Flat Bed Sheets in 100% Cotton

Flat Bed Sheets — More Than Just a Layer, the Heart of a Well-Made Bed

A well-made flat sheet does two things — it looks right on the bed and feels right against skin. Our flat bed sheets are made from 100% natural cotton fibers with no synthetic blends and no plastic fibers, woven for softness, breathability, and the durability to hold up through frequent washing without losing their shape or hand feel. Generously sized to tuck cleanly or drape loosely depending on how you make the bed, these flat cotton bed sheets are available in every size from twin to california king — including twin flat sheets and queen flat sheets for the most common bedroom setups.
