Ideal for year-round use, this cloud-like duvet insert (which comes with a silky Egyptian cotton shell) boasts eight corner loops to keep your cover in place, as well as a baffle-box construction to keep the down fill evenly distributed. And though dry cleaning is recommended, reviewers say it holds up fine in the wash.

THE REVIEW: “Wow! Amazing quality, especially for the price point,” reads one review. “The warmth is so even. As soon as I opened it, I threw it around to fluff, then put it in the dryer on air dry. A few more fluffs from me, and I put it on my bed. The squares are completely full. 100 percent happy with my purchase.”

Yes, down comforters can be a liiiiittle pricey, but this one is def worth the splurge (especially if you’re already obsessed with Brooklinen’s dreamy sheet sets). Sustainably sourced and made with a silky 100 percent cotton sateen shell, this fluffy down cluster-filled duvet comes in three different weight options—though the all-season is best for year-round comfort.

• Shell material: Cotton sateen
• Fill material: Down
• Sizes available: Twin/twin XL, full/queen, king/Cal king
• Warmth levels: Lightweight, all-season, or ultra-warm
• Care instructions: Spot clean recommended; dry clean if needed

THE REVIEW: As one tester writes, “Living in Florida, it is difficult to find a comforter that is light, comfortable, and airy. I have had multiple duvet covers/insert and comforters, and my Brooklinen Down Comforter has been by FAR the best. I cannot recommend product and brand more!!”

This fluffy yet breathable down alternative comforter has earned nearly 30,000 five-star reviews on Amazon for a reason: It’s ah-mazing quality for the price. Though it’s not the loftiest option, you’ll love the leak-proof box-stitch design, the lightweight feel, the corner tabs, and the fact that it comes in 10 colorways—all for less than $70.

• Fill material: Polyfill
• Sizes available: Twin, twin XL, full, queen, oversized queen, king, oversized king, Cal king
• Warmth level: All-season

THE REVIEW: “This comforter is extremely well made,” one buyer notes. “I was using a thinner down comforter and needed another one. It’s not too thin or thick and is super comfortable. The fabric is very smooth and breathable. I typically sweat in my sleep but haven’t so far with this comforter. Really happy with it and highly recommend!”

FYI, I’ve been sleeping under this bad boy for six months now, and it delivers Every! Single! Night! It’s filled with 100% GRS-certified recycled PET fill (a v convincing hypoallergenic down alternative, so no feather bits sticking out) and it’s so f’ing comfy. I usually have to use a second blanket under my duvet during the winter, but the Buffy Cloud Comforter has gotten me through the worst of the cold on its own! It has a good amount of fluff and a very slight weight to it, which I find to be super soothing when you’re lying underneath. Oh, and this option even has thoughtful loops for easily attaching a duvet cover, so laundry day will no longer be the bane of your existence!

THE REVIEW: “We love this comforter,” one reviewer writes. “It’s both lightweight and warm. We like to sleep in a cold room and both experience temp fluctuations throughout the night. Other blankets had us flipping them on and off again to stay comfortable. This blanket is just right all night long.”

If your goal is fluff to the max, this is the duvet insert for you. I’d even recommend double-stuffing to really get that oversized, plush look. Don’t panic if it looks flat right out of the box—customers recommend tossing the duvet in the dryer on low heat for 10 minutes after you take it out of the vacuum-sealed packaging to achieve that extra cloud-like feel!

THE REVIEW: “Oh my god this is the best down comforter I’ve ever slept with. Once you have this on your bed, you are going to sleep so much better I can guarantee you that,” one reviewer writes. “Not only is it the perfect warmth, but it just wraps around your body so nicely, and has a little weight to it but not too much. My husband has problems sleeping and we both move around a lot with this comforter, both of us stay put all night and wake up the exact same way that we fell asleep. Crazy! Highly recommend it. in fact, get more, one for every room.”

Want the coziest sleep of your life for $25? Presenting a surprisingly affordable down comforter option: this v good find from Amazon.

THE REVIEW: “This duvet insert is exactly what we needed. It’s fluffy and lightweight, warm but not too warm. The 8 loops make it secure inside the cover and keep it in place perfectly,” one customer wrote. “I laid it out flat for a few hours, since it comes vacuum sealed and needs time to fluff up, but I got impatient and just stuck it in the dryer on low for a bit. I swear it came out of the dryer doubled in size. It’s perfect. Absolutely no complaints.”

