Many sleepers enjoy the cozy feel of European-style duvet bed coverings, and a duvet insert is the internal component for these coverings. Normally filled with down, feathers, or down alternative fibers, this insert provides the duvet’s plush, lofty feel. A duvet insert is designed for use with a protective duvet cover, making the insert easy to keep clean. This characteristic distinguishes duvet inserts from comforters, which can serve as standalone bedding – though most comforters may also be paired with duvet covers.

Our team of experts has tested dozens of duvet inserts, as well as some comforters, to bring you the list of top picks below. The diverse testing team includes people with differing preferences when it comes to qualities like duvet insert loft, insulation, and breathability. This ensures our ratings reflect experiences for a wide range of sleepers. We also considered practical factors like pricing, ease of care, and how easily the insert can be secured to its cover.

Read on for detailed descriptions of our best duvet insert picks. The product profiles below include accolades for each insert that highlight areas where that product stands out from the competition. Further down, you’ll find our full duvet insert buyer’s guide. We’ll cover common materials and sizes for duvet inserts, how much you can expect to pay for different types of inserts, and cleaning and care recommendations.

The entire comforter can be washed and dried in household machines.

Eco-conscious shoppers searching for an all-season luxury option may find the Birch Duvet Insert worth considering. Birch is known for its commitment to ethical materials sourcing and manufacturing processes. While its price-point is a bit higher than average, shoppers who value quality materials and sustainable practices may find this duvet insert checks all their boxes.

The duvet insert’s fill is a blend of 70% Responsible Down Standard-certified down and 30% wool. This fill combination functions equally well in hot and cold climates. The down creates warmth while the wool ensures that the blanket wicks moisture and regulates temperature. The exterior is made from GOTS-certified organic cotton and is designed for maximum breathability.

Baffle box stitching keeps the fill in place and creates a lofty, airy feel. The insert is likely to have a long lifespan thanks to its double-stitched edges. Sleepers can attach the insert to a duvet cover using corner loops.

Shoppers may purchase the duvet insert in three sizes: twin, full/queen, and king/California king. This duvet insert can be machine washed. Birch recommends washing it on a cold cycle and using dryer balls while tumble drying low. The Birch Duvet Insert is backed by a 100-night sleep trial, a 2-year warranty, and it ships free to all 50 states.

Lab Notes – What Our Testers Thought

“The Birch feels cozy enough for cold temperatures, but there’s enough wool fill to balance out the down and prevent you from overheating.”

The Buffy Breeze is made from a plant-based, eucalyptus fiber that’s cool to the touch. Recommended for those who sleep hot or live in a warm climate, this duvet insert has excellent temperature regulation.

The Buffy Breeze contains 100% eucalyptus fiber fill encased in a 100% eucalyptus fiber shell. The fiber for the fill is made using the wood pulp from eucalyptus trees while the shell is made with eucalyptus lyocell, a type of rayon similar to bamboo-based fiber. All of the eucalyptus fiber in the Buffy Breeze is OEKO-TEX certified to ensure it contains no harmful substances.

The 300 single-ply thread count shell fiber gives the duvet insert an extremely soft feel. The Buffy Breeze is constructed with a wave stitch pattern that helps keep the fill materials evenly distributed throughout the duvet insert. It also contains sewn loops on each corner to accommodate duvet cover ties and help keep your duvet insert in place.

The only downside to the Buffy Breeze is that it’s not easy to clean. While some duvets can withstand machine washing, Buffy recommends that you dry clean the Buffy Breeze. Using the Breeze with a duvet cover will help to extend the amount of time before you’ll need to clean it again.

Your purchase of the Buffy Breeze comes protected with a 7-day trial. If you choose to return the Buffy Breeze within the trial period, you won’t be charged for your purchase. You also have 30 nights from the time your order was placed to initiate a free return for a full refund.

Duvets can be an indispensable sleep accessory in cold weather, but they tend to cause overheating during warmer times of the year. The aptly named Casper Humidity Fighting Duvet features a cotton shell lined with merino wool. The cotton is breathable and merino wool has natural moisture-wicking properties, so these materials essentially form a cooling barrier between your body and the duvet’s plush down fill.

Two weights are available for the duvet. The mid-range option is best suited to areas prone to chilly winters and mild summers, while those who reside in hot or humid locales may feel more comfortable with the lightweight duvet. All versions feature sewn-through baffle boxes for even fill distribution and less clumping, so you shouldn’t need to fluff the duvet too often. You can wash and dry the duvet in your household machines for easy, convenient care.

