Crafted in Italy; woven from 100% long-staple cotton, dyed, and tailored by our expert textile artisan partners. Silky and soft, sateen is a favorite for its smoothness, warmth, and subtle sheen. Fitted sheet features elastic on all sides and fits mattresses up to 18 deep, flat sheet features a 1 ¾ hem, and pillowcases feature a side envelope closure for a cleaner, more elevated look. Sheet set includes one flat sheet, one fitted sheet, and two pillowcases. King Sheet Set includes king-sized pillowcases; Queen Sheet Set includes standard-sized pillowcases. We recommend pairing with our Pillow Insert, available in King (PILKING) and Standard (PILSTAND) sizes. As you live in and launder our Italian garment-washed bedding pieces, the fabric will relax to become even more soft over time. Designed to layer beautifully with coordinating pieces, The Bedding Collection by Arhaus has been curated to instill your everyday moments with comfort and to evoke your most restorative rest.
