Our story
Wake up to a more rested life.
We make inventive, temperature-regulating bedding for the people who have tried everything and still wake up too hot, too cold, or simply not rested enough.
Meet our best sellersDenver, Colorado · Since 2013
We started with one stubborn problem: the bed was too hot.
We founded Slumber Cloud after noticing how many everyday things stood between people and a truly restorative night: overheating, sweating, freezing, tossing, turning, and the morning fog that follows.
Instead of making another “cool-feeling” fabric, we partnered with sleep-technology innovators to bring genuine temperature regulation into the home. Our goal was simple: take advanced material science, make it easy to understand, and put it within reach of more sleepers.
Then we built a Denver team of real people to stand behind it. Because better products deserve thoughtful service before, during, and long after your first night.

What we’re famous for
A better night’s sleep because of science.
Outlast® phase-change material began with NASA-funded research for spacesuit gloves. Today, it is built into our bedding to absorb excess body heat, hold it, then release it as you cool down.
Absorb
Takes in excess heat before it builds
Store
Holds that energy away from your skin
Release
Returns warmth as your body cools
Choose your feel
One temperature technology. Three very different fabrics.
Our Performance sheets share Outlast® temperature regulation. The difference is how you want your bed to feel.

Innovate
We look beyond ordinary bedding for materials and ideas that solve real nighttime problems.