The Humidity Fighting Duvet is available in twin/twin XL, full/queen, and king/California king sizes. Casper offers free ground shipping to all customers in the contiguous U.S. and provincial Canada. Each order includes a 30-night trial for testing out the duvet, and a 1-year warranty against manufacturing defects for those who keep it after the trial period expires.

Lab Notes – What Our Testers Thought

“The Humidity Fighting Duvet is impeccably constructed – certainly a more advanced design than you’ll typically find with a standard down comforter. The merino wool is a nice touch for hot sleepers.”

The Leesa Duvet Insert is well suited to people who enjoy sleeping with a comforter throughout the calendar year. Down alternative fill makes the insert plush and lofty without feeling too heavy or retaining excess body heat, while the shell is composed of breathable organic cotton. The result is a mid-weight layer that offers ample coziness during colder times of the year but is also comfortable for hot weather.

The fill is completely synthetic, and won’t trigger symptoms for those who are allergic to real down. The material composition should also appeal to people who prefer not to purchase products with animal components. The cotton shell has a smooth feel for sleepers with sensitive skin, as well. The perimeter is reinforced to prevent tears and rips that can allow fill to escape.

Three sizes are available: twin/twin XL, full/queen, and king/California king. The insert can be washed and dried in any household machine, making it more convenient to clean than many competing comforters – particularly those with down and feather fill.

In terms of sticker price, this duvet insert is on par with its competitors. Leesa provides free ground shipping to customers in all 50 states and allows returns within 30 days of the delivery date.

Lab Notes – What Our Testers Thought

Why You Can Trust Us

Our team of experts tests bedding products to help you create the perfect sleep environment. We’ve tried dozens of comforters and duvet inserts and narrowed them down to our top picks based on thorough in-person evaluations.

How We Evaluated These Duvet Inserts

Each member of our testing team has extensive experience reviewing sleep products and they understand which factors are important to our readers. In our sleep lab, the product testers personally use each duvet insert and examine its insulation, fill, airflow, and durability. The sleep product experts have different body types, sleep styles, and personal preferences. This diversity allows us to provide you with recommendations that are specifically catered to your needs.

What is a Duvet Insert?

A duvet, derived from the French word for down, is a type of bedding that consists of a duvet insert and a duvet cover. The duvet insert is made up of an enclosed fabric shell filled with a soft, lofty material. While the traditional choice for fill material has always been goose or duck down, it’s now easy to find duvet inserts made with a variety of materials from synthetic options to other natural choices like wool and silk.

Duvet inserts typically come in a neutral color such as white or cream. Similar to a pillow and a pillowcase, duvet inserts are placed in a duvet cover. The cover protects your duvet insert from body oils and stains. For this reason, many choose to forgo a top sheet when sleeping with their duvet.

Duvet inserts come in a wide variety of sizes, weights, and materials. The best duvet insert for you will depend on your personal preferences and the level of warmth you need from your bedding. It’s also important to note that the quality of the materials you choose will have a significant impact on the durability and overall performance of your duvet. We’ll help you determine how to choose the best features for your needs and the best materials for your budget.

What’s the Difference Between a Comforter and a Duvet Insert?

Bedding terminology can be confusing and many people mistake duvet inserts for comforters or believe that the two terms are interchangeable. However, there are a few key differences between these two types of bedding.

First, let’s address the similarities. Both comforters and duvet inserts are commonly filled with down or synthetic materials and are meant to keep you warm at night.

Now the differences. The most important differentiator between comforters and duvet inserts is that comforters are designed to be used without a case or cover. That’s why comforters are often available in more colorful options and are commonly paired with a top sheet for protection.

How to Choose a Duvet Insert

A duvet insert makes up the core of a duvet, a unique style of bedding designed to keep you warm on cold nights. Originating in Europe, a duvet consists of a duvet insert, a fabric shell filled most commonly with down, and a duvet cover, an additional fabric layer that protects the duvet insert from dirt and can be removed for easy cleaning

As you search for a new duvet insert, you’ll be presented with a wide variety of options. Here we’ll discuss the most important factors to consider as you shop for the best duvet insert.

What to Consider When Purchasing a Duvet Insert

When shopping for a duvet insert, you may start to feel overwhelmed by the sheer amount of options you have to choose from. Additionally, bedding companies can sometimes use misleading language that makes it difficult to decipher the most important differences between products.

We’re here to help you cut through the noise and figure out which duvet insert is best for you. The key factors to consider are the materials, size, weight, design, price, and temperature regulation.

