Why You'll Love It:

The ultimate combination of softness and breathability.
Award Winning Sleep

Touted for temperature. The Performance Sheets have earned high marks for their unique blend of proactive Outlast® viscose and reactive moisture-wicking TENCEL™ that keeps you from waking up too hot or too cold.

Stay-Put Design

The fitted sheet is designed with a full elastic band plus four corner straps to keep the fitted sheet from shifting and the corners from popping off.

Single-Ply Construction

The Performance Sheets have a single-ply construction with long staple fibers so you can rest easy knowing you are sleeping on high quality breathable sheets.

Why It's Different

Most companies that claim to have cooling, sweat-wicking bedding only attempt to manage temperature once you've already become uncomfortable. Slumber Cloud is doing something different.

Slumber Cloud Bedding utilizes Outlast® technology for a proactive, not reactive, approach to temperature regulation. Outlast® technology regulates heat to stop moisture from developing in the first place, instead of attempting to wick away sweat that has already developed.

Not too hot…not too cool…just right.


Although all both sheet 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:

Essential Sheet Set:
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 sheet but want temperature-regulation performance.

Performance Sheet Set:
The blend of premium Tencel® and Outlast® temperature-regulation viscose fibers offers a buttery, silky performance feel. Ideal for those who prefer silky smooth softness with the most temperature-regulation performance.

Currently, our sheets are only sold in sets which include the flat sheet, fitted sheet, and pillowcase. However, additional pillowcases are available for purchase.

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.

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.
