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.

FAQ

Not to be confused with pillowcases, these pillow covers are traditionally used underneath your pillowcases to keep your head cool and extend the lifetime of your pillows.

Yes, we want your bed to look nice and match the rest of your linens so we made sure the technology inside our pillow covers will still work even when used with a pillowcase.

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.

The Single Pack option comes with one pillow cover. The Two Pack comes with two pillow covers. That means one for you and one to share with your partner (or not share, we don’t judge).
