No more night sweats.
"Buying this along with the comforter was the best thing I've done in a long time! No more night sweats, not too hot, and not too cold!" - Ellen E.
Beautiful duvet covers
"I love these so much that I have two and plan on buying a third. These are the highest quality covers that I have ever had and the only ones I want to use." - Melanie E.
Very soft and smooth.
"I love how cool it is to the touch before you jump into bed. It hasn't heated up like other duvet covers thanks to the Outlast material. I can't help but run my hands across it whenever I walk past my bed during the day!" - Kevin T.
"Does what it says. I don't sweat with this duvet cover. I have it over an allergy comforter in which I know retains more heat than normal but with this cover it definitely helps. Looking to buy the sheets and the mattress cover next!" - Jennifer K.

Why we're different.
Traditional bedding and moisture wicking technologies react to changes in your body temperature while you sleep. Slumber Cloud is doing something different.
Slumber Cloud Bedding utilizes Outlast® technology for a unmatched approach to temperature regulation. Outlast® technology is proactive, not reactive. As your body temperature increases during sleep, Outlast® technology stores that heat to keep you cool, and then releases it as you cool down...keeping you feeling “just right”.
More than thread count, NASA-approved Outlast® fibers adapt to fluctuations in your temperature for an innovative approach to maximum sleeping comfort.
Tencel® fibers offer a silky smooth feel and moisture wicking properties for the most comfortable night's sleep.
Outlast® materials improve comfort for:
Anyone looking for a more comfortable night’s sleep - they’ll sleep cooler!
Women experiencing menopause - hot flashes and resulting night sweats are reduced so they sleep cooler and drier.
Thermally incompatible couples - individuals sleep at their own ideal temperature
The thoughtfulness is in the details.
It doesn’t stop at threadcount. It’s the little things, the thoughtful details, that make our products the best available.

Most frequently asked questions.
Definitely! When you sleep hot but your partner sleeps cold we refer to this as being “thermally incompatible”. Our bedding is designed to automatically adjust to each sleeper’s ideal sleep temperature. With the unique ability to react to each sleeper's temperature independently, our bedding ensures that both you and your partner will sleep comfortably all night long.
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.”
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.
Slumber Cloud takes a proactive approach to temperature control by absorbing and storing excess heat when temperatures are too warm and releasing heat when temperatures are too cold. This approach is different than most other "cooling" bedding technologies/products on the market that are moisture-wicking (ex. Bamboo & Eucalyptus).
Moisture-wicking is a reactive approach because it doesn't start to cool you down until you build up sweat and moisture and then wicks it off of you. Our products are designed to prevent you from ever getting to the point of sweating and building up moisture.
A comforter tends to be a bit heavier in weight than a blanket and although they often are used in a single layer, they can be used inside a duvet cover for a more finished look. Similar to a comforter, a duvet is type of blanket that is generally lighter in weight and is used inside a duvet cover making it easy to care for.
Yes! Just like traditional bedding, Slumber Cloud products are designed to be washed and dried in your home washer and dryer. Please carefully follow the care instructions on the tag of your products.
The technology in our bedding is sensitive to high heats - instead of ironing we recommend using a wrinkle release spray such as Iron In a Bottle for that crisp and finished look.
Please refrain from using harsh chemicals such as bleach and oxiclean on your bedding. Instead opt for more natural alternatives such as a small amount of dish soap, a warm water & vinegar solution, or specialty formulated laundry detergent such as Dropps
To wash your Essential Duvet Cover, please follow the washing instructions on the tag. If you have cut your tags after purchase, then it is recommended to wash with Slumber Cloud Free & Clear Laundry Detergent or a mild detergent in cold water on a delicate spin cycle.
When it’s time to dry your sheets, please dry it on low heat or air dry. Do not iron your sheets. To reduce wrinkling, take your comforter out of the dryer and immediately place on your bed or use a wrinkle release spray such as Iron In a Bottle for that crisp and finished look.
