The Smart Topper - Cooling Mattress Topper

Yes it does, unlike some of our competitors. 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 cotton, bamboo or linen. 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.

Dual zone Smart Toppers have controllers on both sides, left and right.

When ordering a Twin XL, there are two options: "Twin XL" and "Twin XL-Left." "Twin XL" has the controller on your right hand side if you are lying in bed on your back. "Twin XL-Left" has the controller on your left hand side if you are lying in bed on your back.

"Twin XL-Left" is the only single zone Smart Topper with the manual controller on the left hand side.

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.

The cover of the Smart Topper can be washed.

The Smart Topper is nearly silent when cooling is at a low level. At 50% level of cooling it’s equivalent to a forced air household heating noise. 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. If you're sensitive to sound, there is a fan limiter setting in the app that constrains the fans to run at a maximum speed of your choice.

Yes! We designed the Smart Topper to be thin enough to retain the comfort characteristics of your existing bed, however, if you have a particularly soft bed will notice that the Smart Topper makes your bed firmer.

We offer free shipping within the USA and Canada on all Smart Topper orders.

All cooling mattress toppers (including subcooling water systems) are impacted by ambient room temperature, in different ways and for different reasons.

At high ambient temperatures of 80F, testing showed Perfectly Snug had 102% more cooling power than our top water-based competitor with only one side on; and 256% more cooling power than our top water-based competitor while one side of the bed was set to cooling mode and the other side set to heating mode

This makes Perfectly Snug the best cooling system at high ambient room temperatures. In contrast, water based cooling systems are prone to generating condensation at high ambient room temperatures, and actually increase the temperature of your room as the night progresses.

The Smart Topper cools using room-temperature air, and is most effective in a room of up to 79F/26C. If the room temperature is above this, the cooling is less effective but not ineffective. Your bed will be the coolest place in your room.

The Smart Topper can allow you to spend less on AC. It uses very little energy, averaging 20 W to cool each side of the bed - about 2 cents per night!

Please note that the Smart Topper does not replace air conditioning or heating as it does not change the temperature of the room overall.

The Smart Topper is 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 requires specially developed technology and materials. 

The Smart Topper is a high quality, North American made product that comes with a high level of service and care.
