Why It's Different

Most companies that claim to have cooling, sweat-wicking bedding only attempt to manage temperature once you've already become uncomfortable. Slumber Cloud is doing something different.

Slumber Cloud Bedding utilizes Outlast® technology for a proactive, not reactive, approach to temperature regulation. Outlast® technology regulates heat to stop moisture from developing in the first place, instead of attempting to wick away sweat that has already developed.

Not too hot…not too cool…just right.


A comforter tends to be a bit heavier in weight than a blanket and although they often are used in a single layer, they can be used inside a duvet cover for a more finished look. Similar to a comforter, a duvet is type of blanket that is generally lighter in weight and is used inside a duvet cover making it easy to care for.

Slumber Cloud products are designed to help manage heat and humidity build up. It is not an air conditioner with a set temperature degree, but it will react to your temperature all night long to reduce heat build up and manage temperature swings.

Definitely! When you sleep hot but your partner sleeps cold we refer to this as being “thermally incompatible”. Our bedding is designed to automatically adjust to each sleeper’s ideal sleep temperature. With the unique ability to react to each sleeper's temperature independently, our bedding ensures that both you and your partner will sleep comfortably all night long.

Although both duvet cover options are designed to help you sleep cooler and more comfortable, it's important to choose the version that best suits your sleeping needs. Below is a quick overview of each option to help you in this decision making:

Essential Duvet Cover:
The blend of cotton and Outlast® temperature-regulation viscose fibers offers a traditional super soft cotton feel. Ideal for those who prefer a more classic sheet but want temperature-regulation performance.

Performance Duvet Cover:
The blend of premium Tencel® and Outlast® temperature-regulation viscose fibers offers a buttery, silky performance feel. Ideal for those who prefer silky smooth softness with the most temperature-regulation performance.
