Why We’re Different

Proactive Technology

Other sheets only get to work after you get too hot, but by then you’re already sweaty and restless. Our sheets are different. Our bedding uses Outlast® technology for an unmatched approach to temperature regulation. This technology designed for NASA absorbs, stores, and releases heat when you need to warm up and cool down to keep you asleep.

Ready to wake up to a more rested life?

Most frequently asked questions.

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.

How does the technology in the bedding work?

Outlast® technology is made of a unique material that can absorb, store and release excess heat. As an individual’s skin temperature increases, the technology will absorb that excess heat to help reduce overheating. The material will store the excess heat until the skin temperature begins to drop. When this occurs, the stored heat is released back to the individual to prevent chill.

By managing the build-up of heat and moisture under the covers, Outlast® technology helps keep you at a comfortable temperature so you sleep “just right.”

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.

What's the difference between Slumber Cloud bedding and other "cooling" bedding I might have tried?

Slumber Cloud takes a proactive approach to temperature control by absorbing and storing excess heat when temperatures are too warm and releasing heat when temperatures are too cold. This approach is different than most other "cooling" bedding technologies/products on the market that are moisture-wicking (ex. Bamboo & Eucalyptus).

Moisture-wicking is a reactive approach because it doesn't start to cool you down until you build up sweat and moisture and then wicks it off of you. Our products are designed to prevent you from ever getting to the point of sweating and building up moisture.

What comes in a sheet set?

Our sheet sets come with 1 fitted sheet, 1 flat sheet, and pillowcases.

Twin and Twin XL sets come with 1 standard-size pillowcase.

Full and Queen sets come with 2 standard-size pillowcases.

King and Cal-King sets come with 2 king-size pillowcases.

What's the difference between the Essential Sheet Set, the Performance Sheet Set, and the Flannel Sheet Set?

Although all three sheet 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 Sheet Set:

- 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 Sheet Set:

- 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.

Flannel Sheet Set:

- The blend of brushed cotton and Outlast® temperature-regulation viscose fibers offers a heavier super soft brushed flannel hand feel. Ideal for those who want a thicker, warmer sheet with temperature-regulation performance.

Can I purchase the flat or fitted sheet separately from a set?

Currently, our sheets are only sold in sets which include the flat sheet, fitted sheet, and pillowcase. However, additional pillowcases are available for purchase.

How deep is the pocket on the fitted sheet?

Our fitted sheets come with 15" pockets. Fitted sheets are designed with an elastic strap to secure tightly on mattresses with varying depths from 5'' to 18''

Is this machine washable?

Yes! Just like traditional bedding, Slumber Cloud products are designed to be washed and dried in your home washer and dryer. Please carefully follow the care instructions on the tag of your products.

Can I use an iron on my bedding?

The technology in our bedding is sensitive to high heats - instead of ironing we recommend using a wrinkle release spray such as Iron In a Bottle for that crisp and finished look.

How do I sanitize my bedding?

Although we recommend against using high heat when washing your bedding there are products that can help with sanitizing your bedding. Here are a few of our favorites: Dropps & Tide

How should I remove stains?

Please refrain from using harsh chemicals such as bleach and oxiclean on your bedding. Instead opt for more natural alternatives such as a small amount of dish soap, a warm water & vinegar solution, or specialty formulated laundry detergent such as Dropps

How do I wash my Essential Sheet Set?

To wash your sheet set, please follow the washing instructions on the tag. If you have cut your tags after purchase, then it is recommended to wash with Slumber Cloud Free & Clear Laundry Detergent or a mild detergent in cold water on a delicate spin cycle.

When it’s time to dry your sheets, please dry it on low heat or air dry. Do not iron your sheets. To reduce wrinkling, take your sheets out of the dryer and immediately place on your bed or use a wrinkle release spray such as Iron In a Bottle for that crisp and finished look.
