Hi Scarlett, this is a great question! While UPRIGHT GO2 is designed to be used on your spine, to detect your back movement, it can also be used in other locations. If you feel like you're sitting straight, but your shoulders fall forwards too much, we have something you can try out. Please reach out to us at email@example.com, the in-app chat or on our website's chat and we'll be happy to instruct you further. Thanks, Upright team.
