In addition to a flat sheet and fitted medical bed sheets, a hospital sheet set may also include a hospital-grade cover to protect the mattress from spills, stains, and other contaminants.  Hospital Sheet Set coverings are typically waterproof and can be easily wiped clean or machine washed, providing an extra layer of protection and hygiene for patients.

Blanket Cover
A blanket cover is a very lightweight decorative covering that is layered over a blanket, almost like a decorative top sheet. A blanket cover is often used on hotel beds as the outermost layer over a blanket, protecting the blanket so it won’t need frequent laundering. The fitted sheet, flat sheet, and blanket cover can be pulled off the bed and washed in a single load. Blanket covers are usually poly/cotton blends, requiring very little attentions; no ironing necessary.
