There's nothing like a duvet day in the depths of winter. When you sleep with the best warm comforter, you can cuddle up without worrying about lumps, bumps, or cold patches. A quality comforter will be breathable, too, wicking away moisture to keep you just the right side of warm and dry.

There are down duvets, filled with real duck and goose feathers, as well as down alternative comforters to suit sensitive sleepers and vegan shoppers. Premium duvets tend to come with a premium price tag, though some of the best warm comforters come in well under budget. There are so many kinds of comforter, sold at so many specialist sleep stores, that it can be difficult to know where to start. 

That's where I come in. As H&G's resident sleep writer, I lead a team of expert testers. Together, we've slept under some of the best duvet inserts money can buy. We've already crowned the best cooling comforter for hot sleepers. Now, it's time to find an ultra-warm insert to suit cold sleepers and cooler climes.

Our experts test comforters for months, if not years, to monitor their performance over time. When we haven't been able to get our hands on a duvet, we've scoured the specifications and read countless customer reviews to ensure we're recommending quality comforters. We've assessed each piece on the basis of comfort, warming properties, ease of cleaning, and the all-important price.

We'll dive into the details further down. If you just want to get shopping already, here are the best warm comforters at a glance.

The best warm comforter overall

1. Boll & Branch Ultraweight Down Duvet Insert

The best warm comforter overall

Specifications

Fill type: RDS Down
Material: Cotton, down
Sizes: Full/Queen, King/Cal King

Reasons to buy

+
Ethically sourced down
+
Soft to the touch
+
Bafflebox construction to maintain loft

Reasons to avoid

-
Not suitable for twin-sized beds
Buy it if:

✅ You like a lot of loft: Boll & Branch construct their comforters using bafflebox stitching for the even distribution of down.
✅ You like to shop sustainably: all the down in this comforter is ethically sourced and certified cruelty-free.
You have sensitive skin: this comforter is wrapped in an organic cotton shell, which is soft to the touch and soothing on your skin.

Don't buy it if:

❌ You have a twin-sized bed: this comforter only comes in sizes Full through California King.
❌ You don't have a dryer: this duvet insert is stuffed so full that it takes two or three cycles to fully dry.
You're on a budget: like a lot of Boll & Branch bedding, this comforter is seriously expensive.

The bottom line

🔎 Boll & Branch Ultraweight Down Duvet Insert is seriously expensive, but you get what you pay for. The bafflebox stitching keeps the fill perfectly in place for evenly distributed loft. This comforter looks good and should keep you cozy in colder weather. 

The Boll & Branch Down Duvet Insert is the best duvet insert, bar none. This comforter comes in three weights to support each sleeper's ideal temperature. There's a lightweight layer for hot sleepers and warmer climates, as well as a midweight option for year-round use. If you tend to sleep cool, or you live in a colder climate, your best bet is the Ultraweight Duvet Insert, which comes with a thicker feather fill.

Boll & Branch incorporates bafflebox stitching into each insert to hold the feather fill in place. No lumps, bumps, or cold patches: just cozy comfort, all through the night.

This comforter is filled with real duck and goose feathers, ethically sourced from American farms to meet the Responsible Down Standard. That means that each stage of production, from farm to factory, is investigated by an independent organization to uphold the highest standards of comforter quality and animal welfare. 

This duvet insert looks good and sleeps warm, but it's a little tricky to clean. While this comforter is technically machine-washable and dryer-safe, it takes two or three cycles to dry completely, costing you time and money in energy bills.

The best warm down comforter

2. Brooklinen Ultra-Warm Down Comforter

The best warm down comforter

Specifications

Fill type: Down
Material: Down, cotton
Sizes: Twin/Twin XL, Full/Queen, King/California King

Reasons to buy

+
Antimicrobial
+
Hypoallergenic
+
Soft-to-the-touch sateen shell

Reasons to avoid

-
Spot-cleaning recommended
Buy it if:

✅ You have a twin-sized bed: unlike a lot of comforters, this duvet insert comes in every size from Twin through to California King.
✅ You have sensitive skin: unusually for down products, this comforter is totally hypoallergenic.
✅ You like your comforter super soft: Brooklinen use down clusters rather than individual feathers for plush comfort.

Don't buy it if:

❌ You're shopping for something easy to clean: you shouldn't machine-wash this comforter, only dry clean.
❌ You only want to purchase vegan products: this comforter is filled with real duck and goose feathers.
❌ You're on a budget: this duvet insert is seriously expensive.

The bottom line

🔎 Brooklinen Ultra-Warm Down Comforter is suitable for sensitive sleepers and eco-conscious shoppers alike. If you're only interested in purchasing vegan products, you might want to shop elsewhere.

A lot of down duvets are filled with individual feathers. These feathers hold heat and keep you cozy, but their stalks can break through the cover of your comforter to scrape and scratch your skin. That's why Brooklinen fill their duvets with down clusters, which feel lighter and softer than feathers, while delivering the same level of warmth.  