Hot summer nights, freezing air conditioning, blasting heat, drafty windows—yikes. Instead of accumulating four different blankets for each season, why not invest in a single duvet to rule them all? This is SlumberCloud’s lightest option, ideal for literally every season (yes, including summer!) thanks to the NASA-engineered technology that keeps you in the “just right” zone all night. The duvet will absorb excess heat to prevent you from overheating, and if your temperature begins to drop, that stored heat will be released back into your skin. Nifty, huh?

• Fill material: Hypoallergenic ClimaDry™ by Outlast fiberfill
• Sizes available: Twin XL/twin, queen/full, king/Cal king
• Warmth levels: All-season
• Care instructions: Machine wash

THE REVIEW: “I first slept under this type of comforter when traveling and fell in love with it being somewhere between a blanket and a comforter,” one reviewer wrote. “Not bulky like a full-on comforter can be, but cozier than just a blanket. My husband and I are loving this product! Just what I was looking for and now he is sold on it as well!”

If you’re in a ~thermally-incompatible~ relationship (basically, the bed is never the right temp for both of you), this temperature-regulating duvet might just change the game. The bamboo viscose fabric will wick away moisture, regulate heat, and somehow keep you warm without ever feeling overly heavy as you dream. Plus, it’s just so dang luxe—one shopper wrote that this comforter feels “like money.”

• Sizes available: Twin, queen/full, king
• Warmth levels: All-season
• Care instructions: Spot clean or dry clean, hang dry in mild to moderate sunlight once every 3-5 months for 1-3 hours—the brand says that regular or excessive washing of our comforters is unnecessary if you are using and washing your protective duvet cover

THE REVIEW: “These comforters—this is my second one—are just plain old perfect! Abundant softness, luxurious feel and, I’m not sure how they do it, but they are light, drape over your body – and are always the right level of warmth,” one customer wrote. “I get too hot under a down comforter. The bamboo comforters feel warm within minutes, but never are too hot. Did I mention washable? The best.”

Good news—just because you sleep hot doesn’t mean you’re sentenced to thin, flat blankets forever. Customers describe this hiiiighly breathable option that rings up at a mean $26.99 and weighs less than three pounds (!) as “surprisingly great,” “not too hot,” and “insanely perfect.” It’ll gently contour to your body without feeling too warm and even has box stitching to prevent filling from shifting around in the insert.

Highly recommend!!”

Anyone who’s willing to shell out big bucks for a new duvet should feast their eyes on this suuuuper-luxe option from Boll & Branch, which boasts an organic cotton shell and unique bafflebox construction for an incredibly lofty lewk.

Alright, so you’ve got a couple different options, and it really boils down to your personal preference:

Traditional, regular down filling typically consists of lightweight goose or duck plumage and feathers—it retains heat well, making it ideal for cold sleepers and winter months, and tends to be on the more expensive side.

For the more budget-conscious (or vegan!), alternative down is usually made of synthetic materials like polyester. It’s a hypoallergenic option that shouldn’t trigger dust or dander allergies the same way regular down might.

For those who are looking for more natural fill options, look for a duvet insert made with bamboo, eucalyptus, wool, or even silk, if you’re feeling splurge-y. Natural fibers tend to be more on the breathable side, so you’ll get the super plush effect of a duvet insert or two without overheating in the middle of the night!

Selecting a duvet insert is one of those things that is completely left up to personal preferences, but when shopping for the right duvet, here are some things to look for:

Find the right weight

Duvets are notoriously known for being pretty warm—which isn’t exactly great for hot sleepers. But the good news is there are different duvet weight options to choose from, so if you tend to have sweaty snoozes but still want that fluffy duvet experience, then you can (literally) rest assured that there’s a lightweight or cooling duvet for you. Typically, you can find duvet inserts available in these weight levels: lightweight, heavyweight, or all-season.

Lightweight options are great for warmer months and hot sleepers, while heavy duvets are fantastic for colder months and cool sleepers. And all-season duvets are exactly what they sound like—duvet blankets that are suitable for year-round use, thanks to their temperature-regulating fill. If you want to get really fancy with it, some companies offer two or three different weight options to really help you customize your sleep experience.

Consider the care instructions

Since duvet inserts are meant to be put inside a duvet cover, they typically only need to get washed every four to six months. However! Spills can and do happen, and getting your duvet professionally laundered can be expensive (not to mention a pain). If you have pets or kids (or just happen to be v spill-prone), consider skipping the spot-clean-only or dry-clean-only duvets for something you can easily toss in the wash at home.
