“As a clinical psychologist and insomnia specialist, I found that the Perfectly Snug Smart Topper helps in reducing sleep disturbances and improving sleep efficiency.”
Imagine a Life with Consistently Great Sleep

The world's first Smart Topper that adjusts cooling & heating while you sleep.
The Perfectly Snug cooling mattress topper is a 2-inch layer that sits on top of your mattress, while quiet internal fans propel cooling air under and against your body. Cooling and heating automatically adjust based on built-in sensors to keep you at your preferred temperature all night long. Includes a Cold Burst function that delivers instant cooling relief when you need it most.

Yes it does! This is one of our most convenient features. We recommend using our bed-corner straps (included with the topper) to hold it in place.
The Smart Topper works with all breathable sheets. We recommend a tight-fitting cotton, bamboo or linen with lower thread count. Try breathing through the sheets and if it is easy then it will work! We don't recommend using mattress protectors over the Smart Topper or it will hinder the airflow.
The manual controller is embedded in the side of the Smart Topper and is designed to be used by touch through your fitted sheet.
Dual zone Smart Toppers have controllers on both sides, left and right. They are used by touch through your fitted sheet.
"Twin XL-Left" is the only single zone Smart Topper with the manual controller on the left hand side. You can view a diagram in the size selection section on our Shop page.
The Smart Topper can be used manually without any app or network connections, but functions best when set up using the free app.
The Perfectly Snug App requires:

Yes! Perfectly Snug is the best and fastest cooling mattress topper at all room temperatures.
All cooling systems (including subcooling & water systems) are impacted by heat. At room temperatures of 80F, Perfectly Snug had 102% more cooling power than our water-based competitor with only one side on; and 256% more cooling power than our water-based competitor while one side of the bed was set to cooling and the other set to heating mode. (Our full Performance & Specs can be found on our Shop page.) We're the best for couples!
Water based & subcooling systems can create condensation in warm environments, and their machines can increase the temperature of your room as the night progresses.
The Smart Topper's cooling technology ensures your bed will be the coolest place in your room. Please note that the Smart Topper does not replace air conditioning or heating as it does not change the temperature of the room overall.
Not at all! Our Perfectly Snug Smart Toppers are ambient neutral. There is no decrease or increase of humidity in your bedroom, no risk of condensation, and no external machine that will make your room hot.
Nope! Aside from the simple cord and plug that hide behind the head of your bed, the Smart Topper is entirely self-contained. No hoses, no machines on your floor.
The manual controller is embedded in the side of the Smart Topper and is designed to be used by touch through your fitted sheet.
The Smart Topper cools you down and warms you up a minimum of -10 or +10 degrees of skin temperature. (Based on average human skin temperature.)
The Smart Topper is nearly silent when cooling at a low level. At 50% cooling it’s like the quiet whoosh from a home furnace. At full cooling, it sounds similar to a stand-alone fan running in the room.
The level of cooling selected will determine how loud the fans will run. There is a fan limiter setting in the app for sensitive sleepers.
Yes! We designed the Smart Topper to be perfectly medium firm. You may experience it as firmer at first, so give it time! A transition period is perfectly normal and will pass. You and your body are learning your new sleep habitat. You'll be glad you did!
The fans are located at the very foot of the Smart Topper. You can view a diagram in the size selection section on our Shop page.
The Smart Topper is powered by low voltage DC power from a power brick that plugs into any standard wall outlet. The power supply will work in any country.
Yes! The cover of the Smart Topper can be spot cleaned, and this is the simplest way to care for it. The cover can also be fully removed for washing.
Learn more about washing details here.
Yes! Cats and dogs can join you on your Smart Topper - so long as they are potty trained!
No, there is no ongoing maintenance. Simply plug it in, switch it on, connect, and enjoy!

The Smart Topper is more affordable than water based cooling pads that can leak, require a lot of maintenance, and can cause mold leading to health concerns.
It's also much more than a mattress! A mattress can't actively cool or regulate your temperature. Unique features like adaptive cooling and heating, smart sensors to monitor your temperature, and scheduled sleep settings require specially developed technology and materials.
