The Graham Field-3857 and 3858 series are high-quality protective covers sold under the Grafco brand. These cases are constructed from heavy-duty vinyl to provide a total fluid barrier for pillows in hospitals or long-term care facilities. The 3857 model features a secure zipper closure to completely encase the pillow, while the 3858 uses a convenient overlap closure for quick changes. Both models are designed to be durable and easily wiped clean with standard disinfectants.
