Fitted sheets have an elastic to wrap around the mattress and prevent it from moving too much while you sleep. While these sheets protect your mattress from body oils, spills, and other things, using a mattress protector underneath your fitted sheet is a good idea for extra protection. Flat sheets lay on top of fitted sheets to protect your duvet or comforter from body oils and tearing. Not everyone uses these, but we recommend doing so.

Flat Sheet
The flat sheet is the first covering over the fitted sheet. It's the layer that touches the body, providing a hygienic, easy to wash barrier between you and other bed coverings used for warmth and/or decoration. Luxury sheets can hang down the side of the mattress though traditionally they are tucked in all the way around for a more polished presentation.
