SleepScore Max vs Withings Sleep Analyzer: Complete Non-Wearable Sleep Tracker Comparison 2025

Non-contact sleep tracking has revolutionized how we monitor our rest without the discomfort of wearing devices. The SleepScore Max and Withings Sleep Analyzer represent two distinct approaches to this technology, each offering unique advantages for different types of users. The SleepScore Max uses bio-motion sensing technology positioned bedside to track sleep through ultra-low power radio waves, while the Withings Sleep Analyzer takes an under-mattress approach with pneumatic sensor technology. Both devices promise clinical-grade insights without requiring users to wear anything, but they differ significantly in their sensor technology, data accuracy, and health monitoring capabilities.

  • FDA-cleared sleep apnea detection
  • Dual-user tracking with individual profiles
  • Completely invisible under-mattress design
  • GDPR compliant data handling
  • Clinical-grade health monitoring

Cons

  • Requires specific mattress compatibility

[OUR VERDICT]

The Withings Sleep Analyzer wins with its FDA-cleared sleep apnea detection, dual-user support, and superior user experience, despite lower sleep stage accuracy.

After extensive analysis of clinical data and user experiences, the Withings Sleep Analyzer emerges as the superior choice for most users, despite some limitations in sleep stage accuracy. The device's FDA-cleared sleep apnea detection capability alone justifies its position as a health monitoring tool rather than just a sleep tracker. This medical-grade feature can potentially identify serious health conditions that the SleepScore Max simply cannot detect.

The under-mattress installation of the Withings Sleep Analyzer offers significant practical advantages. Users report that it's completely invisible to guests and doesn't interfere with bedroom aesthetics. The dual-user tracking capability makes it ideal for couples, automatically separating data for each person - a feature entirely absent in the SleepScore Max.

However, the SleepScore Max does show better performance in basic sleep stage detection according to clinical studies, with moderate accuracy compared to the Withings' consistently poor sleep stage classification. For users primarily interested in understanding their sleep patterns rather than monitoring for health conditions, this could be a consideration.

Overall, the Withings Sleep Analyzer's combination of medical-grade sleep apnea detection, superior user experience, and dual-user functionality outweighs its sleep stage accuracy limitations. At nearly identical pricing ($149 vs $150), the medical monitoring capabilities and practical advantages make it the clear winner for health-conscious consumers.
