Everyone needs bedding, but with so many options on the market, it can be overwhelming to pick out a product worthy of spending a third of your life with. And on top of that, if you’re looking for bedding that's vegan-friendly and hypoallergenic, it can feel like a near-impossible feat. Enter down-alternative comforters—the modernized and more sustainable counterpart to traditional down comforters you know and love.

Whether you're interested in bedding made from recycled materials, have a feather allergy (no duck or goose feathers here!), or are looking for a reasonably priced substitute to traditional down, a down-alternative comforter is an excellent choice. 

After hours of research, we gathered 30 top-rated down-alternative comforters on the market and put them to the test in The Lab and in our homes. We evaluated them based on their quality, texture, breathability, durability, and overall value. During our testing process, we paid special attention to fiber content, ease of care, and any temperature-regulating properties.

Editor's Note: This article was revised in September 2023 with new product picks and long-term testing insights. 

What to Know Before You Get Started

Down-alternative comforters typically come in two specific designs, or construction styles, that speak to how their fluffy fill is arranged and kept in place:

  • Sewn-Through Comforters: The top and bottom layers of the shell are attached to one another, which prevents the fill from shifting between each section. However, this design is less lofty than baffle box comforters and cold air may seep through the seams. 
  • Baffle Box Comforters: These have a strip of fabric separating the top and bottom layers, which creates a three-dimensional form that can trap and retain more heat. With a baffle box construction, you'll have to regularly shake out your comforter to prevent the fill from clumping.

What We Like
  • Made from recycled materials

  • Lightweight yet warm

  • Soft and smooth shell

What We Don't Like
  • Not dryer-friendly

Of all the options we tested, our number-one pick is the Buffy Cloud Comforter. It earned high marks during our lab tests, as we were huge fans of its soft and smooth texture, top-notch temperature regulation properties, and lofty construction.

Ideal for year-round use, this down-alternative comforter has the Goldilocks touch of being just right thanks to the fact it's breathable and airy, while still being plenty plush and cozy. We also loved how easy this comforter was to move around and fold, as making the bed each morning was a breeze. Plus, the down alternative appeared smooth and even throughout with no pesky lumps.

We're huge fans of the buttery-smooth shell and lightweight yet substantial fill. The fill is a synthetic polyester, which is sourced from upcycled plastic bottles. The lyocell shell comes from the pulp of eucalyptus trees, and the 300-thread count sateen weave gives it that ultra-smooth texture.

Compared to other comforters that tested similarly in the lab and at home, this product is value-packed considering its impressive quality and high-end construction. Rather than a baffle-box or sewn-through design, the Cloud Comforter is made using Buffy’s unique stitching pattern that claims to keep the fill in its place. We also like that it's machine-washable, but bear in mind that hang-drying is recommended.

How It Performed Long-Term

We've tested this duvet cover in our homes for six months, and we're happy to report that it continues to impress. This soft and silky pick has proved to be suitable for year-round use, as it's not overly thick but traps in enough warmth to keep us comfortable on colder nights. And even during the spring and summer months, we've had no issues with overheating. After numerous rounds in the wash, we've found that its texture, appearance, and performance haven't changed at all. What's more, Buffy's proprietary stitching design has kept the fill perfectly in place throughout the testing period.

  • Breathable and lightweight

  • Several colors available

  • Easy to clean

What We Don't Like
  • Colors can vary slightly

The Quilted Comforter from Utopia Bedding earned perfect scores across the board, making it our favorite budget-friendly pick. We appreciated its breathability, cozy warmth, machine-washable design, handy corner loops, and impressive value. This baffle box comforter comes in six exact sizes, so you won't have to worry about excess fabric hanging off your duvet cover. Many of our other picks straddle the line between a Twin and a Twin XL, or are the same size for a Full and a Queen. 

In addition to white, it comes in eight other pretty color options, so if you're not a fan of duvet covers, you can go without one and just rock one of these chic hues. Just be aware that the colors may slightly vary from how they appear online.

While this isn't the loftiest comforter on the market, it's an excellent lightweight option that's exceptionally breathable and suitable for those who tend to sleep warm. We really enjoyed its airy feel, which kept us from overheating and made the comforter easy to fold and move—it would be great for a college dorm given all the moves your student might have to do while keeping them plenty cool in air condition-less dorm rooms. Additionally, we found it was exceptionally simple to wipe away any stains with just a damp towel.

How It Performed Long-Term

After months of real-world testing, we can't recommend this product enough. We used this product consistently in our homes for six months, and it's still performing up to our standards with no signs of wear and tear. This pick might not be the heftiest option on our list, but we've found that it still does a great job of keeping us warm on cooler nights.

