Sleep Analyzer
Withings Sleep Analyzer is a sleep mat from 2020, sitting in the mid-range band at an indicative $199.
It reads 7 of the 33 signals this comparison tracks. Full coverage of sleep. Nothing at all from activity, fitness and body composition. Rarer readings it does take: sleep apnea screening and sleep efficiency.
By sensor class: 1 at clinical grade and 6 at high accuracy. That grade is my classification of the hardware, not a lab test. Those readings come from an accelerometer.
It weighs 350 g. No subscription is required.
Under-mattress mat; sleep duration/stages/score, HR, resp rate, snoring, validated apnea detection.

Turn a supported wearable into daily health scores
MyBodyAI reads Fitbit, Oura, Polar and Withings by logging in, and Garmin from a data export, then builds daily recovery, sleep, load and immune scores, a biological age estimate, and early warnings. Optional, and separate from this comparison.
This comparison is free and ad-free. I build and update it on my own. If it saved you hours of research, a coffee genuinely makes my day.
