Organic Supima Cotton Flat Sheet

That depends on how you sleep. A flat sheet adds a lightweight, breathable layer between you and your duvet or blanket, which many sleepers prefer for added comfort, temperature regulation, and flexible layering. It can also help reduce how often your heavier bedding needs to be washed. Others prefer a simpler, more minimal bed setup without a top sheet — it's ultimately a matter of personal preference.

This flat sheet is woven from Supima cotton — a fiber representing less than 1% of the world's cotton supply, prized for its extra-long staple fibers. Compared to our percale or standard sateen flat sheets, Supima offers a noticeably silkier hand feel, greater pill resistance, and heirloom-level durability. It's also the only flat sheet in our collection that features a decorative hemstitch for a refined, tailored finish.

Yes. This flat sheet is woven from the same GOTS-certified organic Supima cotton as our Supima Sheet Set and is available in the same colorways — Arctic Snow (WHT) and Natural Undyed (UND) — designed to coordinate seamlessly with your existing bedding.

Yes. Supima refers to the quality of the fiber — specifically extra-long staple cotton grown in the U.S. — but not how it's farmed. Our Supima flat sheet is GOTS-certified organic, meaning the cotton was grown without synthetic pesticides or fertilizers and processed according to strict environmental and social standards.