What We Don't Like
  • Difficult to maneuver

  • Not machine washable

If you're open to splurging on a truly opulent bed cover, Cozy Earth won't let you down. This entire comforter, including both the shell and fill, is made of bamboo-sourced viscose. In our tests, we found the material to be exceptionally breathable and luxuriously soft.

What's more, we loved the shell's temperature-regulating and moisture-wicking abilities, which make it perfect for people who run hot or experience night sweats, though it's also plenty warm. And if you prefer a little more weight, upgrade to the "extra" fill level. Though heavy, the shell still felt breathable, and we had no issues in terms of overheating. However, it can be a bit hard to maneuver because of the extra weight.

How It Performed Long-Term

Breathable, durable, and ultra-soft, we're happy with the general performance of this comforter over the span of six months. Even during the summertime (and 90 degree-plus nights), we’ve appreciated how cool it kept us throughout the night, which can be especially helpful if you tend to sleep warm. We also love that the fill hasn't shifted and has stayed fluffy throughout the testing period.

While this comforter has impressed us on almost all fronts, we don't love how tedious the care instructions are, as you won't be able to simply toss this comforter in the wash if it gets dirty. And, it’s the most expensive pick on our list. That being said, if you're willing to put in the extra effort to maintain this high-end product, we think it's definitely worth purchasing.

  • Even and noisless fill

What We Don't Like
  • Not very lofty

Finding the right comforter is hard enough, but finding the perfect size and color can feel impossible. For a great selection of sizes and colors, we recommend the Cohome Down Alternative Comforter, which also works as a duvet insert. It comes in seven sizes, including oversized king and queen, and five colors.

Aside from the notable size and color selection, we loved its high-quality and thick material, which is especially impressive given its affordable price tag. The cozy polyester fill is designed to be evenly distributed and noiseless thanks to its baffle-box construction, which is especially ideal for restless sleepers.

We also love that this comforter is machine washable and dryer safe. During our tests, we did find that it's not as thick or lofty compared to some other options we tested, so this may not work if you prefer a heavier comforter. However, if you're looking for a more lightweight option to sleep with, this could be perfect.

How It Performed Long-Term

The Cohome Down Alternative Comforter has held up well during the course of our three-month testing, ranging from cool November weather to frigid temperatures in January. We’ve found that it does lack a little bit of heft that you may need during the winter, but you can just add a quilt or blanket to your bed to boost that warmth. It’s a great option for spring and summer months as its lighter weight prevents it from feeling too stifling at night, which we appreciate. The fill has also stayed even throughout the testing period.

Calling all hot sleepers! The HydroCool Duvet Insert from Pottery Barn boasts an incredibly soft shell, lightweight yet cozy feel, and machine-washable design. We were thoroughly impressed with its temperature-regulating abilities when testing the down-alternative comforter at home and in the lab. 

The comforter has proved to be exceptionally versatile, as it feels relatively cool in the summer while keeping us toasty in the winter. In our experience, it delivers the perfect amount of warmth no matter the temperature—making it suitable even in chillier climates. However, if temperatures get extremely cold, you may have to supplement the comforter with an additional blanket. But on most nights, the HydroCool Duvet Insert kept us at a comfortable temperature all night long.

Upon first inspection, we were impressed with how luxuriously soft the material felt. Plus, the comforter was easy to maneuver and move around since it wasn't too heavy. This down-alternative comforter has a breathable cotton shell with a 300 thread count to ensure adequate airflow. The fill is 60 percent recycled polyester sourced from plastic bottles and 40 percent HydroCool performance polyester. According to the manufacturer, the high-tech fibers also draw sweat away from your skin so you stay cool throughout the night.

  • Breathable and cool

What We Don't Like
  • No corner ties

Down-alternative duvets are suitable for year-round use, as long as you make sure that you're not purchasing one that is on either end of the weight scale. With this in mind, we recommend Coyuchi's Climate Beneficial Wool Duvet, which is both cool to the touch and insulating. Unlike other options we tested, this pick is more dense than it is lofty, but we found the weighty construction to be exceptionally comfortable. Despite its density, we found this comforter to be very breathable and temperature-regulating, making it the optimal great all-season pick.

In terms of construction, this duvet has a 100 percent GOTS Certified organic cotton shell and wool fill. Upon inspection, we found it to be very well made with a luxuriously soft texture. When testing for durability, we stained the comforter with coffee and treated it with a wet towel and Tide Pen to see how easy it was to clean. While the stain was not completely removed during spot treatment, you can easily refresh this comforter by tossing it in the washing machine and letting it air dry.

Prefer something a bit lighter than our previous pick? Your best bet is Tekamon's All-Season Comforter. Upon initial inspection, we were impressed with the product's brushed microfiber shell, which felt exceptionally soft. In our testing, we also found the material to be very breathable and cooling.

