Sleep Analyzer
The Withings Sleep Analyzer is the best non-wearable option, utilizing ballistocardiography (BCG) to measure heart rate, respiration, and movement through the mattress. It is uniquely clinically validated to detect sleep apnea.
Quality & Materials
A low-profile pneumatic sensor pad wrapped in high-quality fabric. It sits under the mattress at chest level and connects via Wi-Fi.
Evidence & Testing
Clinically validated for sleep apnea detection with CE medical marking in Europe and high correlation with PSG for sleep cycle analysis.
Brand Transparency
Withings provides clear documentation on their BCG technology and has been involved in numerous clinical trials for cardiovascular health.
Value Assessment
At $129, it is the best value for users who only care about sleep tracking and do not want to deal with charging a wearable device.
Why Not Alternatives?
Unlike Oura or Apple Watch, it requires nothing to be worn on the body, making it ideal for those who find wearables uncomfortable. It is significantly more affordable and offers medical-grade apnea detection not found in most consumer devices.
