To get the absolute most out of your Smart Topper's cooling, here are some helpful tips.
Breathable Sheets and Smart Topper Positioning
You can test breathability by holding your sheet to your nose and mouth to see how easy it is to breathe. A breathable duvet cover works best too, and it's not ideal to have blankets firmly tucked at the foot.
Manual Controller Placement
If your Smart Topper's plug is at the foot of the bed, you have it upside down/backwards. It will not work properly this way.

Sleep in the Zone
The temperature sensors are in the centre of a Single Zone (Twin, Twin-XL, Double), and on the right or left side of a Dual Zone (King, California King, Queen, Split King). Sleeping in the centre of a Dual Zone won't give the best experience.
Fan Limit Adjustment
The Fan Limit can be made higher or lower, depending on how sensitive you are to noise and how easily you feel chilled. (These settings are found by clicking the gear icon.)
Full power cooling: Slide this all the way to the right.
Gentler, more consistent cooling: Slide midway around 30–50%, with a colder Sleep phase Level (make the second number on your Home screen anywhere from Level -6 to -10).

Make your Start Phase warmer than Sleep Phase
The Start Phase will run the fans at a constant rate if the setting is below 0 (Level -1 = 10% speed, Level -5 = 50%, etc.).
Once you reach Sleep Phase, the Smart Sensors read your temperature. Level 0 represents normal comfortable skin temperature, and every level above or below that is approximately 1 degree warmer or cooler. The Smart Topper works much like a thermostat.
Tip: If your body isn’t warm enough to trigger cooling, the fans will turn off temporarily to prevent overcooling.
Disable Heaters (optional)
Not recommended for most sleepers. This is only advised if you never want your Smart Topper to warm you.

Constant Fan Mode (Non-Responsive Cooling)
Not recommended for most sleepers.
1) Click the clock icon for your Scheduler settings.
2) Change your Start Duration to 600 minutes, then set your Start Temperature to your preferred fan speed on the home screen. (e.g., -5 = 50% fan speed, -7 = 70%, -10 = 100%).
This will keep the fans running at a constant speed, as detailed in the tutorial PDF. [Best viewed in Chrome or a PDF viewer.]
