About us

Side Sleep technology BV

SIDE SLEEP TECHNOLOGIES BV is a Dutch digital health startup using the latest wearable technology to train people to sleep on their side to improve their sleep quality and reduce health problems during the night. 

We believe that great sleep helps you to live fully and be the best version of yourself. For this reason, we leverage on the latest wearable technology to create solutions that are research-based, affordable, easy to use, and non-invasive.


To offer an efficacious patented non-invasive solution that will eliminate nighttime heartburn reflux symptoms by using sleep positional therapy

Our first release

Our first release, the Snooor Anti-Snoring wearable using the principles of positioning therapy combined with wearable technology, was developed to train positional (back) snorers to sleep on their side so they can breathe more freely and stop snoring!

Our second release

Our second release is the Left Device which trains people suffering from acid reflux to sleep on their left side so the stomach is positioned below the esophagus and gravity works to keep acid in the stomach and the pain goes away.

Our latest innovation

Our latest innovation is The Left App that tracks sleeping body position on the apple watch to train users sleeping more on their left side. 

The Team

Our team is made of leading sleep experts and technologists working together to help you sleep better.
