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 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.

The Smart Topper cools using room-temperature air, so, the cooler the room, the more effective the cooling effects will be. The Smart Topper is effective in a room of up to 79F/26C. If the room temperature is above this, the cooling is less effective as it will be using warm air.  

The Smart Topper can allow you to spend less on AC, by simply adjusting the temperature setting in your home by a couple degrees. 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.
