Best Duvet Inserts 2024 – Forbes Vetted

The best duvet inserts make perfect companions for your favorite duvet covers. Together, they add just the right amount of fluff, warmth and breathability to your sleep setup. Based on hours of research and after reading through countless reviews, we awarded Sleep Number’s Create Your Own Comforter the title of best duvet insert overall. The affordable price tag was definitely a plus, but its customizability won us over. Couples can customize each half of the comforter to satisfy their individual comfort preferences and sleep styles—a win-win for both partners. But if you’re looking for something else, say an all-season duvet insert like the Brooklinen Down Alternative Comforter, we have you covered, too.

While aesthetics is a top consideration when shopping for duvet covers, when it comes to looking for a duvet insert, the focus should be on effectiveness. To select the right duvet insert, consider the size of your mattress, what kind of duvet cover you have, your sleeping style, the temperature changes in your living space, your preferred fill material and your budget. After that, it’s simply a matter of picking one that speaks to your personal comfort preferences. With that in mind, see our list of the best duvet inserts below.

It’s rare to find a quality duvet insert for under $100, but Linenspa offers one that’s under $50—and it’s incredibly popular to boot. Reviewers on Amazon praise its fluffiness and budget-friendly price tag. Stuffed with a plush down alternative for all-season coverage, the insert has corner and side loops to help keep everything in place. A quilted, box-stitch design secures your fill, so you don’t have to stress about things shifting around over time. Choose from a range of sizes, including “oversized” king and queen options, just in case you prefer a larger coverage area.

Some people are happy to swap out their comforter as the seasons change or add and subtract blankets as the need strikes. Others simply can’t be bothered. If you fall into the latter camp, select an all-season duvet insert like Brooklinen’s down alternative option to keep you cool on hotter days and warm when temperatures drop. This comforter keeps you at an even temperature year-round and has a baffle box construction to prevent your fill from shifting around. Loops on every corner make it easy to attach to your duvet cover—and keep it in place, too. Since it’s made from recycled PET fibers repurposed from plastic bottles, you can also feel good knowing you’ve helped the environment with this purchase.

Pottery Barn’s Hydrocool duvet insert has plenty of features that help it make your sleep experience as comfortable as possible. The down alternative insert is filled with the company’s proprietary Hydrocool performance polyester, which is specially designed to pull moisture away from you while you sleep to create a cool, dry environment. Box quilting keeps the fill from shifting, while corner loops keep your duvet cover in the right spot. Choose between mid-weight and ultra-plush options, with the latter creating a fuller, more fluffy feel in bed.

Finding the right comforter as a hot sleeper can be tricky: You want to be warm enough to feel cozy, but not so hot that you end up sweating in your sleep. The Buffy Breeze is specially designed to regulate your temperature. It features Tencel fabric to absorb moisture more efficiently than cotton and has an overall airy weight, so you don’t feel weighed down while you sleep. The insert features loops on every corner to secure your duvet in place. It’s even fully biodegradable and compostable for when you decide to trade it in for a newer version. (Just note: It’s recommended that you dry clean this insert as a result.)

  • Sizing is a bit oversized

Down is a traditional duvet insert fill, and for good reason: It creates a fluffiness that’s hard to match. This particular comforter is stuffed with ethically sourced, hypoallergenic down and feathers for a lofty feel. Box stitching keeps all that fluffiness in place, and you can choose from four different warmth levels: Light, Medium Warmth, Extra Warmth and Ultra Warmth. There’s even a massive range of color options, just in case you want to have the option of bypassing a duvet cover.

Made of 100% organic cotton, the shell is soft, breathable and reminiscent of a hotel-quality comforter. It features a baffle box design that keeps the down in place, and is filled with down interior that’s certified by the International Down Standard, which means it’s ethically sourced from local farms. We also like that it’s available in three weights (light, medium and ultra), so there’s an option for nearly any sleeper.

What To Look For In A Duvet Insert

A duvet insert is an important bedding element to ensure you stay comfortable and warm while you sleep. Consider these factors as you shop.


There are a few options for fill, which is the material inside your duvet insert. “It’s a bit like a ‘choose your own adventure’ based on your sleep preference,” says head of interior design for Pacaso Lauren Farrell. “From down to down alternative or synthetic fill, there are several weight options.” Each feels slightly different, too. “Down is like a warm, fluffy cloud—perfect for colder climate destinations, but comes with a higher price,” Farrell says. However, if you’re “more cost-conscious or perhaps have allergies, the alternatives are the way to go.” Some vegans who want to avoid purchasing items made with animal products also prefer down alternatives.


Duvet inserts usually come in a variety of weights, including light, medium, heavy and an all-season variety, which is made to be comfortable year-round. In general, the ideal temperature for sleep is 65 to 67 degrees, sleep medicine physician W. Christopher Winter says. However, he points out that the fill of your duvet is individual. “Layers are what I suggest, so you can add and subtract,” he says. Heavyweight duvet inserts are insulating and ideal for cold winter months, while lightweight inserts are better for warmer climates.


Fabric selection is “crucial,” Farrell says. “You’ll want something soft and that washes well,” she says. Popular options include sateen cotton, percale and microfiber. “I personally love sateen cotton, which is super-soft to the touch because of its flat weave, whereas percale has a more open weave,” Farrell says. “Percale is ideal for coastal locations and anyone who sleeps hot. But, for me, sateen is the winner just because of how slippery soft it is.” Cotton is also hypoallergenic, which Farrell calls a “functional choice” for dressing up beds and keeping them cozy.


A duvet insert’s construction helps ensure your bedding stays fluffy, so you don’t end up with flat spots. That means looking at the construction of the duvet insert, including the stitching and how well the fill is secured within the cover, Farrell says. (Box stitching is a common technique, although it’s not used in every duvet.) “What’s great about duvets as opposed to comforters is that they are easy to toss in the wash,” Farrell says. “However, with frequent laundry trips, it’s important to consider the construction, so that it doesn’t fall apart after just one wash,” she says. Reading the reviews on a duvet insert you’re considering can help give you an idea of how well a duvet insert holds up over time.

Duvet Vs. Comforter

Duvet inserts like the ones on this list are designed to be paired with a duvet cover. If you want a blanket with a cover that’s not made to be removed, you may be in the market for one of the best comforters.
