Down-Alt Duvet

We strongly encourage using one! Similar to using a pillowcase with your pillow, protecting your Casper duvet with a duvet cover will help safeguard it against sweat, dirt, and stains — and it can easily be regularly thrown in the wash with the rest of your linens.

We designed the Down Duvet, Down Alternative Duvet, and Humidity-Fighting Duvet to work specifically with the Casper sheets, but you can also use your existing sheet set or duvet cover. Just be sure to double-check the dimensions, as our duvets were consciously designed to be slightly oversized.

To care for your duvet, machine wash in a large front-load machine in cold water on a gentle cycle. Then, tumble dry low with dryer balls (or clean tennis balls). Before removing from the dryer, make sure the duvet is completely dry before putting it back into the duvet cover.

Do not iron or dry clean the duvet, as certain chemicals can dry out the down clusters and cause them to break down faster and lose their resiliency and insulation properties.

If you don’t have a front-loading washing machine, don’t fret! Feel free to reach out to our customer experience team for alternate suggestions on how to clean your duvet.

Here’s the deal: a duvet is a type of bedding that’s commonly filled with down or wool materials. A comforter functions as a quilted blanket and is often filled with synthetic fibers. While both can be protected by duvet covers, comforters are more often sold with sheet sets.
