Traceable from Field to Fabric
When it comes to organic cotton, certifications matter. That’s why all our cotton products carry respected labels like GOTS (Global Organic Textile Standard) and OEKO-TEX®. These ensure our bedding is made without harmful chemicals, produced under strict environmental standards, and safe for both you and the planet. Many of our customers choose organic because it feels healthier, reduces exposure to toxins, and helps protect ecosystems from soil to sea.
We believe your bedding’s story should be as pure as the cotton itself. That’s why we work with partners using C-Track technology an advanced system that securely tracks the journey of our organic cotton, from certified farms to your hands. Each stage is logged, verified, and transparent, ensuring the cotton in your bedding is exactly what we claim: responsibly grown, ethically made, and honestly traced.
Why It Matters
True sustainability starts with truth. With C-Track, you can rest easy knowing our cotton is never blended or mislabelled, just genuinely organic, every step of the way. It protects farming communities, preserves ecosystems, and gives you peace of mind in knowing your bedding is part of something better.

300 Thread Count Organic Cotton Sateen Duvet Cover
Wrap yourself in relaxed, sustainable luxury with our 300 thread count Organic Cotton Sateen Duvet Cover, thoughtfully designed for a smooth, softly indulgent sleep.
Woven from long-staple, GOTS-certified organic cotton, the sateen weave creates a fabric that feels silky and fluid against the skin, with a subtle sheen that adds quiet elegance to the bedroom. Naturally breathable with gentle warmth, it offers year-round comfort without heaviness.
Designed to be as practical as it is refined, the duvet cover features hidden button closures and internal corner ties to keep your duvet neatly in place, while the knife-edge hem delivers a clean, tailored finish. The fabric softens beautifully with every wash, making it effortless to care for and a pleasure to sleep in over time.
Complete the look with the matching fitted sheet and pillowcases, available separately for a perfectly coordinated and elevated sleep space.
