Sleep Mat
This sensor transforms passive sleep into actionable recovery data — exactly what serious athletes need to optimize training and adaptation. Withings' clinical-grade monitoring (no wearable required) captures the metrics that actually matter: heart rate variability, breathing quality, and sleep architecture, giving you the insight to match your effort days with genuine rest days.
The Withings Sleep Mat is an under-mattress sleep sensor that delivers in-depth nightly analysis — including sleep cycles, continuous heart rate monitoring, snore detection, and breathing rate tracking — without anything to wear. One-time setup makes it compatible with most mattresses for effortless, passive sleep insight.
What the Withings Sleep Mat Supports in Your Nightly Routine
- Wearable-free sleep tracking: Slides under your mattress for passive, uninterrupted monitoring of sleep cycles and overall sleep quality via a nightly Sleep Score.
- Snore and breathing awareness: Detects snoring and tracks respiratory variations throughout the night, giving you a clearer picture of overnight breathing quality.
- Heart rate variability and recovery insight: Monitors continuous heart rate and HRV shifts to help you understand your body's response to stress and gauge how restorative each night was.
- Home automation integration: Connects with smart-home systems to adjust lights, temperature, and other settings based on your sleep state, supporting a more consistent sleep environment.
