Frequently asked questions
How can a pad track sleep?
Pneumatic sensors read micro-movements, heartbeat and breathing through the mattress — no contact needed. Accuracy rivals wrist wearables for staging and beats them for snore/breathing detection.
Does it detect sleep apnea?
It flags breathing-disturbance patterns and is CE-marked for apnea detection in Europe (not FDA-cleared in the US). A strong screening signal, not a diagnosis.
Two people in the bed?
It tracks the side it's under — buy two for a couple, or place under the sleeper who wants data.
Subscription?
None — all metrics free in the Health Mate app, unusual and welcome.
