Sustainable and silky soft. And we can prove it.
Too warm, and you don't know why
Sound familiar?
You read the label on everything you buy. Except what you sleep in.
You read labels, compare materials and choose consciously. But bedding labels rarely make you much wiser, even though the fabric lies against your skin night after night. That can be more concrete.
Waking up drenched in sweat, while the room feels cool
Sheets that hold moisture and feel clammy
"Eco" and "natural" on the label, with no explanation of what that means
Doubt whether sustainable can really be just as soft
The facts
Less overheating, substantiated step by step.
No mood story. This is what our fabrics do while you sleep, and why you can rely on it.
Moisture is carried away, not held
Our fabrics absorb sweat and draw it away from your skin, instead of holding onto it like conventional cotton. Tencel™ Lyocell even absorbs up to 50% more moisture than cotton. You stay dry, even when things heat up.
Your temperature stays steady
The fabrics breathe with your body heat and keep a cooler microclimate around your body. Your body doesn't have to work overtime to cool itself, and you'll notice that in how deeply you sleep through.
Backed by certifications
Our organic cotton is GOTS-certified (CU-1003204). Tencel™ Lyocell is OEKO-TEX and FSC certified and made in a closed loop that reuses over 99% of the water and solvent. Silky Smooth is made with GRS-certified recycled materials. Independently verified, so you can look it up.
“With the children dealing with eczema I was nervous, but it's extremely soft, it breathes, and that's what makes it so lovely.”
Proven, not presumed
Every claim is on paper
Cool and dry, measurably
Moisture-regulating and breathable: not a marketing term but a property of the fibres themselves. Tencel™ Lyocell absorbs up to 50% more moisture than cotton and keeps a cooler microclimate around your body.
Safe for your skin
Our fabrics are soft, hypoallergenic and create less friction than conventional cotton. Free from irritating additives and suited to sensitive or easily irritated skin.
Responsibly made, traceable
Organic Cotton is GOTS-certified (CU-1003204), Tencel™ is made from FSC-certified eucalyptus in a closed loop (over 99% reuse), and Silky Smooth uses GRS-certified recycled materials. Certificates you can look up, not container terms.
Choose on facts, not guesswork.
Not every skin and sleep pattern asks for the same thing. That's why we explain per line what the fabric does and what the certification stands for, so you can choose based on facts.

Frequently asked questions
No, and that's not an opinion but a property of the fibre. Organic cotton and Tencel™ Lyocell are naturally smooth and supple, without chemical softeners. The 4.9/5 from more than 1,000 sleepers is first and foremost about exactly that feeling.
Organic Cotton is GOTS-certified (CU-1003204). Tencel™ Sateen is OEKO-TEX certified, comes from FSC-certified eucalyptus and is produced in a closed loop that reuses over 99% of the water and solvent. Silky Smooth is made with recycled materials: we work with partners whose materials are certified to the Global Recycled Standard (GRS), and the fabric itself is OEKO-TEX certified. What we can't show, we don't claim.
GOTS stands for Global Organic Textile Standard, the strictest international standard for organic textiles. The certification covers the entire chain, from fibre to processing, and is audited by an independent certifier. So it's not our own label, but external verification.
Choose Tencel™ Sateen for the coolest, lightest and most breathable feel. Choose Silky Smooth for a warmer, cuddly-soft and crease-free bed, or Organic Cotton for a natural, fresh feel in every season. Still not sure? Take our bedding quiz and find out in one minute.