The super-fine polyfill is designed to mimic the natural fluffiness of real down, and it was quite insulating despite not being the loftiest pick we tested. We appreciate that this duvet insert is available in plenty of sizes as well as several color options. We also love its easy care instructions, as you can simply throw the comforter in the washer and dryer when it's time to clean it. In the lab, we found that the coffee stain was removed without much effort, using just a wet cloth to spot clean.

What We Don't Like

Not too warm but still plenty cozy, Sijo's Temptune Comforter is ideal for year-round use. The fill fibers are made of the company's patented Clima fiber blend that aims to regulate your body temperature. In the lab, we found the construction quality of this comforter to be quite high-end, with a medium weight, a smooth and soft fabric, and no signs of imperfections throughout.

The shell is made of Tencel lyocell that's sourced from the pulpy cellulose fibers of wood and mica nylon. Because of the Tencel's natural temperature-regulating properties, it offers the perfect amount of warmth without causing you to overheat. When laying underneath the comforter, we liked that it provided a substantial and even weight, trapping in warmth without causing us to overheat. Although this comforter impressed us with its performance overall, we think it's worth noting that we had a bit of trouble spot-cleaning the coffee stain in the lab. Additionally, this comforter is dry-clean recommended, which may pose an issue in mess-prone households.

The Boll & Branch Down Alternative Duvet Insert comes in three densities, and the ultraweight level is one of the warmest, coziest options you'll find. It's filled with PrimaLoft microfiber, a hypoallergenic material that boasts thermal qualities and down-like loftiness—you’ve likely seen PrimaLoft in winter jackets, pillows, and even footwear. As for the shell, you're looking at 100 percent organic cotton

Thanks to the baffle-box construction, the comforter is extra lofty and airy. We also appreciate that there are corner tabs to keep your duvet cover in place.

Supremely soft, lightweight, and stylish, you'll love Linenspa's All-Season Down Alternative Comforter. It earned a perfect score in terms of quality during our lab test, as we found no imperfections throughout and were impressed with its overall construction. Made with a polyester fill and microfiber shell, we love its buttery-smooth and soft texture. While it's not as lofty as some other options we tried, we found it exceptionally comfortable, noiseless, and easy to maneuver around the bed. Additionally, we loved how cool it was when laying underneath it, making it a great option if you tend to sleep warm.

It's available in six color options, meaning it still looks great even if you don't want to use a duvet cover. In fact, it even boasts a reversible design with different colors on either side to add more dimension to your bedscape. And no worries if you get your comforter dirty—simply toss it in the washer and dryer when it needs a refresh.

Vesta

What We Like
  • Silk fill material

  • Exceptionally soft

  • Temperature-regulating

  • Moisture-wicking

What We Don't Like
  • Tedious care instructions

Silk material is naturally breathable and moisture-wicking with unique thermal stability, so it keeps you warm when you want it to and cool when it’s hot. Plus, if you prefer natural materials over polyester, this one from Vesta is worth your attention. Vesta's Thermoregulating Duvet is filled with 100 percent premium-quality silk fibers. One thing to note, though, is that it's not vegan-friendly, as the silk comes from mulberry worms.

This down-alternative comforter has an organic cotton shell to encourage airflow. Thanks to its temperature-regulating abilities, it's an excellent choice for year-round use. And while we think this ultra-luxe comforter is a great pick for most households, we do want to note that the care instructions are quite tedious, which may not be best suited for those with kids or pets. The manufacturer advises that any stains or spills should be wiped down and doesn't recommend putting it in the washer or dryer.

Final Verdict

The best down-alternative comforter on the market is Buffy's Cloud Comforter, which earned an almost-perfect score in our lab testing for its ultra-soft shell and lightweight yet substantial fill. If you're looking for something even more wallet-friendly, we recommend the Utopia Bedding Quilted Comforter, a machine-washable, exceptionally snuggly comforter that comes in several colors.

How We Tested

To compile this list, we researched highly-rated and best-selling comforters from a wide range of retailers. We then purchased over 30 of the most recommended and popular picks to put to the test at The Lab in Des Moines, Iowa. First, we evaluated quality by inspecting each comforter upon arrival. We paid attention to the type of construction, the quality of the seams, the height of the loft, and the distribution of the fill throughout the comforter. Additionally, we noted how easy the comforter was to maneuver when making the bed, how noisy it was when handling it, and the general weight. Next, we assessed the texture by taking note of the shell material, thread count, and weave, noting how soft each felt when lying underneath.

To test breathability, we laid underneath each comforter for five minutes and noted the amount of airflow the comforter allowed through as well as its loft and any temperature-regulating abilities. To evaluate durability, we followed care instructions, noting changes in loft height, distribution of fill, or other signs of wear. We even spilled coffee on each comforter to see how easy it was to remove stains. Finally, we assessed each comforter's overall value by comparing retail prices with overall quality. We even long-term tested some of the options to see how they held up in real-world scenarios over the course of one, three, and six months. With those insights and our research, we chose our favorites to highlight on this list.

