The LEFT Device: How it Works

The LEFT Sleep Position Training Device is easy to use and will teach you to sleep predominantly on your left side and prevent nighttime heartburn pain. Make sure to use the associated stickers with the device every night for optimal results.

Let’s get started!

… with these simple steps.

1. Clean

Make sure your breastbone area is clean, dry and free of hair.

2. Peel

Remove a sticker from the sheet.

3. Stick

Attach the exposed side (with the red tab) to the LEFT Device.

4. Turn on

Press the button for approximately 3 seconds. The LEFT Device will vibrate 3 times.  

5. Wear

Peel the skin side tab off the sticker and place the LEFT Device in the middle of your breastbone area. The LED light must be at the top center of the device.

 

6. Sleep

The LEFT Device will confirm its activation by vibrating exactly 1 minute after being turned on.


The LEFT Device will auto-start 20 minutes after being turned on, giving you the time to fall asleep.

 

TIP!

To check that your LEFT Device is turned on, the blue light should flash when you press the on/off button.

And while you're sleeping:

  • Your nighttime heartburn symptoms will be eliminated or significantly reduced
  • You will (finally!) enjoy painless restful nights, which leads to …
  • … a vastly improved life

To turn off:

  1. Carefully peel off the LEFT Device and dispose of the sticker.
  2. Press the power button. The LEFT Device will vibrate for a few seconds, indicating that it has powered down.

The LEFT Device also turns off automatically after eight hours.
