Out of this world comfort

The secret behind Slumber Cloud bedding is the patented temperature regulating technology called Outlast® technology built right into our products. Originally designed for NASA astronauts to regulate their temperatures in space, Outlast® technology is made up of thousands of microscopic "beads" called Thermocules™. Each one of these Thermocules™ is designed to absorb, store, or release heat to keep you in your ideal sleeping temperature zone.
