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”.
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.
Outlast® materials improve comfort for:
Anyone looking for a more comfortable night’s sleep - they’ll sleep cooler and more comfortably.
Sleepers who struggle with hot flashes and night sweats - proactive temperature regulation means they’ll sleep cooler and drier and wake up feeling refreshed.
Thermally incompatible couples - individuals can sleep at their own ideal temperature.
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.
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 pad on top of your mattress but under your fitted sheet. If you are using a mattress protector, layer that first followed by the mattress pad 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 the mattress pads?
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”.
Which product offers the best temperature-regulation?
If temperature-regulation is your main concern, we recommend the Core Mattress Pad. You may also want to consider layering your bed with multiple Slumber Cloud products to create your own “sleep system” designed to keep you at the perfect temperature all night long.
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.
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?
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 pad?
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.
Does Free Shipping Apply To International Orders?
Free shipping is only valid for US and Armed Forces delivery addresses. However, we do offer discounted shipping rates to Canada addresses.
Do you ship internationally?
Currently, we only ship internationally to Canada. At the time of purchase we include the cost of shipping, taxes, and duties for Canadian shipments. No additional fees will incur at delivery, but if they do please contact our customer service team at info@slumbercloud.com to take care of the issue. For all other countries, if you find a forwarder or have a friend or family member here in the states, we would be more than happy to work with you to get it there.
Can I still return an item even if it's been washed?
We accept returns in any condition within 60 days of purchase! We want you to absolutely love your new bedding, so if you wash an item, try it out, and decide it's just not for you, we can definitely still initiate a return. Please note we do our very best to donate all returns to local charities instead of a landfill. We appreciate your help in this process by washing any used items before returning them to us.
Are shipping fees covered for returns?
All shipping fees for domestic returns are completely free! When you initiate a return through our returns platform, you will receive a prepaid shipping label to get the item back to us. If you live outside the US and are looking to initiate a return, please check out the return policy in the International FAQs.
