A leader in sleep health and research, Sleep Number Corporation, has announced the results of their 360 Smart Bed study. The study results were presented at the 16th international meeting of the World Sleep Society in Rome. The study demonstrated that the smart bed could detect sleep stages in real-time and could help implement interventions to treat sleep disorders. 

The 360 Smart Bed is a mattress that shows sleep quality in the form of a SleepIQ score and also offers personal insights for better sleep through a smartphone app. The bed also features temperature balancing, pressure relief, comfort layers, and Smart 3D fabric that is 50% more breathable than typical beds, for a cooler sleep surface. The bed’s algorithm has the potential to detect sleep stages in real-time through cardiac data gathered while the person is asleep. 

Sleep Number also presented the results of a study aimed at detecting insomnia and other sleep disorders along with a prediction model that could predict and track symptoms associated with respiratory illnesses such as COVID-19 and influenza. All of these studies demonstrated the research potential for non-invasive, longitudinal studies to assess and monitor sleep with Sleep Number’s smart bed. 

The Sleep Number study used inter-beat intervals (IBIs) for real-time detection of sleep stages. IBI is the value between two heartbeats. Results showed that the smart bed algorithm had high specificity and moderate sensitivity for detecting sleep stages. The algorithm performed better in healthy sleepers as compared to individuals with sleep apnea. The results also showed that the smart bed could be used to detect the risk of sleep apnea, a sleep disorder that affects over 100 million people globally.
