In addition to their functional role, bed linens come in various colors and patterns, allowing for personal expression in bedroom decor. Regular washing and maintenance are important to keep them clean and fresh. Properly fitted sheets and quality linens can enhance the overall sleeping experience, contributing to better rest and relaxation.
