What is flat sheet vs fitted sheet

A flat sheet and a fitted sheet are two different types of bed sheets with distinct purposes:

Flat Sheet: A flat sheet, also known as a top sheet or bed sheet, is a rectangular piece of fabric that is placed on top of the fitted sheet but beneath any blankets or duvets. It is typically larger than the fitted sheet and is used to cover the sleeper. The flat sheet acts as a barrier between the sleeper and the blankets, providing an additional layer of comfort and protection. It is usually tucked in at the foot of the bed and can be folded back over the blankets for a neat appearance.

Fitted Sheet: A fitted sheet, sometimes called a bottom sheet, is designed to fit securely over the mattress. It has elasticized corners that help it stay in place and prevent it from slipping off during sleep. Fitted sheets are tailored to specific mattress sizes (e.g., twin, queen, king) and have deep pockets to accommodate different mattress depths. The primary purpose of a fitted sheet is to protect the mattress and provide a smooth, snug surface for the sleeper to lie on.

In a bedding set, you often receive both a fitted sheet and a flat sheet. However, some people choose to forego the flat sheet and use only the fitted sheet along with a blanket or duvet. The preference for using or omitting the flat sheet varies among individuals and cultures.
