What is a bed called when the top sheets are fanfolded to the bottom?

When the top sheets are fanfolded to the bottom of the bed, this arrangement is referred to as an open bed. This method is used primarily in healthcare settings to facilitate easy access for patients who are being admitted or are undergoing examination or care. An open bed signifies that the bed is prepared for a patient, indicating that the linens are settled in a manner that allows for the immediate use of the bed.

In contrast, a closed bed would indicate that the bed is made up entirely and is not currently in use, typically with the top sheets tucked in. An operating bed would refer to a specialized table used during surgical procedures, while a medical bed generally denotes a bed designed for hospitalized patients, but does not specify the state of the sheets. Thus, the term "open bed" accurately describes the condition where sheets are positioned for easy patient access.
