FAQs

What’s the difference between a duvet, comforter, and duvet cover?

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.

How many degrees cooler will this keep me?

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.

I sleep hot, my partner sleeps cold. Is this going to work for us?

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.

What's the difference between the Performance Cotton Duvet Cover, Performance TENCEL™ Duvet Cover, and the Performance Linen Blend Duvet Cover?

Although all 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:

The Performance Cotton 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 duvet cover but want temperature-regulation performance.

The Performance TENCEL™ Duvet Cover:

These sheets and duvet cover are so comfy and cozy! They really do keep me cooler at nights too; which I've been fighting with my entire life - I'm an overheater! I already recommended them to my best friend.

Perfect for California Summer! I love the lightweight and how well it regulates heat, so that we are not hot nor cold. It is perfection. I was hesitant because of the cost but glad that I decided to purchase it

I have bought countless pillows, new bed, different positions, tried couch, bought new couch. Got this ultra cool pillow, so soft, literally feels like sleeping on a nice cool cloud. Slept the full night, first full night in over a year.
