Out of this world comfort

Say goodnight to overheating and night sweats. Engineered from space suits - now tailored for your bed, Slumber Cloud bedding utilizes NASA-inspired Outlast® temperature regulating technology for the most advanced sleep system on the market. Here's how it works...

One Giant Leap For Sleep

Like you, NASA astronauts were having issues regulating their temperatures. NASA turned to Outlast Technologies to solve this issue and so did we.

Throughout the night your body goes through natural fluctuations in temperature. Outside influences, like your bedding and physical makeup, severely impact how well you can process these fluctuations in temperature. When your temperature falls outside your ideal comfort zone, such as overheating, it causes you to wake up impacting your quality of sleep.

Slumber Cloud bedding with the same Outlast® technology NASA used in space, automatically adjusts to these temperatures fluctuations to help you sleep in your ideal comfort zone throughout the night. Let us break it down.

Slumber Cloud bedding

With proactive Outlast© technology, Slumber Cloud bedding is working continuously to reduce overheating and sweating before you get too hot. Slumber Cloud bedding with Outlast® technology manages heat to mitigate the onset of sweat, helping you sleep more comfortably, longer.

Traditional bedding

Traditional bedding traps heat and moisture under the covers. As heat builds up, you overheat and sweat, which causes sleep disturbances such as waking, pushing the covers off, and sticking a leg out. After overheating and your bedding soaked in sweat, your body begins to cool down and you become too cold.

Wicking technology

With reactive "wicking" technologies, you must first sweat and be in contact with the fabric for it to provide a benefit. After the sweat is wicked away and your bedding is soaked in sweat, you go through a rapid cool down. This affects your sleep by putting you in a constant battle of being either hot and sweaty or too cold.

It's rocket science

Some call it magic, but the secret behind Slumber Cloud bedding is the patented temperature regulating Outlast© technology built right into the fabric of our products. Made up of thousands of microscopic “beads” called Thermocules™, each one of these beads is designed to absorb, store, or release heat based on your ideal sleeping temperature.

As your skin temperature increases, the technology will absorb that excess heat to reduce overheating. The technology will then store the excess heat away from your body until your skin temperature begins to drop. When this occurs, the stored heat is released back to you to keep you at the perfect temperature.

Slumber Cloud products made with more Outlast© technology, or layering your bed with multiple Slumber Cloud products increases the heat absorption and temperature regulation abilities for improved performance.

The key to happy naps

Feeling hot and sweaty while you sleep? Although there are hundreds of reasons why you might be overheating we’ve broken down the three most common reasons - your body, your mattress, and humidity, and how the technology in our bedding helps solves those issues.

Hot sleeper

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 and chronic sleep disruption caused by overheating.

With Outlast® technology you get the perfect, most comfortable temperature throughout the night… so you’ll sleep better than you have in years.

Hot Sleeper Examination

Above are infrared images taken of two sleepers when they first climb in bed with Outlast® technology and after they have laid in bed for identical periods of time. You can see that the two sleepers have different sleeping temperatures with the woman on the left being significantly warmer.

Because Outlast® materials are able to absorb and store excess heat, there is a reduction in build-up of heat and moisture next-to-skin for both sleepers. And the Outlast® technology adapted to the ideal sleeping temperature for both sleepers, keeping them not too hot and not too cold.

Hot mattress

Love your bed, but not all the heat buildup? Although they can reduce pressure points, beds with dense materials like memory foam often get uncomfortably hot. While you’re at it, you might also want to examine the other layers of your bed. Overly insulated blankets and high thread count sheets can trap heat in your bed causing you to overheat.

Slumber Cloud bedding with 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 for a higher quality sleep.

The Hot Mattress Study

This study investigated the impact that Slumber Cloud bedding has on a person’s sleep experience. This study measured both physiological and psychological responses and body motion during sleep.

For the nights that test subjects slept on traditional mattress pads, subjects reported poor sleep and an increase in temperature that made them feel too hot. The increased temperature caused them to unconsciously move their bodies, an action done to adjust to fluctuations above or below an optimal sleep temperature. Information recorded for the nights in which mattress pads with Outlast® technology were used resulted in less movement, verses the nights in which regular mattress pad was used.

On average, subjects also recorded an increase in sleep depth and felt well-rested when sleeping on the mattress pad with Outlast® technology. Mattress pads with Outlast® technology proved to create a sleep environment that offered deeper, more restful sleep.

Humidity & Microclimate

Most people associate sleep disturbances with being too hot. We partnered with Outlast Technologies to understand what really causes you to toss and turn all night. By conducting sleep tests in stabilized temperatures, we discovered that humidity in your beds microclimate was the real source to the tossing, turning, and throwing off of covers.

The microclimate a.k.a. the space between your mattress and top cover, is the key to a more comfortable night's sleep. Regardless of your room temperature, when humidity develops in your beds microclimate, your body overheats and begins to sweat, raising the humidity in your bed even higher. This causes you to naturally wake up and push the covers off to "release" the humidity. A few hours later you wake up again, this time too cold without the covers.

Our bedding utilizes Outlast® technology to help mitigate the buildup of heat and humidity for increased comfort and a better night's sleep. No more pushing and pulling at the covers trying to find the perfect temperature.

The Humidity Study

In this test, sweat was measured in terms of humidity. Live, and almost in real time, THG Sleep View technology measures the microclimate of a person’s sleep environment (the development of heat and humidity). With the help of THG Sleep View technology, researchers determined that individual comfort is considerably affected by the microclimate around the body during sleep. Increased humidity created discomfort and caused stress for the test subjects and reduced the body’s ability to stay cool, therefore causing sleep disturbances such as tossing and turning, waking up, and pushing the covers off.

Outlast® materials yielded lower humidity and temperatures than the control materials. These improved microclimates, due to the use of Outlast® technology, produced better quality and deeper sleep than the control material. It proves that the use of Outlast® technology in bedding, such as sheets or comforters, can help mitigate the build up of humidity for increased comfort.
