 Good Enough For NASA

Pick the only pillow made of a unique material that can absorb, store and release excess heat. As your skin temperature increases, the NASA-engineered 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.

 Supportive Sleep

With two firmnesses, Soft/Medium and Medium/Firm, you can choose which support is best for your sleeping style.

Recommended:
- Stomach Sleepers: Soft/Medium
- Side Sleepers: Medium/Firm
- Back Sleepers: Medium/Firm

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.
