Fitted Sheets vs. Flat Sheets: Understanding the Difference
Understanding the difference between a flat sheet and a fitted sheet will help you know which layers to choose to make your most comfortable bed. Both bedding pieces are included in a sheet set, but can often be purchased separately as well. With this in mind, how do you choose which to purchase? Learn the qualities and advantages of fitted versus flat sheets, including which is optional and which is essential, and why you might want to use both.
Difference Between Fitted and Flat Sheets
The difference between flat and fitted sheets is implicit in their respective names: A fitted sheet features elastic on all four corners so it slips on snug—or ‘fits’—around the mattress. In contrast, a flat—or top—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 fitted sheet, but each piece is made to serve a specific purpose on the bed. And while both types of sheets provide a protective layer against the dirt, bacteria, and perspiration your body sheds during the night, only a fitted sheet is essential.
Do You Need a Flat Sheet?
Since bed sheets are sold separately as well as in sets, you may be wondering whether you actually need a flat sheet. Technically, the answer is no: A flat sheet is optional. You can layer a perfectly comfortable bed without a top sheet, especially if you use a duvet cover that’s easy to put on and pull off—and therefore easy to wash on a regular basis. But there are several reasons you may prefer to add a flat sheet to your bedding design:
- Hygiene: Even if you use a duvet cover, you may still want to add a hygienic barrier between your body and the duvet. A linen, percale, or bamboo flat sheet is lightweight and breathable enough that it won’t add much extra warmth, but can safeguard your bulkier bedding from dirt, dust, and perspiration.
- Comfort: If you tend to sleep hot or live in a warmer climate, a top sheet makes it easy to adjust your comfort with minimal effort overnight. Simply toss off your top bedding layer when the temperatures rise too much for restful sleep.
- Convenience: Flat sheets simplify your laundry routine; they require less water, energy, and space to launder than a comforter or duvet cover. And if you use a flat sheet, you can wash your other layers less frequently.
- Preference: You don’t necessarily need a reason to use a flat sheet. If it’s what you’ve always done, or how you feel most comfortable, choose a top sheet to make your bed the best for you.
If you prefer a matching look or the comfort and convenience of a flat sheet, consider buying sheets by the set. If not, sheet separates may be the better option so you have precisely the pieces you need.