Key Points
  • Quality Materials
    The type of materials used in the construction of your duvet insert will have the greatest impact on its overall performance and durability. This includes both the fill material and the shell material. Down is the traditional choice for duvet insert fill material. It also tends to be the most expensive and durable fill material available. However, high-quality forms of synthetic down alternatives such as Primaloft can rival the loft and warmth of down. When it comes to the shell material, cotton and polyester are both quality fabrics, but polyester tends to be more durable.
  • Size
    Duvet inserts are typically available in sizes that are compatible with the most common bed sizes including twin, twin XL, full or double, queen, king, and California king.
  • Weight
    The weight of your duvet insert is an important consideration and will depend on the climate you live in and your own personal preferences. For cold sleepers in cold climates, a heavyweight insert is the best choice. If you live in a warmer climate but enjoy the comfort of a plush duvet, consider a lightweight duvet insert. You can also purchase different duvet inserts for different seasons and rotate them throughout the year.
  • Design
    Duvet design refers to how the insert was constructed in terms of its stitching. Although this may seem like a purely aesthetic detail, the design has a significant impact on how the fill material and therefore heat insulation is distributed throughout the surface area of your duvet insert.
  • Price
    The price you pay for your duvet insert can vary significantly and will depend largely on the type of fill material you choose as well as the size. Prices can range from $100 up to $1,000. At the lower end of this range are duvet inserts that use synthetic or synthetic blend materials. The top end of the price range consists of ethically harvested down and organic wool.
  • Temperature Regulation
    Although duvets are meant to keep you warm at night, no one wants to wake up in a sweat. Certain materials are better at regulating your body temperature throughout the night, especially if you tend to sleep hot. Down is the most insulating fill material and is more likely to allow heat from the body to build up during the night.The best duvet inserts for hot sleepers and the best cooling duvet inserts tend to be made from materials that are more breathable than down including silk, cotton, and synthetic fibers.

What Are the Pros and Cons of Duvet Inserts?

Duvet inserts are one of the warmest bedding options available, but they can be difficult to clean. Let’s take a closer look at the most significant pros and cons of duvet inserts.

Pros Cons
  • Duvets offer higher insulation than many other types of bedding. They also typically come in higher lofts, so you won’t need to pair them with extra sheets or blankets.
  • Duvet inserts don’t require frequent cleaning. The duvet cover, which can be removed and cleaned, protects the duvet insert from stains and body oils.
  • Although duvet inserts are usually plain in color, you can switch out duvet covers with different patterns and styles.
  • Duvet inserts have many options for fill material depending on your needs. Gone are the days when down was the only game in town. Now you can find duvet inserts made from synthetics, other natural fibers like wool, and even ethically sourced down.
  • Duvets can be difficult to clean and may require dry cleaning or other costly professional cleaning options. Unlike a blanket, if your duvet becomes badly stained, you may need to replace it.
  • The additional cost of a duvet cover adds to the overall expense of using a duvet insert.
  • Duvet inserts can be tricky to place inside their cover and are prone to bunching up inside their covers after repeated use.

    What Types of Duvet Inserts are Available?

    Different types of duvet inserts can be categorized by the fill or the material inside the duvet insert that gives the bedding its loft. In terms of fill material, the overall quality of the material matters more than the material itself. However, certain materials are considered more of a luxury, a feature reflected in the price tag of premium duvet inserts. Additionally, different types of materials have different advantages and disadvantages. Here we’ll take a detailed look at the different types of fill materials commonly used in duvet inserts.

    Down: This is the traditional choice for duvet insert fill material. Many people associate down with the feathers of a duck or goose. While quilled feathers are water-resistant and help these birds fly, down actually sits below the feathers.

    Down is light and fluffy and provides insulation and warmth in cold conditions. Duvet inserts made with down can be more expensive, but if you live in a cold climate, down filling is often the best choice. Just be aware that for certain sleepers, down may trigger an allergic reaction.

    Synthetic Down Alternatives: Aside from down, synthetics are the most common fill material used in duvet inserts. Polyesters and other synthetic fabrics are designed to mimic the fluffy feel of down. For those with allergies or who prefer to stay away from animal products, synthetic down alternatives offer a good compromise. Synthetics can be less expensive than genuine down, but the lower in price you go, the more you’ll sacrifice in terms of durability and overall quality.

    Wool and Silk: If you’re looking for a natural material, you can also find duvet inserts made from wool or silk. Wool provides a warm, moisture-wicking alternative to down, but it won’t provide the same loft. Silk is perfect for those living in warmer climates or as a lightweight duvet for the summer months.

