About
Sleep tracking has quietly become one of those health metrics everyone wants but few actually understand. Most people end up wearing something on their wrist all night, which defeats half the purpose of actually sleeping well. Withings approached this differently with their Sleep Analyzer mat, a thin sensor pad that slides under your mattress and does the heavy lifting without anything strapped to your body.
The setup is genuinely invisible once it's in place. It reads heart rate, breathing patterns, and sleep cycles through the mattress itself, then syncs with the Withings app to show you what actually happened during the night. The data presentation avoids the usual noise and focuses on what matters: total sleep, when you were in deep versus light stages, and how consistent your patterns are. There's also a snore detection feature that's surprisingly useful if you're trying to figure out whether that's actually a problem.
This lands somewhere between casual wellness and serious sleep optimization. It works for anyone curious about their sleep quality without wanting the commitment of a wearable, or for someone sharing a bed who wants to track their own data without syncing their partner's movements into the equation.
