When it comes down to it, the fluffiest duvet inserts are what make the bed. Yes, you want something warm and cozy when the temperatures drop, but even when you’re not freezing your tush, extra-soft and breathable bedding is a recipe for a good night’s sleep in anyone’s bedroom. “A fluffy, high-loft duvet delivers the most consistent sleep experience across seasons,” says Anthony Loiacono, director of rooms at L’Auberge de Sedona, a wellness resort in Sedona, Arizona. “It provides warmth without weight, and most importantly, adapts to day-to-night temperature shifts.” When your bedding has that added fluff factor, the entire experience changes. A pouf of a comforter can be like a balm during the winter months.

When it comes to selecting the best fluffy duvet insert for you, consider the following: Pay attention to fill distribution—that’s where the baffle-box construction plays a huge role. A durable, high-quality shell that maintains its feel over time is also of utmost importance. “These details may seem small, but they play a meaningful role in how rested and restored a guest feels come morning,” Loiacono adds.

In terms of fill, down reigns supreme, especially in the luxury hospitality business. It delivers reliable warmth and softness while remaining lightweight and breathable, Loiacono explains. However, if you have allergies, a high-quality down alternative is worth exploring, especially a design made out of lyocell that’s sustainable and cool to the touch (and perfect if you run warm).

To test the fluffiest bedding, we had AD editors and contributors try out everything from heritage down comforters to hypoallergenic down-alternative duvet inserts. We slept in this bedding during frigid Midwestern winters to milder West Coast nights that are suited for warmer climates. That’s why this list includes both heavy, high fill powers and light inserts that will please even the hottest sleepers.

Boll & Branch is an AD-favorite bedding brand, and that’s why the down duvet insert is high on our list. It comes in three weights—light, mid, and ultra—so you can tailor it to your ideal climate. “The baffle-box construction keeps the down evenly distributed throughout the cover,” says AD PRO senior editor Mel Studach in her review of the best duvet inserts. Its organic cotton shell is not only breathable, but won’t let the fills poke through as you fall into deep slumber. You’ll also sleep soundly knowing that the brand is known for upholding Fair Trade and Global Organic Textile Standards (GOTS), which certifies you’re sleeping under something that isn’t packed with icky microplastics.

Best All-Season Duvet Insert

Let’s be honest, sometimes the best staycation is the one that involves your bed. Case in point: Contributor Rebecca Grambone considers the Brooklinen down comforter “very high quality and luxurious,” with “strong hotel bed vibes.” It comes in three varieties: lightweight (650 fill power), all-season (700 fill power), and heavyweight (750 fill power). When paired with an airy percale duvet cover and sheets, the combo further elevates the experience to a five star-inspired retreat.

Best Affordable Option

AD editors love Quince bedding, and this goose down comforter is just another piece we recommend. Contributor Zoë Sessums points out that, while affordable, the baffle-box construction and double-stitched seams emphasize the high-quality design. The fluffiness of this down duvet insert is far from lumpy. Now may be the time to order the ultra weight, but as you escape the winter, all-season and lightweight options are always suitable for anyone who sleeps hot.

Best Cloudlike Option

The japara cotton, woven with medium to fine yarns, gives the Ostermoor down duvet a true cloudlike finish that quite literally inflates upon unboxing. The full size even shocked contributor Yelena Moroz Alpert, who initially thought the petite packaging suited a set of sheets. “The packaging was vacuum sealed but once I opened it up, it started to fill up with air. Sure, it was a bit wrinkly at first, but like an air balloon, it just kept inflating and soon I saw marshmallow-like pockets come to life,” she says. “When I sleep on it, it truly feels like someone placed cotton candy inside the duvet, that’s how light it is. If I try to squeeze one of the pockets, it shrinks and then automatically fills right back up. Originally, I was worried that it might feel too heavy, but it is the lightest duvet insert I have, yet it is also the warmest.”

Best Down Alternative

Saatva All-Year Down Alternative Comforter

$315

Saatva

Saatva’s claim to fame may be their reputation for some of the best mattresses we’ve tried, but the brand’s bedding is worth paying attention to as well. Global content strategy and operations director Diane Dragan is a fan of the touch, the feel, and the quality. “There are certain items you buy once as an investment and keep forever—this feels like one of them,” she says. The choice is noteworthy for anyone who is sensitive to down and is available in three comforter weights: lightweight (220 GSM), all-year (340 GSM), and heavyweight 420 GSM. One look at this box quilted design and you’ll be tempted to crawl into bed.

Best Luxury Pick

Cozy Earth Silk Comforter

$578 $491 (15% off)

Cozy Earth

When market director Madeline O’Malley needed to upgrade her bed, she relied on Cozy Earth. “I totally trust the brand,” she says, noting that the company’s story focuses on temperature regulation. She chose the silk filling because it is “fluffier and more robust.” Though you can also go for the bamboo viscose or down alternative fill options, if those are more your jam. “It’s impossible to imagine being too hot right now,” she adds. “But I feel I'll continue to use my duvet in the warmer months—for the fluff.” She was also pleased to find that the shell feels silky and soft. “Even though I use a Matouk duvet cover so nobody will ever see the insert, I like knowing that it’s nice looking,” she jokes.

Best for Hot Sleepers

It’s all right here in the name. The Buffy Cloud comforter is a breezy bestseller that appeals to everyone, but especially if you’re into feeling cocooned. Shopping director Rachel Fletcher loves its look and weight. “The fibers are naturally a little heavier, which makes it more substantial and warmer than other cooling comforters I’ve tried [like the Casper], but it’s not as overwhelming as a traditional down comforter,” she says in her review. Like the original Buffy comforter, it has loops in every corner, so it can be used interchangeably as a comforter or duvet insert. Hot sleepers will be glad to know that the smooth sateen weave lyocell shell is more absorbent than regular cotton.

Best for Winter

IKEA FJÄLLHAVRE Duvet Insert

$249

Ikea

The Fjällhavre duvet insert, like much of IKEA, is no frills. Yet, this down-and-feather piece can hang with the rest of the best on our list. The piping on the side walls gives the comforter added fluff factor, but still keeps the structure in place. This fluffy duvet insert is made for anyone who wants to be nestled but not veer into princess bedding territory.
