Withings Sleep Tracking Mat

Clinical-grade sleep tracking without wearing anything to bed. The Withings Sleep mat slides under your mattress for a one-time setup, then works invisibly every night — automatically syncing results to the free Health Mate app by the time you wake up.

Key Features

• Nothing to wear — Slim 5mm mat installs under most mattresses in minutes. No wristbands, no chest straps, no charging nightly.
• Advanced sleep tracking — Monitors full sleep cycles (deep, light, REM), continuous heart rate, and snoring. Generates a Sleep Score so you know how restorative your night actually was.
• Breathing quality assessment — Tracks overnight respiratory patterns to flag potential disturbances — a key indicator of restful, restorative sleep.
• Heart rate variability (HRV) — Measures your body's response to stress overnight, helping you adapt your activity and rest routines to improve recovery and resilience.
• Breathing rate monitoring — Detects respiratory variations that may signal nocturnal breathing anomalies or sleep disturbances.
• Movement detection — Captures the intensity and frequency of body movement throughout the night to identify sleep fragmentation.
• Smart home integration — Triggers connected lights, thermostats, and other smart home devices automatically when you get in and out of bed.
• Shareable sleep diary — Auto-generates a medically-informed sleep report you can share directly with your doctor.
