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.


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.”

Our Crib Mattress Protector comes with an 8" pocket. It's designed with an elastic strap to secure tightly on mattresses with varying depths from 5'' to 10''

The Outlast® Technology is a Oeko-Tex Standard 100 Certified Technology meaning there are no harmful chemicals.

Yes! The basis of the technology was originally founded and used by NASA. It even holds a Certified Space Technology Foundation seal of approval!
