There are quite a few vegan duvets out there.
Just about any big home supply store should have at least a few (e.g T.J.Maxx, Home Sense, Bed Bath & Beyond, etc.).
What you’re mainly looking for are “down alternative” duvets.
The most common vegan duvets are made from synthetic materials like polyester.
If you’re looking for a more eco-friendly alternative, you can try to find a cotton duvet, but mostly you’ll just find cotton duvet covers.
There are some bamboo duvets, but they cost a lot more than synthetic ones.
Here are a few popular options to get you started on your search.
Synthetic (e.g. Polyester, Microfiber) Duvets
This first duvet is made by Utopia, who happens to sell a variety of vegan-friendly bedding materials.
It’s a best seller that I’ve seen highly recommended in online vegan groups I’m a part of.
This is just the insert, you’ll need to buy a separate (but optional) cover.
It’s soft and machine washable (not all others are).
The second option here is the Panda ECO Hypoallergenic Comforter.
It’s a popular and inexpensive duvet made of microfiber fabric.
Again, very highly rated.
Bamboo (e.g. Viscose, Tencel) Duvets
A caveat before we look at an option for a bamboo duvet: The most common bamboo duvet material is viscose (a type of rayon). Rayon isn’t particularly eco-friendly if that’s why you’re looking for a synthetic alternative.
Something to be aware of, and may make it harder to justify the much higher price.
Cariloha makes a 100% viscose duvet from bamboo. It’s quite expensive, but very highly rated.
However, maybe the cost is worth it. It’s quite a breathable material, and super soft, making it a good option year round.
Cotton Duvet Covers
Unfortunately, not many duvets themselves are made from cotton.
They are hard to find, and typically only available from certain specialty stores that vary from country.
The majority of cotton duvet products are just covers.
For example, here’s a highly rated cotton duvet on Amazon.
It looks great, is highly rated, and can go over synthetic duvets to increase their longevity.
Unfortunately, that’s about all the options we have for now, hopefully that will change in the future.
