FAQs

The Performance Pillowcase Set comes with two pillowcases.

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.

Although all both 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.

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.”
