Finally.

"I recently got a new memory foam pillow-top mattress that is super comfortable, but had me waking SOAKED in sweat. After a ton of research, I finally found this gem. And let me tell you, it really works. I've found that it does a great job at temperature-regulation." - Mimia W.

Why we're different.

Traditional bedding and moisture wicking technologies react to changes in your body temperature while you sleep. Slumber Cloud is doing something different.

Slumber Cloud Bedding utilizes Outlast® technology for a unmatched approach to temperature regulation. Outlast® technology is proactive, not reactive. As your body temperature increases during sleep, Outlast® technology stores that heat to keep you cool, and then releases it as you cool down...keeping you feeling “just right”.

Technology

Our premium lining fabric takes a proactive approach by employing active temperature control properties, versus other "cooling" bedding that is moisture-wicking and simply reactive.

Our Tencel® outer cover offers a silky smooth feel and moisture wicking properties for the most comfortable night's sleep.

Materials

Outlast® materials improve comfort for:

Anyone looking for a more comfortable night’s sleep - they’ll sleep cooler!

Women experiencing menopause - hot flashes and resulting night sweats are reduced so they sleep cooler and drier.

Thermally incompatible couples - individuals sleep at their own ideal temperature

Benefits

We pass on everything we learn to our customers. From sleep studies to new technologies, we want to help you make informed decisions about your sleep.

Most frequently asked questions.

I sleep hot, my partner sleeps cold. Is this going to work for us?

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.

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.

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 Slumber Cloud bedding and other "cooling" bedding I might have tried?

Slumber Cloud takes a proactive approach to temperature control by absorbing and storing excess heat when temperatures are too warm and releasing heat when temperatures are too cold. This approach is different than most other "cooling" bedding technologies/products on the market that are moisture-wicking (ex. Bamboo & Eucalyptus).

Moisture-wicking is a reactive approach because it doesn't start to cool you down until you build up sweat and moisture and then wicks it off of you. Our products are designed to prevent you from ever getting to the point of sweating and building up moisture.

What's the difference between a mattress pad and a mattress protector?

Although each of these products utilize Outlast® technology to help you sleep at the perfect temperature, each product addresses different needs. If you need the most temperature-regulation performance, one of our mattress pad options are right for you. If you need 100% waterproof protection and temperature-regulation, you should choose the mattress protector.

How do I layer a mattress pad on my bed?

The technology in our mattress pads is designed to work even when used underneath your fitted sheet. We recommend to layer the mattress protector on top of your mattress but under your fitted sheet. If you are using a mattress topper, layer that first followed by the mattress protector and fitted sheet.

Will this help even on my memory foam mattress?

Love your bed, but not all the heat buildup? Although they can reduce pressure points, beds with memory foam often get uncomfortably hot. Slumber Cloud bedding with 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.

How deep is the pocket of your mattress protector?

Made with a unique elastic skirting and a 360-degree grip, our pads and protectors perfectly fit any mattress as short as 5’’ and up to 20”.

Is this machine washable?

Yes! Just like traditional bedding, Slumber Cloud products are designed to be washed and dried in your home washer and dryer. Please carefully follow the care instructions on the tag of your products.

Can I use an iron on my bedding?

The technology in our bedding is sensitive to high heats - instead of ironing we recommend using a wrinkle release spray such as Iron In a Bottle for that crisp and finished look.

How do I sanitize my bedding?

Although we recommend against using high heat when washing your bedding there are products that can help with sanitizing your bedding. Here are a few of our favorites: Dropps & Tide

How should I remove stains?

Please refrain from using harsh chemicals such as bleach and oxiclean on your bedding. Instead opt for more natural alternatives such as a small amount of dish soap, a warm water & vinegar solution, or specialty formulated laundry detergent such as Dropps

How do I care for my mattress protector?

To wash your mattress pad, please follow the washing instructions on the tag. If you have cut your tags after purchase, it is recommended to wash with Slumber Cloud Free & Clear Laundry Detergent or a mild detergent in cold water on a delicate spin cycle. When it’s time to dry your mattress protector, please dry it on low heat or air dry. We recommend taking the mattress protector out halfway through a cycle to ensure that everything is moving around and one part is not constantly up against the heating element.
