Q: Where is this manufactured? A: The Casper Duvet Insert is designed and assembled in the USA and produced with imported materials.

A light weight duvet will feel soft and snuggly, with no weight bearing down on your body, for a 'cloud-like' feeling when you're drifting off to sleep. Smartfil® duvets are lightweight yet thermally efficient. They feature more layers and better airflow, offering loft and drape.

The best duvet for summer is a low tog and lightweight duvet made with naturally breathable, sweat wicking materials. We recommend goose down for the duvet filling and 100% cotton for the duvet casing.

All three Casper duvets can be machine washed in cold water on a gentle cycle, and tumble dried on low. It's best to wash the duvet with similar colors to prevent other dyes from bleeding into the shell. Since each Casper duvet includes sewn-in chambers, the fill should hold its shape in the washer and dryer.

Casper mattresses are assembled in the United States. They're made from materials sourced in other countries, including Vietnam, India, China, Portugal, and France.

Laid-back linen is the lightest and most breathable duvet cover material - its naturally hollow fibers allow for ample air circulation. Any fabric made from natural materials will offer some amount of breathability.

Pick a Preferred Weight (Light, Medium, or Heavy) Thick, heavy inserts will be warmer, while light, thin inserts will be cooler. Medium-weight options are ideal for year-round use. Some brands make duvet inserts for hot sleepers who need to stay cool, like the Lightweight Comforter ($159-$219, Slumber Cloud).

Which duvet is best for winter? A 13.5 tog duvet is a good tog rating if you get cold in bed during the winter, a 9 tog if you want a medium temperature duvet and a 4.5 tog if you are a hot sleeper. An all season duvet offers the most versatility if you want a duvet you can use all year round.

This Casper down duvet is available in midweight or lightweight options, which is just how much fill is used. The lightweight will have less fill than the midweight, so it's a better option for hot sleepers or for use during warmer months.

How do I care for my Casper duvet? 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).

Casper Sleep (also known as Casper) is an e-commerce company that sells sleep products online and in retail locations. Headquartered in New York City, the company has showrooms in New York City, Chicago, and elsewhere. Its mattresses are manufactured in Georgia and Pennsylvania.

In 2020, Casper closed its European operations, and in the same year, it stopped selling mattresses directly to UK customers, both in a failed effort to achieve profitability.
