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 Brooklinen Down Comforter is made in Canada using ethically sourced down harvested from Europe and Canada. With premium, high-quality materials and multiple warmth options, the Brooklinen is an excellent pick for a wide variety of sleepers who prefer down.
Made with 100% down cluster fill, the Brooklinen has all of the best features of a down-based duvet including cloud-like loft and incredible insulation power. The fill material is treated with an antimicrobial to help prevent the growth of bacteria or mold and keep your bedding fresh. The outer shell of the Brooklinen is made with soft and breathable 100% long-staple cotton sateen.
The Brooklinen also comes in more than one weight. The all-season weight is made with 700 fill power down that’s extremely warm and lofty. However, for those who sleep warm or live in a slightly warmer climate, the lightweight option contains a 650 fill power down that’s a bit cooler. The ultra-warm weight is constructed with 750 fill power to keep sleepers warm on colder nights.
The Booklinen is designed with baffle box construction to keep the down fill in place. Loops are sewn into every corner to act as tie-in points for a duvet cover.
Brooklinen recommends spot cleaning stains. You should also periodically hang your down duvet outside on a dry day or use a dryer on the no-heat setting to dry it out.
Brooklinen also provides one of the most generous return policies in the industry. Most products can be returned or exchanged within 365 days for free with a full refund.

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 TX, 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.
Use this SleepFoundation.org link for the most current discount on Buffy bedding
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 seven-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.

The Down Alternative Duvet from Silk & Snow is a cozy duvet insert with thoughtful construction and a competitive price-point. The duvet is available in an “all season” and “winter” weight option, but both carry the same affordable price tag.
The duvet is filled with a down alternative microfiber that mimics the plush feel of real down but does not trigger allergies that down is known to do for some sleepers. The 100% cotton shell is breathable and lightweight, and square stitching across the duvet prevents the fill from bunching up. The all-season option has a fill with 375 grams per square meter (gsm), which should feel quite comfortable throughout the year. For those who live in cool climates or who need a heavier duvet for colder months, the winter option has a 500 gsm fill.
The down alternative fill is derived from recycled plastic bottles, making this an appealing option for shoppers who are concerned about eco-friendly sourcing. The duvet is also a good choice if you enjoy the feel of down but prefer bedding that contains no animal-based products. The entire duvet is machine-washable. Silk & Snow recommends washing on a cold cycle and tumble drying on low.
Silk & Snow offers free shipping and returns throughout the contiguous U.S. and Canadian provinces. The duvet is backed by a 100-night sleep trial as well as a 1-year warranty.
Save 10% off your cart with code SF10
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.

Eco-conscious shoppers searching for an all-season 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 life-span thanks to its double-stitched edges. Sleepers can attach the insert to a duvet cover using corner loops.

The White Goose Down Duvet from Peacock Alley is luxurious and practical in equal measure. The fill consists of plush down clusters, creating an exceptionally cozy and lofty feel, but a fill power of 650 and the breathable cotton sateen shell ensure the duvet won’t overheat too much in warmer weather. These qualities make the duvet particularly well suited to places with mild or temperate climates. Depending on which size you choose, the duvet weighs between 20 and 35 ounces.
The baffle boxes are sewn through to keep the down in place and prevent it from shifting or clumping to one side. Prior to production, the down is cleaned and sterilized to ensure the fill is not contaminated with harmful bacteria. The cotton has a very smooth feel and is conducive for people with acne, rashes, and other skin sensitivities. For care, you should either have the duvet dry-cleaned or launder it in a commercial washer.
Twin/twin XL, full/queen, and king/California king sizes are available.

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.
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.
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.
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.
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 can both comprise quality fabrics, but polyester tends to be more durable.
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.
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.
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 to 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 create a fluffy material that mimics the feature 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.
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.
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.
We’ve found the easiest method for putting a cover on your duvet insert to be the inside out method.
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.
A duvet insert may cost as little as $50 or upwards of $1000. 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.
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.
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.
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.
