What is a Duvet Cover? Your Complete Guide


Are you thinking about buying a brand-new duvet cover or set? If you're wondering, "What is a duvet cover?" and aren't sure why you need one or what you use it for, we urge you to keep reading! In addition, if you don't know where or how to begin the blanket selection process, we've got you covered! 

What is a Duvet?

Duvets are soft, fluffy inserts placed on top of mattresses to provide warmth throughout the night (usually without needing additional bedding or blankets). Duvets consist of two pieces, the insert and the cover (similar to how a pillow goes into a pillowcase). For duvet inserts, a variety of filling options are available. These include feathers, down, synthetic fibers (polyesters), wool, cotton, and microfibers.

When you know the filling you want, you can choose how heavy you want the blanket to be. Naturally, the heavier the blanket, the warmer it will be. Generally, duvet inserts are white and come without any patterns or embellishments. This means can choose the colors and styles you prefer for your cover and change them whenever you feel inspired. 

Types of Duvet Inserts

The fill, or the material, inside a duvet's insert, determines the loft or fluffiness of the duvet. In general, inserts are made of natural down or synthetic fibers. For example, goose and duck feathers are used to make natural down, from smaller feathers underneath the larger quilled feathers. Down is lightweight, fluffy, and provides warmth and insulation during cold months, making it a suitable choice for cold sleepers throughout the year. Some people may, however, experience allergic reactions to down.

Leesa inserts are made from 100% polyester, ensuring they are machine washable, lightweight, hypoallergenic, ethically sourced, and animal-free. In addition, Leesa's insert has a soft, comfortable, and breathable 100% organic cotton shell, the fabric between the insert and the cover. Further, Leesa's shells are equipped with four internal ties to ensure the insert stays in place all year without needing to be re-fluffed.

What is a Duvet Cover?

In the same way, a pillow resides inside a pillowcase; a duvet cover encases a duvet insert. Typically, you will see a side with buttons, snaps, ties, or zippers; these are the sides you will open to place your duvet in and close afterward.

These covers provide an extra layer of protection for your comforter against body oils and stains and are machine washable. Of course, not everyone will want to use a duvet cover, which is entirely okay. However, we strongly recommend one because it is thinner and lighter, making it significantly easier to wash than your duvet! Read the manufacturer's cleaning instructions before washing your duvet cover for the most successful results.

Types of Duvet Covers

Duvet covers are available in various fabrics and can be tailored to match your sleeping style, the season, and environmental considerations. Duvet covers come in flannel, cotton, linen, polyester, bamboo, or silk.

How to Choose a Duvet Cover

Consider the material

  • Cold sleepers should choose a material that keeps them warm

  • Hot sleepers should pick breathable and absorbent materials 

Choose the right size duvet for your bed

  • Choose the right size duvet for your cover; extra space shouldn't exceed a few inches

Thread count

  • In contrast to sheets, you want a lower number, somewhere between 140 and 300; anything higher will result in a heavy cover

Cleaning and maintenance

  • Are you looking for dry-clean only, or do you want it to be able to be washed at home?


  • Identify your budget and the type of cover you need based on your needs and your budget

How Often Should You Wash a Duvet Cover?

Clean bedding is essential to a good night's rest and your health! Duvet covers should be washed the same way as other bedding. The best approach is to gauge how much use it receives based on how often it is used. 

Some questions to consider are: 

  • Do you use a top sheet or sleep directly on or under the duvet cover?

  • Are kids or pets resting or crawling on the top? At night, do you sweat and overheat? 

  • Are you sharing a bed with anyone? 

    • Two people's sweat and skin cells are twice those produced by one, so wash accordingly!

  • Does your bedroom have a humidifier?

    • Sheets can become damp and prone to bacteria if they get exposed to moisture

  • During the night, do you keep a fan running?

    • You may be blowing dust mites all over your bed

Answering "yes" to most questions indicates that you should wash your duvet set, pillow shams, and sheet weekly. Weekly cleaning might sound like a lot, but trust us, it's well worth keeping skin and body oils, sweat, saliva (for droolers), and dander at bay.

How to Put on a Duvet Cover

Duvet covers are great blankets! However, the first and most important step is getting the duvet cover over the duvet insert. We've made a step-by-step guide on how to do this process so you won't feel frustrated before sleeping with your new duvet set! 

  1. Turn the duvet cover inside out

  2. When you lay your duvet cover on your bed, the opening should be at the foot

  3. Place your comforter over the cover

  4. Tightly roll the duvet cover from the head of the bed toward the foot

  5. Cover the bundle's sides by inverting the cover's opening. Close the duvet cover with a button or zipper 

  6. Once you have completed unrolling the bundle (this time from the feet to the head), fluff it up! 

Duvet vs Comforter: What's the Difference?

It is common for people to confuse the words duvet and comforter, but the two are different. Typically, comforters contain polyester, down (Goose or duck feathers), cotton, or wool stuffing stitched around the perimeter to prevent shifting. Various colors and patterns are available, as well as different thicknesses to suit different climates and sleeping preferences. 

Inside the duvet cover is a duvet insert. If you just asked yourself, "what is a duvet cover?" you are not alone! A duvet cover is essentially the "case" that protects the duvet insert. The inserts are similar to comforters in that they are stuffed and sewn together. Most duvet inserts are made of natural down or synthetic materials that mimic natural down. In addition, the outer layer is made of cotton and stitched together to keep the stuffing from falling out. Duvets also come in various weights to fit cool and warm temperatures. While the inner layer of a duvet often only comes in white or off-white, covers are available in a wide assortment of colors and patterns and protect the inner layer from stains and spills. Since duvet covers are often inexpensive, you can upgrade them whenever you want to upgrade your bed's appearance. Unlike a comforter, a duvet has a cover. In summer, duvet covers function as top sheets, and duvets can be used without a cover, whereas the comforter will remain the same.

What features to look for in a duvet cover?

You should first consider what material suits your needs (i.e., whether you sleep warm or cold, what is comfortable for you, or if you have any allergies). After that, make sure you know the size of your mattress (to ensure the cover fits snugly over the insert). Next, decide how heavy you want the cover to be (the lower the thread count, the lighter the cover). The next step is determining how much cleaning and maintenance you are willing to perform; different fabrics require different upkeep. Be realistic about this! Don't worry; we won't judge you! Lastly, decide what price is acceptable to you.

Can I put a regular comforter in a duvet cover?

It certainly is possible, but that does not mean that you should! Because comforters are machine-washable, they are ready to use immediately after purchase.
