This cotton sateen sheet set re-imagines your sleeping space with its crisp, smooth texture and breathable fabric. Made from 100% cotton, it includes a fitted sheet, a flat sheet, and pillowcases (one for the twin size, two for others). Each piece uses a 400-thread count with a sateen weave, giving it a tightly woven, silky-soft feel. Plus, the 16" pocket depth ensures a snug fit on most mattresses. We recommend running this set through a wash cycle before your first use for ultimate freshness and softness.
