Out of this world comfort

Truly born from space, Slumber Cloud bedding is infused with the same temperature regulating technology NASA astronauts used in their spacesuits. This patented technology, called Outlast® technology, is made up of thousands of microscopic “beads” called Thermocules™. Each individual bead is set to a specific temperature to counter any temperature fluctuations you might experience during the night. As your temperature increases, the beads absorb and store any excess heat away from your body to keep you cool. If your temperature drops, the beads release the stored heat back to you to keep you at the perfect temperature. The end result is a better night’s sleep with bedding that helps you sleep more comfortably, sweat less, and wake up feeling refreshed.

WHY WE USE OUTLAST® TECHNOLOGY

Cools Hot Sleepers

It’s just plain frustrating to keep waking up night after night, soaked with sweat and unable to get back to sleep. Many people of all ages and body types suffer from night sweats. Outlast® technology keeps you at the most comfortable temperature throughout the night… so you sleep cooler and more comfortably.

Helps With Hot Beds

Love your bed, but not all the heat buildup? Although they can reduce pressure points, beds with memory foam often get uncomfortably hot. Outlast® technology helps prevent the heat from your mattress from building up. You'll still enjoy the comfort of your mattress but without that hot, sweaty feeling.

Controls Humidity

When humidity develops in your bedding, your body sweats raising the humidity even higher. This causes you to wake up and push the covers off to "release" the humidity. Later you wake up again, this time too cold without the covers. Outlast® technology mitigates heat and humidity so there's no more pushing and pulling at the covers.

Wake Up On The Cool Side Of The Bed

With three types to choose from, you can easily find the perfect building block for the rest of your bed ...let us help you find the best foundation for your bed.

Threads That Count

Instead of obsessing over the number of threads, we focused on finding the right kind of threads for the best set of cooling sheets. A high thread count sounds luxurious, but more threads usually means lower quality fibers and heavier, less breathable sheets.

For the softness and durability of cotton plus the breathability and temperature regulation you find in the most luxurious sheets, we chose a 350 thread count blend of NASA-approved Outlast® viscose and premium cotton fibers. The end result is crisp and perfectly weighted sheets with space age temperature regulation so you can put an end to waking up in a hot and sweaty mess.

Cumulus comforter

We've Got You Covered

Born from space, the Cumulus Comforter uses Outlast® technology originally developed for NASA to control the microclimate of your bed (the space between your mattress and top covers). By automatically absorbing, storing, and releasing heat as the temperature under your covers changes, this comforter fights off the one thing that makes you sweat at night - humidity.

Pushing and pulling at the covers is typically a result of humidity developing in your bed's microclimate. To stabilize humidity and reduce sleep disruptions, the Cumulus Comforter harnesses the moisture regulating power of ClimaDry™ by Outlast. We carefully encased this space aged fiberfill in a soft and breathable 300 thread count 100% cotton outer shell. Two fill wights lets you pick and choose the weight that is perfect for you and that keeps you consistently comfortable and cozy, but never clammy.

Cumulus lightweightcomforter

Lightweight Comforter

Coming soon... A lightweight option that you can still leave on your bed year round, the Lightweight Comforter is designed to reduce overheating and sweating before you get too hot. You'll spend more time sleeping and less time pushing and pulling at the covers.

Cumulus comforter

Comforter

More of a 3 season comforter, this option adds the weight you want on your bed without any of the excess heat and moisture buildup. Ideal for sleepers who like a bit more weight on top of them or who live in colder climates when the outside temperatures dip below zero and the house just can't stay warm, but still don't want to wake up in a hot and sweaty mess.

Show Your True Colors

Protect your duvet or comforter without overheating, the Stratus Duvet Cover feels as good as it looks. The same temperature regulating technology NASA astronauts used in space is now available in for your bed. This duvet cover features a 300 thread count blend of unique temperature regulation of NASA-engineered Outlast® fibers and premium cotton for softness and durability. Designed to fit over your duvet or comforter almost like a “pillowcase”, with corner ties and a button closure, this cover sets the ideal conditions for cooler, deeper sleep, to put an end to sleep disrupting overheating and humidity build up.

Wrap Your Head Around This

Like mini space suits for your pillows, a simple zip is all it takes to upgrade the comfort of your pillows with NASA engineered cooling technology. Dual layers of Outlast® technology means the Nacreous Pillow Covers will help even the hottest of sleepers stay cool and comfortable all night long. It all starts with a heavily coated Outlast® lining fabric on both sides to reduce heat buildup. For maximum cooling performance, we then integrated an extra loading of Outlast® technology to the 350 thread count top cover for the greatest heat absorption.

The Cool Side

Infused with a heavy coating of space aged Outlast® technology, the 300 thread count 100% cotton outer shell keeps your head cool by absorbing, storing, and releasing heat as your temperature changes throughout the night. One squeeze is all it takes to fall in love.

The backbone of the Cirrus Pillow's construction is the inner fiber fill. With two fill types and 3 firmness levels to choose from, we make it easy to get the perfect pillow for your needs.

Cirrus pillow
Down fill

American duck down

American duck down fill creates an adaptive, liquid-like feel that responds to your movements through the night. This natural fiber is resistant to clumping, meaning it can bounce back to life with just a quick fluff.

Polyester fill

Polyester fiberfill

Polyester fill fortifies the pillow’s shape and evenly distributes the fill, creating a consistent loft. It also provides optimal neck support for better spine alignment.
