Hospital bed sheets are linens designed for comfort, hygiene, and to fit standard hospital beds, often featuring a fitted design with elastic for a snug, secure fit. Their primary uses include providing a clean, comfortable sleeping surface for patients, managing infection by acting as a barrier, and facilitating ease of bed-making for caregivers. They are typically made from durable materials like cotton and polyester blends or disposable materials, and are washable for reuse or designed for single-use in medical settings.
