FAQs

Does this come with one or two pillowcases?

The Performance TENCEL™ Pillowcase Set comes with two pillowcases.

How many degrees cooler will this keep me?

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.

What's the difference between the Performance Cotton Pillowcases, Performance TENCEL™ Pillowcases, and the Performance Linen Blend Pillowcases?

Although all options are designed to help you sleep cooler and more comfortable, it’s important to choose the version that best suits your sleeping needs. Below is a quick overview of each option to help you in this decision making:

The Performance Cotton Pillowcases:
The blend of cotton and Outlast® temperature-regulation viscose fibers offers a traditional super soft cotton feel. Ideal for those who prefer a more classic pillowcase but want temperature-regulation performance.

The Performance TENCEL™ Pillowcases:
The blend of premium TENCEL™ lyocell and Outlast® temperature-regulation viscose fibers offers a buttery, silky performance feel. Ideal for those who prefer silky smooth softness plus moisture-wicking.

The Performance Linen Blend Pillowcases:
A blend of Outlast® temperature-regulation technology, viscose, and FLAX™ Linen fibers offers an elevated textured look and ultra soft handfeel. Ideal for those who want temperature-regulation with the luxurious look of Linen.

How does the technology in the bedding work?

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.”

These sheets and duvet cover are so comfy and cozy! They really do keep me cooler at nights too; which I've been fighting with my entire life - I'm an overheater! I already recommended them to my best friend.

Perfect for California Summer! I love the lightweight and how well it regulates heat, so that we are not hot nor cold. It is perfection. I was hesitant because of the cost but glad that I decided to purchase it

I have bought countless pillows, new bed, different positions, tried couch, bought new couch. Got this ultra cool pillow, so soft, literally feels like sleeping on a nice cool cloud. Slept the full night, first full night in over a year.
