FAQs
What fabric is used in this duvet set?
This set is made from 100% long-staple organic cotton with a 400-thread-count sateen weave, giving it a soft, smooth, and lightly lustrous feel that becomes more comfortable with each wash.
What’s included in the set?
Each set includes a duvet cover and matching pillow sham(s) — one sham for Twin, and two for Queen and King sizes. The pillow shams feature a secure envelope closure.
Are these duvet covers hypoallergenic?
Yes — because they’re made from GOTS-certified organic cotton, they are naturally gentle and suitable for many sensitive sleepers and chemical-conscious homes.
How does the internal tie system work?
The duvet cover includes 8 internal ties that help anchor your insert in place and prevent shifting or bunching for a smoother sleep surface.
Is this duvet set eco-friendly?
Absolutely — the cotton is GOTS-certified, meaning it’s grown and processed without harmful chemicals, and the set is shipped in a reusable organic cotton bag to reduce plastic waste.
How should I care for these sheets?
Machine wash in cold water with mild detergent and tumble dry on low. Avoid bleach or harsh chemicals to preserve softness and prolong the life of your duvet set.
What’s the difference between a sateen duvet and a percale duvet?
Sateen has a silky, smooth texture with a slight sheen, making it soft and cozy, whereas percale offers a crisp, matte feel — both from long-staple organic cotton but different tactile experiences.
Will this work year-round?
Yes — natural cotton sateen is breathable and comfortable in both warmer and cooler seasons, providing balanced comfort without overheating
