Flat Sheets vs. Fitted Sheets: Understanding the Difference
Flat sheets create a barrier between the sleeper and their top layers of bedding, while fitted sheets protect the mattress and create a smooth sleeping surface. You don’t need to have a fitted and a flat sheet, but whether you choose one, the other, or both is up to personal preference. Understanding the differences between a flat sheet and a fitted sheet will help you know which layers to choose to make your most comfortable bed.
In this guide, we break down the qualities and purposes of fitted versus flat sheets, including which is optional, which is essential, and why you might want to use both.
Difference Between Flat and Fitted Sheets
Flat and fitted sheets serve different purposes in your bedding setup. A flat sheet lies between you and your top bedding layer, such as a comforter or quilt. A fitted sheet goes directly over the mattress to create a smooth, secure base. Both offer a layer of protection against dirt, sweat, and bacteria, but only the fitted (or bottom) sheet is essential.
Flat and fitted bedding pieces are included in a sheet set, but can often be purchased separately as well.
Here’s a quick comparison:
- Fitted Sheets: A fitted sheet features elastic on all four corners so it slips on snugly—or ‘fits’—around the mattress.
- Flat Sheets: A flat sheet does not have elastic corners, but instead lies flat and serves as a hygienic barrier between your body and any other bedding you may use. In a pinch, you can fold and then tuck a flat sheet to function as a bottom sheet.
