Basic Care:
Machine wash cold water on a gentle cycle with a mild detergent and with like colors only. Tumble dry low heat until fill is completely dry. Remove from the dryer immediately. To maintain even distribution of fill, re-fluff or shake throughout the dry cycle. Only use non-chlorine bleach when needed. Do not dry clean. Do not iron.

Pro Tip:
Comforters should be washed every 1-3 months or as needed. Do not iron, bleach or dry clean your Comforter. Expect minimal shrinkage after the first couple of washes.

Why You'll Love It:

The good fluff.
The Perfect Partner

When you sleep hot but your partner sleeps cold we refer to this as being “thermally incompatible”. The filling inside our Comforter 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 Comforter ensures that both you and your partner will sleep comfortably all night long.

Cotton Touch

Inspired by a classic cotton comforter, our premium 100% cotton shell hugs your body so you stay cozy all night. Surround yourself with an elevated twist on a classic comforter.

Versatile Design

The Comforter is designed to be used as a bed cover and a duvet insert. If you prefer a finished look, the Comforter has 4 corner loops so that it can attach to a duvet cover. If you'd rather skip a duvet cover, no sweat.

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.


The difference between the two comforter weights is the amount of filling. The lightweight option is significantly lighter & thinner at about 1/4th'' thick, and is the best option for hot sleepers.

The comforter is more of a three season weight, and for those who prefer a bit more loft & thickness at about 2''. Both of the comforters are filled with Outlast technology to assist with keeping you cool with proactive heat management.

Our comforters are designed to regulate your temperature even when placed inside a duvet cover. Feel free to use a duvet cover to get the finished look you are after as it will not have a drastic impact on the overall performance. However, we do recommend the Essential Duvet Cover for an added layer of Outlast® temperature-regulation and breathability.

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.

A comforter tends to be a bit heavier in weight than a blanket and although they often are used in a single layer, they can be used inside a duvet cover for a more finished look. Similar to a comforter, a duvet is a type of blanket that is generally lighter in weight and is used inside a duvet cover making it easy to care for.
