Drift into a peaceful slumber with the Cotton Flannel Deep Pocket Fleur De Lis Bed Sheet Set by Superior. Each set includes one flat sheet, one fitted sheet, and two pillowcases (one for twin size). The fitted sheet is fully elasticized and features a 15-inch deep pocket construction that stretches to fit oversized mattresses up to 18-inches thick. Crafted from 100-percent Cotton Flannel, the brushed flannel fabric is smooth to the touch and is designed to trap heat to insulate cold sleepers during the winter months, while keeping you cool and wicking away moisture during the warmer months. This sheet set is machine washable and is intended to get smoother and softer with every wash, making it a sleeping essential.
