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 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.

Engineered to prevent overheating and sweating while you sleep, this vital middle layer of the Slumber Cloud sleep system is not only a dream to sleep on, but maintains the microclimate of your bed for the ideal sleep environment.

Humidity

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.

Outlast Space certified

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.
Stratus sheets

Designed With You In Mind

Take your sheets to the next level. Smooth and super soft, as well as one of Good Housekeeping’s consumer testers favorite sheets, you’ll consistently wake up on the bright side of the bed. Each cooling sheet set includes a flat sheet, fitted sheet, and 2 pillowcases* for head to toe comfort. Wrap yourself in the comfort of ultra high quality, single-ply, sheets that instantly elevate the feel of your entire bed.

Thoughtful Details

It doesn’t stop at the threads. It’s the little things that make the Stratus Sheet Set the best cooling sheets on the market.