    Although your duvet will be wrapped in a duvet cover, the shell material can still have an impact on performance. Cotton and polyester are the most common shell materials. Both are affordable, but cotton tends to be more breathable while polyester can be more durable. For the best of both worlds, try a cotton-polyester blend, a fabric that offers the best features of each material.

    Frequently Asked Questions

    • What is a duvet insert?

      A duvet insert is a type of blanket that’s meant to be used with a cover. Typically, an insert has two parts: an insulated fill and a shell that wraps around it. Down is perhaps the most widely known type of fill, but you can also find duvet inserts that feature synthetic down alternatives, wool, silk, or blends.

      What separates a duvet insert from a comforter or other type of blanket is that it’s intended to be used with a cover. This allows you to go longer between washes, which can be particularly helpful for inserts that are dry clean only. A cover also allows you to easily change the look of your bedding since they are often compatible with a wide range of inserts.

    • What's the best way to wash a duvet insert?

      The exact method for washing your duvet insert will vary depending on what it’s made out of as well as the manufacturer’s recommendations. The fill and shell materials will dictate how to appropriately care for your insert, as some are machine-washable while others require dry cleaning. Which size you choose is also a factor, since larger inserts may have too much volume for a home washing machine and will require a commercial washer.

      Using a duvet cover is one of the best ways to help preserve your insert’s lifespan. Covers are usually made from washable fabrics that help decrease how often you have to launder your insert. Because the cover is what comes into contact with your skin rather than the insert, some sleepers choose not to use a top sheet.

    • How do you insert a duvet?

      We’ve found the easiest method for putting a cover on your duvet insert is the inside-out method.

      1. Lay your duvet insert on top of your bed.
      2. Turn your duvet cover inside out, slide your arms inside the cover. With your arms inside the cover, grab the bottom corners of the cover.
      3. Still holding the corners of the cover, also grab the top corners of your duvet insert.
      4. Making sure to hold on tightly, begin to flip the duvet cover right side out and over your duvet insert. It may take a bit of shaking and fluffing before the cover falls down to encase the entire length of the insert.
      5. Let go of the corners, and finish by stuffing the opposite corners of your duvet insert into the open side of your cover, checking to see that everything is aligned.
      6. Zip or button your cover closed.
    • How can you keep a duvet insert in place?

      Duvet inserts typically use buttons, ties, loops, or snaps to help fasten the insert to the cover at all four corners. For example, a duvet insert with loops and a cover with buttons can easily be attached when you push the buttons through each corner loop. Since lots of sleepers mix and match their covers and inserts, many models are equipped to work with different fasteners.

      Some duvet covers lack internal ties to keep the insert in place. You can use small safety pins to secure the top corners of your duvet insert to the inside corners of your cover before putting on the cover. Matching the cover and insert at each corner ensures that the insert doesn’t migrate or bunch up during the night.

    • How much do duvet inserts cost?

      A duvet insert may cost as little as $50 or upwards of $1,000. The price will vary greatly depending on the type of materials used, the quality of those materials, and the construction. Duvet inserts that use synthetic fill tend to be more affordable than duvet inserts made with down.

      The source also matters. Expect to pay more for anything containing organic cotton or wool and ethically-sourced down.

    • How long do duvet inserts last?

      A quality duvet insert should last for several years for most sleepers, often up to or beyond 10 years. Duvet inserts tend to last longer than pillows as they lay on top of the sleeper and don’t need to support your body weight. Keeping your duvet insert protected with a frequently washed cover will help extend its lifespan.

      The lifespan of your duvet insert is directly affected by its materials and construction. Synthetic duvet inserts tend to lose their loft and ability to insulate faster than down-based duvet inserts. In fact, well-made and well-maintained down duvet inserts can typically last upwards of a decade or more.

      Lastly, your sleep habits can also affect the longevity of your duvet insert. Sleepers who toss and turn consistently or sleep on top of their duvet will wear out its loft and insulation more quickly.

    • Which size duvet insert is right for me?

      Purchase a duvet insert that corresponds to the size of your mattress. Inserts are typically available in standard sizes from twin up to California king. If you prefer extra bedding material or own a high-profile mattress, consider going up one size from your mattress size. Couples who toss and turn or who have different sleep temperature preferences should also consider purchasing two smaller duvet inserts and covers so each person can have their own bedding.

    • Where can I buy a duvet insert?

      Duvet inserts are easy to find online and at big box stores. While some shoppers enjoy the hands-on experience of shopping for bedding in person, shopping online will give you the most options to choose from. Plus, most reputable online bedding retailers today offer generous return and warranty policies.
