Organic Supima Fitted Sheet FAQs

What makes Supima cotton different from regular cotton?

Supima cotton represents less than 1% of the world's cotton and is prized for its extra-long staple fibers. These fibers create a smoother, stronger yarn that resists pilling and maintains softness over time — resulting in a fitted sheet that feels noticeably more refined than standard cotton and holds up wash after wash.

How deep is the pocket on this fitted sheet?

Our organic Supima cotton fitted sheet features a 16" deep pocket, designed to accommodate most standard and pillow-top mattresses. The elasticized perimeter keeps the sheet firmly anchored through the night, even if you tend to move around while you sleep.

Will this fitted sheet match my existing Naturepedic Supima set?

Yes. This fitted 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.

Is this Supima cotton certified organic?

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 fitted sheet is GOTS-certified organic, meaning the cotton was grown without synthetic pesticides or fertilizers and processed according to strict environmental and social standards.
