Flat Sheet vs Fitted Sheet: What's the Difference?

Fitted Sheet

Lucas Lu |

In the hustle of our daily routines, we readily wash clothes and clean surfaces, yet the significance of our sheets often slips through the cracks. Given that we dedicate roughly a third of our lives to bed, the enduring discourse on sheets versus fitted sheets within the realm of bedding essentials becomes a focal point for those attuned to the nuances of comfort. The decision between these two types of sheets holds more weight than initially apparent. In the pursuit of the ultimate sleeping sanctuary, it's imperative to discern the distinctions between sheets and fitted sheets, unveil the mysteries of proper cleaning and maintenance, and delve into the functionalities they each bring to the realm of bedding.

What is a Flat Sheet Used For?

Flat sheets, as the name implies, rest smoothly on the bed's surface. Also recognized as a top sheet, this rectangular sheet is the layer that provides separation between you and your comforter or duvet. Unlike its counterpart, the fitted sheet, a flat sheet lacks elasticated edges.
While fitted sheets are often deemed a staple in bedding, the inclusion of flat sheets sparks some debate. Many older Americans view bedding as incomplete without flat sheets, whereas certain millennials see them as unnecessary.

Benefits of Flat Sheets

Maintain the cleanliness of your duvet to prevent stains. Regardless of whether you use a duvet, comforter, or quilt, sheets play a crucial role in keeping body oils away from your top bedding.


Regulate temperature efficiently. Opting for specialized cooling sheets can contribute to a cooler sleep experience during warmer weather. Conversely, you can invest in padded plush sheets to enhance the warmth of your bed during the winter.


Enhance sleep hygiene practices. Sheets are more manageable to wash than bulky bedding, significantly improving the cleanliness of your bed. This, in turn, enhances your overall sleep hygiene.

What is a Fitted Sheet Used For?

Also known as bottom sheets, fitted sheets feature elasticated corners of the sheet, sometimes on both sides. Whether you prefer silk or cotton, fitted sheets serve to protect your mattress, and their soft, flat surface provides extra comfort as you sleep.

Benefits of Fitted Sheets

Protect the mattress. The sheet is laid between the mattress or mattress protector. It keeps the mattress clean, which is important because you can't exactly throw the mattress in the washing machine. While most mattresses last 7-10 years, you can extend the life of your mattress with a sheet protector.

Provide a comfortable sleeping surface. A soft fitted sheet enhances your comfort. It also smoothes out any unevenness that may exist on the surface of the mattress or mattress topper, creating a flat sleeping surface.

Easy to clean. Like flat sheets, fitted sheets are easier to clean than the bedding they protect. Most sheets are machine washable and can also be dried in the dryer, so they are easier to clean than a mattress or mattress pad.

Key Differences Between Flat and Fitted Sheets

Shape and design

The shape and design of flat and fitted sheets are distinctly different. Flat sheets are basic, rectangular pieces of fabric, designed to lie on top of the bed. They usually drape over the sides of the mattress, providing a layer between you and your blanket or duvet. Fitted sheets, however, are designed with corners that have elastic sewn in, allowing them to wrap snugly around the mattress, providing a smooth sleeping surface without any loose fabric.


Elasticity is a key feature of fitted sheets. The elastic bands sewn into each corner ensure the sheet stays firmly in place on the mattress. This design prevents the sheet from slipping off or bunching up, making it ideal for restless sleepers. In contrast, flat sheets lack any form of elasticity. They are simply spread over the bed and require tucking under the mattress to stay in place.



Fitted sheets serve as a protective layer for the mattress, absorbing oils and sweat from the body. This helps in keeping the mattress clean and extends its lifespan. Flat sheets, on the other hand, are meant to act as a barrier between the sleeper and their blanket or duvet. They are easier to clean and replace, thus enhancing overall bed hygiene.

Use in Bed Making

Fitted sheets are the foundation layer, directly covering the mattress. Their snug fit provides a smooth base for the rest of the bedding. Flat sheets come next, lying atop the fitted sheet, usually tucked in at the sides and bottom for a neat finish. They serve as a comfortable, hygienic layer that directly touches the sleeper, completing the bed setup.


How Do You Know Which Sheet Is Best For You?

Choosing between flat and fitted sheets comes down to your preferences and needs. Consider these steps to decide:
Test a Flat Sheet: Use a flat sheet for a week. Notice if you mind the extra work of folding and tucking to cover your mattress.
Try a Fitted Sheet Alone: Sleep with just a fitted sheet, duvet cover, and pillow for a few days. See if this simpler setup affects your sleep quality.
Combine Both: Use both sheets together. If you often kick off the flat sheet, you might not need it. If you find it cozy, it's a good match for you.
Remember, fitted sheets can be tricky to fold and might end up wrinkled. If you prefer an easier bed-making process, sticking with a flat sheet might be better for you. Ultimately, the choice depends on what makes you most comfortable and your bed-making routine.


Changing and Caring for Your Sheets

Changing and caring for your sheets is essential for a clean and comfortable sleeping environment. Here's a simple guide to help you maintain your sheets effectively:
Regular Change: Swap your sheets every 1-2 weeks to keep things fresh and clean.
Follow Labels: Check care labels for washing instructions and use a gentle detergent.
Gentle Drying: Tumble dry on low or medium, and remove promptly to prevent wrinkles.
Stain Action: Treat stains ASAP with a suitable remover to keep your sheets spotless.
Smart Storage: Store sheets in a cool, dry place using breathable bags or a linen closet.
Bed-Making Basics: Fit the sheet snugly, smooth out wrinkles, and tuck for a neat bed appearance. Rotate and flip pillows regularly.
