Which linen is used to provide warmth and serve as a barrier to other bed covers?

The top sheet is designed to provide warmth while also serving as a barrier between the blanket or comforter and the individual. It creates a comfortable layer that keeps the person cozy without being directly in contact with heavier bed covers, which can promote better hygiene and comfort. The top sheet allows for airflow, making it easier to regulate body temperature and enhancing the sleeping experience.

In contrast, a rubber sheet is primarily used to protect the mattress from moisture, a bottom sheet lays directly on the mattress and serves as the foundational layer, while a draw sheet is typically used for moving patients or protecting the bed from spills, rather than providing warmth. Hence, the role of the top sheet is distinctly focused on warmth and comfort as well as maintaining cleanliness against the heavier layers of bedding.