The Brooklinen Down Comforter comes in three weights: lightweight, all-season, and ultra-warm. If you live in a cooler climate, or you like to cuddle up in the colder months, you might appreciate the ultra-warm option. This comforter comes in every size from Twin to California King. Perhaps it goes without saying, but it bears repeating that the larger and thicker the comforter, the more expensive it is.

Unusually for a down duvet, this comforter is hypoallergenic and suitable for sensitive sleepers. It's treated with ultra-fresh antimicrobials, which work to kill the bacteria that breed in hot, damp environments, such as bedrooms. The Ultra-Warm Comforter should keep you just the right side of warm and dry, while combatting microbes, mold, and mites. 

However, like a lot of down products, this duvet insert doesn't wash well. Brooklinen recommend spot cleaning smaller spills and stains and dry cleaning when necessary: you shouldn't run this comforter through the washing machine. Since you only need to wash your duvet insert once a season, this isn't a dealbreaker, but it is irritating.

The best warm down alternative comforter

3. Saatva Heavyweight Down Alternative Comforter

The best warm down alternative comforter

Specifications

Fill type: Down alternative
Material: Lyocell and percale cotton
Sizes: Twin/Twin XL, Full/Queen, King/California King

Reasons to buy

+
Hypoallergenic
+
Moisture-wicking
+
Machine-washable

Reasons to avoid

-
On the more expensive side
Buy it if:

✅ You want to purchase vegan products: no feathers here, only down alternative and lyocell fill.
✅ You tend to sweat while you sleep: lyocell is naturally moisture-wicking to cool you down and keep you dry.
✅ You're shopping for something easy to clean: just wash in cold water and tumble dry on low.

Don't buy it if:

❌ You like the feel of feathers: this down alternative duvet insert lacks the loft of real down.
❌ You live in a temperate climate: this warm comforter might be too cozy for year-round use.
❌ You want a colorful comforter: this piece only comes in white, though it features corner loops to attach inside a duvet cover.

The bottom line

🔎 Saatva Heavyweight Down Alternative Comforter offers the same plush comfort as a standard Saatva duvet, with a thicker fill to keep you warmer in winter. The only downside is that this duvet insert lacks the loft of real down.

Many of the best warm comforters are filled with real down, which holds heat and air to create natural loft and cozy comfort. However, there's one big downside to down duvets. Since they're stuffed with duck and goose feathers, down comforters cannot be classed as vegan. If you're keen to avoid animal products of all kinds, you might sleep more comfortably with a down alternative duvet. 

Enter the Saatva Heavyweight Down Alternative Comforter. This ultra-warm insert offers the same plush comfort of the standard Saatva duvet with thicker layers to keep you cozy. The comforter is filled with a unique blend of down alternative and breathable lyocell, which is naturally moisture-wicking and thermoregulating to keep you just the right side of warm and dry. 

Down alternative duvets tend to be easier to wash and dry, and the Saatva Heavyweight is no exception. All you need to do is throw it in the washing machine on a cold cycle and tumble dry on low. Give it a good shake as you take it out of the dryer and it should look as good as new. 

The Saatva Heavyweight Comforter retails for around $345 in the queen size. While that might sound like a lot of money to drop on a duvet, this is one of the more affordable warm comforters on the market. If you live in a consistently cooler climate, or you like to cuddle up in the winter months, you'll get a lot of use out of this cozy comforter.

On the more expensive side
Buy it if:

✅ You like to shop sustainably: this duvet insert uses only organic, natural, and renewable materials.
✅ You tend to sweat while you sleep: alpaca fiber is naturally moisture-wicking.
✅ You're a clean freak: since alpaca fiber is naturally antimicrobial, it should kill bacteria, mold and dust mites.

Don't buy it if:

❌ You live in a really cold climate: this duvet insert only comes in lightweight and all-season warmth levels.
❌ You have a Twin XL bed: that's the one size missing from the Avocado range.
❌ You like the feel of feathers: this alpaca duvet insert is closer to wool in terms of texture.

The bottom line

🔎 Avocado Alpaca Duvet Insert is naturally moisture-wicking and anti-microbial. It should keep you just the right side of warm and dry while busting the bacteria that breed in hot, damp environments, such as bedrooms. 

When you're looking for the best warm comforter, it pays to shop around. Your options extend beyond down and down alternative to encompass breathable bamboo, smooth silk, and even sheepskin. For eco-conscious shoppers who tend to sweat while they sleep, I recommend alpaca. 

This duvet insert is filled with alpaca wool, which is hand-shorn and sustainably sourced. Moisture-wicking and thermoregulating, antimicrobial and hypoallergenic, alpaca wool checks all the boxes that make up good bedding. The insert is wrapped in an organic cotton percale shell to boost breathability. 

The Alpaca Duvet insert comes in two weights: lightweight for warmer climates, and all-season for year-round use. In the absence of a designated heavyweight or ultra-warm option, I'd recommend sleeping under the all-season to stay warm and dry. 

While the Alpaca Duvet Insert is neither machine-washable nor dryer-safe, it's relatively easy to clean. Avocado recommend spot cleaning to counter smaller spills and stains and hanging the comforter in direct sunlight to restore freshness. If you want to resist wear and tear, you could cover the Alpaca Duvet Insert with a cotton or linen slip.
