
Flax from rain-fed fields in Normandy. Long-staple cotton, combed for a crisp, durable hand.
Finished by hand
Hidden closures, corner ties, stonewashed with water and time. No resins, no brighteners.
Delivered clean
Paper box, cloth bag, carbon-neutral freight. Zero plastic, anywhere.
Real bedrooms
Slept on, loved.

Questions
Asked, answered.
Bedding sets come in M and L; duvet covers run from 180×200 cm to 220×240 cm. The size guide beside the size selector lists the exact duvet and pillow dimensions for every option.
Lyocell is cool-touch, fluid and moisture-wicking — the coolest sleep of the three. Cotton percale is crisp and hotel-like. Silk is the gentlest on skin and hair. Everything is OEKO-TEX® certified and ships plastic-free.
No. Every piece is pre-shrunk in finishing, so the size you order is the size that stays. Wash cool on a gentle cycle and skip the softener — the fibre softens by itself, wash after wash.
