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.

Saatva’s reputation for luxurious sleep products extends beyond the company’s mattress line. Take the All-Year Down Alternative Comforter, which is constructed with premium materials and – as the name implies – is designed for use in any season. The fill consists of animal-free down alternative clusters blended with lyocell fibers. This creates a lofty and comfortable feel reminiscent of real down, but without triggering allergy symptoms.

Lyocell is highly breathable and has moisture-wicking properties, so the comforter shouldn’t sleep excessively warm in hot or humid temperatures. Another cooling component is the shell, composed of organic cotton with a crisp percale weave. The cotton has received a Fair Trade certification, ensuring the workers who grow and harvest the fibers are ethically treated and compensated with reasonable wages.

A box-quilted design with small baffles helps to distribute the fill evenly, so clumping and shifting shouldn’t occur. You also won’t need to fluff the comforter too frequently. Corner loops allow you to attach the insert to any duvet cover. Twin/twin XL, full/queen, and king/California king sizes are available. The entire comforter can be washed and dried in household machines.

Saatva ships the All-Year Down Alternative Comforter free of charge to customers in the contiguous U.S. Your order includes a 45-night sleep trial, as well as a 1-year warranty against structural defects should you decide to keep the comforter.

Lab Notes – What Our Testers Thought

“The All-Year Down Alternative Comforter lives up to its name. Plenty of insulation from the cold, but also light and breathable enough to keep you cool in warmer temperatures.”

Quince is known for its quality bedding and approachable price-points, and the All-Season Premium Down Comforter is no exception. The comforter offers a luxurious feel and durable construction that should feel comfortable through all seasons and in all climates.

The comforter contains 650 fill power classic white down, which provides plenty of warmth for cooler nights but is also fluffy and lightweight enough to avoid overheating. The fill is encased in a shell made of breathable 100% cotton with a sateen weave that feels silky-soft and cool against the skin. Baffle-box stitching keeps the fill in place and ensures that it won’t clump over time. If you use a duvet cover, corner loops anchor the comforter inside the cover to prevent it from shifting and bunching up during the night.

If you like the feel of down but are concerned about ethical sourcing, the fill has Responsible Down Standard (RDS) certification to ensure it adheres to standards for the humane treatment of animals. You may machine wash the comforter in cold water on a gentle cycle and tumble dry on a low heat setting.

Quince offers free shipping within the U.S. Customers receive a 365-night sleep trial to try out the comforter.

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 and highly comfortable 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 insert 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 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. Shipping is free for customers in the contiguous U.S.

Sleep Foundation Exclusive Offer!

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 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.

Sleep Foundation Exclusive Offer!

SleepFoundation.org readers get 15% off their purchase with code: SLEEPFOUNDATION

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.

Use this SleepFoundation.org link for the most current discount on Nectar bedding

Duvets can be an indispensable sleep accessory in cold weather, but they tend to cause overheating during warmer times of the year. The Nectar Duvet features a breathable cotton shell and down alternative fiberfill that offers cozy warmth while retaining less heat than traditional down. The fill also uses Climasmart cooling technology meant to regulate temperature while you sleep. Thanks to these features, we recommend this pick for year-round use and for those whose temperature needs change night-to-night.

The down alternative fibers mimic natural down’s lofty feel without the dust and potential allergens. Sewn-in baffle boxes keep the fill evenly distributed and prevent bunching near the feet, so you shouldn’t have to fluff it very often. The duvet is fully machine-washable, provided your appliances are large enough to accommodate it.

You can choose between twin, twin XL, full, queen, king, and California king sizes. Along with the approachable price-point, Nectar ships free to customers in the contiguous U.S., and returns are permitted within 30 days of delivery. Duvets are backed by a 1-year warranty against structural defects.

Lab Notes – What Our Testers Thought

The shell is made of 100% cotton in a smooth sateen weave that feels silky to the touch. The fill is composed of proprietary VirtuDown, a down alternative material that mimics the loft and fluffiness of down but is not derived from animals. The VirtuDown excels at keeping you warm on cooler nights, while the lofty feel prevents the kind of heat retention that can result from heavier comforters.

The baffle box construction ensures the fill stays evenly distributed without clumping, and double-stitching promotes overall durability. The insert has corner loops that you can secure to your duvet cover so that the insert does not bunch up overnight. Satin piping around the edge adds a touch of elegance. You may wash the insert in front-loading machines using cold water on a gentle cycle. Dry thoroughly on a low heat setting.

Pure Parima gives you 100 nights to try out the duvet insert. You may return the insert during this timeframe for a full refund. The insert also comes with a 2-year warranty. Shipping is free to all 50 states.

The Cozy Earth Bamboo Comforter is one of two comforter options available, both of which offer exceptional breathability. The bamboo version is composed entirely of viscose derived from bamboo, a material touted for its luxuriously soft feel that can soothe sensitive skin. All of Cozy Earth’s products are made from sustainably sourced materials, making the comforter a great choice if you’re willing to spend more on an eco-friendly product.

Bamboo-derived fabrics are known for their cooling and moisture-wicking properties that cater to hot sleepers and people living in warm or humid locations. You can also opt for a silk version of the comforter for a fluffier, down-like feel. Both the bamboo and silk models come in two fill volume options: standard and extra. The standard option is lightweight but insulates a comfortable amount of warmth, so we recommend it for year-round use. The extra weight is excellent for winter use or if you live in a cooler climate.

The comforter is fully machine-washable. Cozy Earth recommends only using a rinse cycle and drying on low heat with a few tennis balls to prevent the fill from clumping. Three sizes are available – twin, queen/full, and king – and all are intentionally oversized to fit most mattresses.

If you live in the contiguous U.S, you’re eligible for free shipping. Cozy Earth offers a 100-night sleep trial with your comforter purchase, during which you can return it for a full refund. The Bamboo Comforter is backed by a 10-year warranty against structural defects.

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 top layer of bedding meant to keep you warm throughout the night. The duvet consists of two parts: 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, while a duvet insert is used with one. That’s why comforters are often available in more colorful options and are commonly paired with a top sheet for protection. However, some people use a comforter as a duvet insert and pair it with a duvet cover for easy washing.

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: A down duvet insert, also called a duvet, is a widely known and popular choice. 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.
