A quality comforter is a sleep essential. The best comforters are filled with lots of little air pockets to retain heat and enhance breathability. Since they come without a cover, they're wrapped in soft and stylish shells. A duvet is a lot like a comforter, only it's made up of two parts: the insert and the cover. 

Hot sleepers will appreciate a lighter layer, while a heavy-duty comforter might be more suitable for cooler climates. Down comforters are filled with real feathers, which trap heat to keep you warm in the winter, though vegans or allergy-suffers might prefer a down alternative option. In short, there are so many sorts of comforters that it can be difficult to find one that suits your sleep needs. 

That's where we come in. Our expert sleep editors know all the best places to buy comforters. After trying all the best duvet inserts, we've narrowed it down to our top nine to suit every season and sleep style. 

We've tested each of these comforters for months, if not years, to monitor their performance over time. We've ranked them based on comfort, sustainability, and ease of cleaning, as well as the all-important price.

Sizes: Full/Queen, King/Cal King

Reasons to buy

Not suitable for twin-sized beds
Buy it if:

You have sensitive skin: this duvet insert is hypoallergenic, so it soothes your skin while you sleep.
You're looking for an animal-friendly insert: the fill in this duvet meets the Responsible Down Standard. That means each stage of production meets the highest standards of quality and animal welfare.
You're a cool sleeper: this duvet insert comes in three levels of warmth, so you can pick the thickness that suits you.  

Don't buy it if:

You have a twin bed: this duvet insert only comes in Full, Queen, King, and California King sizes.
You don't have a dryer: this duvet insert is stuffed with so much fill that it takes two or three cycles to fully dry. You couldn't air dry it.
You're a warm sleeper: even the lightest layer is pretty weighty, according to customer reviews. 

The bottom line

🔎 Boll & Branch Down Duvet Insert is a great option for eco-conscious sleepers who don't want to compromise on comfort. 

The Boll & Branch Down Duvet Insert offers something for everyone, whether you sleep hot or cold in a full bed or a California King. 

This duvet insert comes in three thicknesses. The lightweight option is more comfortable in warmer climates, while the ultra-weight insert provides superior cozy comfort. 

Each insert is filled with real down, sourced from American farms, that meets the Responsible Down Standard. That means each stage of production, from farm to factory, is investigated by an independent organization to ensure the highest standards of quality and animal welfare. 

This down is also washed with eco-friendly, Bluesign-certified detergent, which makes it two times cleaner than the federal standard.

While the Down Duvet Insert is definitely on the more expensive side, it's a worthwhile investment for eco-conscious sleepers. Just remember that there's no twin size for single beds.

On the more expensive side
Buy it if:

You live in a temperate climate: this comforter is made from plush down alternative and breathable lyocell. It keeps you warm in the winter and cool in the summer.
You tend to sweat as you sleep: lyocell is naturally moisture-wicking and odor-repellent, so this comforter should keep you cool and dry.
You want a comforter you can clean easily: this piece is machine-washable and dryer-safe on gentle cycles.  

Don't buy it if:

You live in a warmer climate: you might be better off with a lighter layer, such as Saatva's Lightweight Down Alternative Comforter.
You want a colorful comforter: this piece only comes in white, though it comes with corner loops to attach inside a duvet cover.
❌ You're on a budget: this comforter is on the more expensive side. 

The bottom line

🔎 Saatva All-Year Down Alternative Comforter is plush and breathable. It's perfect for sleepers who want to stay cool but won't compromise on comfort. 

This comforter is filled with a unique blend of plush down alternative and porous lyocell fill. It's thermoregulating, conducting heat away from your body as you warm up and releasing it once you start to cool down. 

Saatva's All-Year Comforter strikes the perfect balance between warmth and breathability. That means it's suitable for hot and cold sleepers in warm or cool climates. 

When our expert tested it in the middle of June, she found it to be much cooler and more comfortable than her regular down blanket. With that said, this comforter might be too cozy for a heatwave, especially in houses without AC. 

As comforters go, this one is easy to clean. All you need to do is throw it in the washing machine on a cold cycle and tumble dry on low. You might want to wash it alone − the queen-size comforter took up almost the entire drum of my front-load washer. Fluff between spins for best results. 

This down alternative comforter is hypoallergenic, vegan-friendly, and feels like the real thing.

Spot-cleaning recommended
Buy it if:

You're a sensitive sleeper: unusually for down, this comforter is totally hypoallergenic.
You tend to sleep hot: you'll appreciate the cooling properties of the cotton sateen shell.
You have a twin bed: unlike a lot of comforters on this list, this piece comes in every size from Twin to California King.

Don't buy it if:

You're looking for something machine-washable: this comforter needs to be spot-cleaned.
You're vegan: this comforter is filled with real duck and goose feathers. You might be more comfortable with a down alternative comforter.
You're looking for a colorful comforter: this piece only comes in white, though it should blend beautifully with any bedroom color palette.

The bottom line

🔎 Brooklinen Down Comforter is a little high-maintenance, but it's hypoallergenic and cool to the touch.

Where most down comforters are filled with individual feathers, which can poke through the surface to scratch your skin, this comforter is stuffed with clusters for a softer feel. 

Since these are real feathers, rather than synthetic, this Down Comforter may not be suitable for vegans. It's worth saying, though, that Brooklinen source their down from Canadian flocks using sustainable farming practices. As down comforters go, this one is pretty eco-friendly.

With a lightweight, mid-weight, and ultra-warm option, there's a Down Comforter to suit every season. As a general rule, it sleeps cool. Our sleep editor tested the mid-weight design in the middle of a Georgia heatwave, and still felt it was light and airy. 

Each comforter is wrapped in a cotton-sateen shell that's soft on your skin and cool to the touch. There are loops on each corner, too, which keep your duvet in place while you move. 

The biggest downside is that it's a little high-maintenance. Since the Down Comforter is not machine-washable, you'll have to stick to spot-cleaning or send it to the dry cleaners.
