What We Like
  • Reasonably priced

  • Soft shell

  • Lightweight yet cozy

  • Eco-conscious materials

What We Don't Like
  • Inexact sizes

  • Not dryer-friendly

Our number one pick is the Buffy Cloud Comforter. It earned a 4.8 out of 5 overall score from our at-home tester, who liked the soft, breathable shell and lightweight yet cozy fill. This vegan duvet scored 4s for fabric quality and durability, as it held up well in the wash, and 5s for softness and overall value.

Though the fill is a synthetic substance (polyester), it's sourced from recycled materials. And since the lyocell shell comes from the pulp of renewable eucalyptus trees, it's an all-around sustainable product.⁴ Breathable and not too hot but still plenty warm, this down-alternative comforter is ideal for year-round use.

We also like that it's machine-washable, but bear in mind hang-drying is recommended. One other thing to note is that the sizes aren't exact, which can make your duvet cover look a little baggy.

Material: Lyocell shell, recycled polyester fill | Sizes: Twin/Twin XL, Full/Queen, King/Cal King | Fill Power: Not listed | Care: Machine wash cold, hang dry

What Our Testers Say

"The all-season Buffy comforter we tried felt much lighter than the down one we’d been using, but it managed to keep us just as warm. Not too warm, though—and that was a real win." —Carrie Bluth, Product Tester

Utopia Bedding Comforter Duvet Insert

 Courtesy of Amazon

What We Like
  • Budget-friendly

  • Breathable

  • Corner loops

  • Several colors available

What We Don't Like
  • Not very lofty

  • Synthetic shell

The Quilted Comforter from Utopia Bedding earned a 4 out of 5 score from our home tester. She appreciated its breathability, cozy warmth, machine-washable design, handy corner loops, and supremely affordable price tag. This insert comes in six exact sizes, so you won't have to worry about excess fabric hanging off from your duvet cover.

In addition to white, it comes in eight different colors. So if you're not a fan of duvet covers, you can go without it and just rock one of these chic hues. This isn't the loftiest comforter on the market, but it's an excellent lightweight option for folks on a budget. Another thing to note is that the shell is microfiber (polyester), which isn't great at wicking away sweat.

Material: Microfiber shell, polyester fill | Sizes: Twin, Twin XL, Full, Queen, King, Cal King | Fill Power: Not listed | Care: Machine wash cold, tumble dry

What Our Testers Say

"We had no problems snoozing away under this cover, which kept our body temperature nicely regulated all night long. It’s light enough to throw on in the spring but maintains enough heat to take you through the winter."—Jill Waldbieser, Product Tester

Best Splurge: Cozy Earth Bamboo Comforter

Bamboo Comforter

Cozy Earth

What We Like
  • Natural material

  • Temperature-regulating

  • Two weights available

  • Corner loops

What We Don't Like
  • Expensive

If you're open to splurging on a truly amazing bed cover, Cozy Earth won't let you down. This entire comforter, including both the shell and fill, is made of bamboo-sourced viscose. The material is not only a sustainable, renewable resource, but it's also inherently breathable and exceptionally soft.

What's more, bamboo has natural temperature-regulating and moisture-wicking abilities. This makes it perfect for people who run hot or experience night sweats, though it's also plenty warm and cozy. And if you prefer a little more loft, upgrade to the "extra" fill level.

What Our Testers Say

"This comforter kept me warm on nights when temperatures dipped into the 40s and 30s.

But most nights, I was comfortable and cozy."—Sage McHugh, Product Tester

Brooklinen Down Alternative Cover

Brooklinen

What We Like
  • Long-staple cotton shell

  • Made from recycled materials

  • Corner loops

What We Don't Like
  • Inexact sizes

  • Not machine washable

Down-alternative duvets can be suitable for year-round use—"You just have to be careful that you're not purchasing one that is on either end of the weight scale," says Logan Foley, Managing Editor at SleepFoundation.org. Keeping this in mind, we recommend Brooklinen's All-Season Comforter, which the brand touts as the "Goldilocks of comforters."

In terms of construction, this duvet has a 100 percent long-staple cotton shell with a supremely smooth sateen weave. The polyester fill is sourced from recycled plastic bottles, and baffle-box construction ensures it's evenly distributed. One thing to note is that this bed cover isn't machine-washable—Brooklinen recommends spot-cleaning or dry-cleaning if needed.

What to Look for in a Down Alternative Comforter

Shell material

According to Foley, high-quality materials are paramount for down-alternative comforters, and it starts with the shell (the outside of the duvet). Natural fabrics tend to be the most breathable with moisture-wicking properties, which helps keep you at a comfy temperature while you doze. Cotton is the most common, but you'll also find options with bamboo, eucalyptus, silk, and lyocell shells.

Fill material

"Down-alternative comforters are a great option for people with allergies, as goose and duck feathers can cause allergic reactions," says Foley. "Vegans will also prefer a down-alternative comforter."

So, what are they filled with then? Ultra-fine polyester fibers are the most common replacement for feathers. Though this is a synthetic substance, it's often sourced from recycled materials, such as plastic water bottles. You'll also find duvets filled with natural materials, like viscose (bamboo) and silk—just keep in mind silk isn't vegan, as it comes from mulberry worms.

Weight and loft

In addition to the fill material, you'll want to consider the weight and loft. "A heavier comforter will be warmer," says Foley, "so consider using a light comforter if you're a hot sleeper or want to use it in the summer months."

If you like the fluffy look and feel of a plush comforter but don't necessarily want something super warm, there are some great lofty yet lightweight designs. Another option is to size up while using the proper duvet cover size. For instance, a king comforter will look super fluffy inside a queen cover without adding too much heat.

FAQ
  • What is the difference between a down and a down-alternative comforter?

    "Down comforters are filled with the soft clusters found underneath the feathers of ducks and geese," explains Foley. "Down-alternative comforters are not filled with any animal product and are instead filled with either synthetic (polyester, microfiber, etc.) or natural materials (bamboo, wool, etc.)." As mentioned above, silk is also a great substitute for down, though it's not technically vegan.

  • How do you wash a down-alternative comforter?

    The proper way to wash a down-alternative comforter really depends on the material, stitching, and overall construction. But generally speaking, you should be able to launder yours in a standard washing machine on a delicate cycle (or bulky, depending on the loft) with cold or warm water.

    Most duvet inserts can also be tumble-dried on low heat, though some call for air-drying. Additionally, some brands suggest spot-cleaning or dry-cleaning only, so be sure to check the instructions before cleaning yours.

  • When does a down-alternative comforter need replacing?

    Most down-alternative comforters last between three to five years, though it depends on the material, usage, and overall quality. If yours is lumpy, flatter than it once was, permanently stained, or has a funky odor, it might be time to swap it out for a new one.
