Visit the Apple App Store or Google Play Store and search for "Perfectly Snug Controller". Select the App and touch Install.

Occasionally, there may be updates to the App. If your device has been setup to automatically update apps, then you don't need to do anything. Otherwise, you may need to periodically check for updates.

This is the main screen you will use to set your temperature preferences.

1. Each side of the Smart Topper can be controlled by touching one of the tabs near the top of the screen.

2. The bed goes through three sequential phases during the night: Start, Sleep, and Wake. Each phase may be separately adjusted by touching the line and sliding it up and down. The number displayed indicates levels of cooling or warming. Cooling is indicated in blue, warming in orange.

3. Once the desired levels have been set, touching the grey Run Button will initiate operation of the Smart Topper and the button will change to blue.

If the Smart Topper has scheduling enabled (see Scheduler), then it will begin operating automatically at the preset bedtime.

4. The progress of the operation cycle of the air-conditioned Smart Topper is shown by the bar located near the bottom of the graphical display. The grey bar will turn blue from left to right to indicate the progress.

5. When the bed is running, the Run Button will change to a blue square stop button. Touching this button will stop the bed.

6. You can access the Settings Screen by touching the gear icon in the top right, where various parameters of the bed operation may be set, including scheduling.

7. You can access the Scheduler Screen by touching the clock icon near the bottom of the screen or by touching anywhere on the time bar.

8. You can pull up helpful information about how to use the App by touching the question mark icon.

9. When the bed is performing a cool burst, a snowflake icon appears near the bottom of the screen, and when it is performing a warm burst a sun icon appears. You can touch this icon to stop the burst.

1. You can go back to the Overnight Screen by touching the home icon.

2. You can go to the WiFi Screen by touching the WiFi icon.

3. Speaker Vol controls the volume of the audible feedback when the bedside buttons are used. Level 0 (slider all the way to the left) is off.

4. Fan Limit sets the maximum fan speed used during the Sleep and Wake phases. It has no effect on the Start phase or burst mode. Moving the slider left makes the bed quieter but also reduces the cooling performance. Moving the slider right increases cooling performance.

5. The Foot Heater has three levels. Level 0 (slider all the way to the left) is off.

6. If you never want the heaters to come on, then turn the Enable Heaters toggle off. This will stop preheating, foot heating, and automatic heating if you get cold. Normally the heaters should be enabled (toggle on) so that preheating, foot heating, and automatic heating work.

7. Cool Burst Level adjusts the strength of cool burst mode. Move this slider right to increase the airflow.  Move it left for less airflow.

8. Cool Burst Time sets the duration of cool burst mode in minutes. Increase this setting if you want a longer cool burst or decrease it if you want a shorter cool burst.

9. You can access the Bed Setup Screen by touching the Bed Setup button.

10. If you have more than one Perfectly Snug bed, then you can switch to a different bed by touching the 'Switch Beds' button.

11. Touch the wrench icon to access the Utilities Screen.

12. You can pull up helpful information about how to use the App by touching the question mark icon.

When your Smart Topper is not connected to your home WiFi, the App will switch your phone to a WiFi network created by the topper which is named based on your topper's Serial Number (example: PS123456). Your phone may ask you if you want to join PS123456 and you need to agree to join.

You can control your Smart Topper using this PS123456 network, but it is best to connect the Smart Topper to a home WiFi network using this screen.

1. You can go back to the Overnight Screen by touching the home icon.

2. When you first land on this screen, the topper will begin scanning for available WiFi networks. After a short delay, a list of available networks will appear. If your bed is connected to one of them, the App will show 'Connected' under it. If your topper is not connected to a network or if you want to change to a different network, then touch the network that you want your bed to connect to. If your home WiFi network doesn’t appear in the list, then swipe down on the list to re-scan for available networks. If it still doesn't appear in the list, then there is an issue with your WiFi network. It may be that your WiFi network signal is not strong enough where the topper is located. Note that the Smart Topper can’t connect to a 5 GHz WiFi network.

3. You can access the Advanced Network Settings Screen by touching the Advanced Settings button. In most cases it is not necessary to configure the advanced settings. It is only used in special cases where a home WiFi network is configured in such a way that prevents service discovery from working. If you are unsure of what this means, then it's best to avoid the advanced settings and contact customer service if you have trouble connecting.

4. You can pull up helpful information about how to use the App by touching the question mark icon.

5. After touching the network that you want the bed to connect to, a pop-up will appear. Enter your WiFi password and touch Connect. Be careful to enter your password EXACTLY. The password is CASE sensitive. You can cancel by touching anywhere outside the pop-up.

1. This screen will display a list of all previously connected beds. You can pick which bed to connect to by touching it. You can remove a bed from the list by touching the trash icon next to it.

2. If the bed that you want to connect to is not in this list, then touch the + icon to add it. This will bring you to the Setup Screen.