What to Look for in a Down-Alternative Comforter

Shell Material

High-quality materials are paramount for down-alternative comforters, starting with the shell (the outside of the duvet). Natural fabrics tend to be the most breathable with moisture-wicking properties, which helps keep you at a comfy temperature while you doze. Cotton is the most common, but you'll also find options with bamboo, eucalyptus, silk, and lyocell shells. Consider investing in comforters made with high-end materials, including the Coyuchi Wool Duvet Insert, our best all-season pick, which is made with wool and organic cotton, or the silk-covered Vesta Thermoregulating Duvet. Wool, cotton, and silk are known for their luxurious comfort and durability, which typically offer a longer lifespan than their synthetic counterparts.

Synthetic shell fabrics can sometimes mean a less soft comforter than a natural material. However, synthetic materials often lead to lower prices, which is part of the reason why the Utopia Bedding Comforter earned a spot on our list. Additionally, synthetic materials have their own set of benefits compared to natural materials, such as higher stain resistance, easier care instructions, and resistance to shrinkage.

In addition to the fiber type, you'll also want to pay attention to the shell's weave and thread count, just like you would with other bedding. Thread count refers to the number of horizontal and vertical strands that can fit into one square inch of fabric, so a higher thread count can mean a smoother and denser surface. A material’s weave refers to the style in which the fabric is constructed, and some popular styles include sateen, percale, and plain. While thread count and weave matter less if you're using a duvet cover, a smooth and airy fabric may still promote temperature regulation even with a cover. In terms of a comforter with a luxuriously soft shell, we recommend the PrimaLoft Alberta Comforter, as the softest pick on our list.

Fill Material

Down-alternative comforters are a great option for people with allergies, as goose and duck feathers can irritate some people. It's important to recognize the signs of an allergic reaction, so you know if your bedding isn't right for you.

"Often a suspected feather allergy is actually an allergy to dust mites, whose proliferation is encouraged on and around feathers," says Heather Viola, DO, Department of Medicine, Division of General Internal Medicine. Down-alternative comforters avoid this risk, while still maintaining all of the lightweight yet cozy properties of traditional down.

So, what are down-alternative comforters filled with instead? Ultra-fine polyester fibers are the most common replacement for feathers. Though this is a synthetic substance, it's often sourced from recycled materials, such as plastic water bottles. You'll also find some comforters filled with high-quality natural materials like viscose (bamboo), such as our top luxury pick, the Cozy Earth comforter, or silk. Just keep in mind while silk may be allergy-friendly, it isn't vegan.

Loft

Loft refers to the fluffiness of the comforter. While it can be hard to gauge the specific loft of each down-alternative comforter, note that baffle box constructions tend to offer more loft than their sewn-in counterparts. The amount of loft that's right for you is mostly up to personal preference, but when you think of a lofty comforter, imagine an airy and cloud-like construction that offers significant height. One of our loftiest options is the Buffy Cloud Comforter.

FAQ
  • Who should purchase a down-alternative comforter?

    If you enjoy the comfort of traditional down comforters, you can't go wrong with a down-alternative option, as they're exceptionally similar with a few added benefits. Without sacrificing quality and texture, down-alternative comforters usually have a lower price point, hypoallergenic qualities, easier care instructions, and use recycled materials.

    Both down and down-alternative comforters can be suitable for all-season use, as they're lofty, insulating, and breathable. Contrary to popular belief, down-alternative filling can be just as warm and insulating as traditional down, depending on the quality of the material, fill level, and shell thickness.

  • How do you care for a down-alternative comforter?

    The proper way to wash a down-alternative comforter really depends on the material, stitching, and overall construction. Generally speaking, you should be able to launder yours in a standard washing machine on a delicate cycle (or bulky, depending on the loft) with cold or warm water. Most duvet inserts can also be tumble-dried on low heat, though some call for air-drying. Some brands suggest spot-cleaning or dry-cleaning only, so be sure to check the instructions before cleaning yours.

    Finding a comforter that holds up well after multiple washes is crucial, according to Kenneth Mendez, president, and CEO of the Asthma and Allergy Foundation of America. "Because frequent washing is recommended for people with asthma and allergies, the bedding product should not break down even after multiple wash cycles so that the allergen barrier function still works," he says.

    Additionally, you may find that your comforter needs regular fluffing in order to maintain its loft and ensure that the fill stays even throughout. Simply give it a good shake before making the bed every now and then to help the comforter keep its shape and avoid clumping.

  • When does a down-alternative comforter need replacing?

    Most down-alternative comforters last for three to five years, though it depends on the material, usage, and overall quality. If yours is lumpy, flatter than it once was, or permanently stained, or has a funky odor, it might be time to swap it out for a new one.
