Withings Sleep Analyzer

The Withings Sleep Analyzer is a sophisticated under-mattress sleep tracking pad that monitors your sleep patterns without requiring any wearable device. Measuring approximately 24 inches long, 7.5 inches wide, and just 0.2 inches thick, the ultra-thin mat slips beneath your mattress and uses pneumatic sensors to detect respiratory rate, heart activity via ballistocardiography, and body movements throughout the night. Compatible with most mattress types (spring, latex, foam, memory foam) from 10 to 45cm thick.

The Sleep Analyzer provides comprehensive sleep cycle analysis including light, deep, and REM phases, delivering a daily Sleep Score along with detailed metrics on heart rate, heart rate variability, respiratory rate, snoring duration, and nighttime movement. In the EU, it's recognized as a medical-grade device capable of detecting moderate-to-severe sleep apnea by analyzing breathing patterns and reporting the Apnea-Hypopnea Index (AHI). Note that sleep apnea detection is pending FDA approval in the US.

Smart home integration through IFTTT enables automation triggered by getting into or out of bed, such as dimming Philips Hue lights, adjusting thermostat settings, or muting your phone. Amazon Alexa integration allows you to ask how you slept the previous night. All data syncs to the Withings app (iOS 16+ or Android 9+) with free unlimited cloud storage and up to 30 days of history for tracking trends. The device requires a nearby power outlet and 2.4GHz WiFi connection.
