Fitness tracking has almost exclusively taken the form of wrist-worn devices that record vital stats about your heart rate and activity during sleep. Sleep is vital to overall health and this under-mattress sleep monitor is definitely geared towards athletes, recording the kinds of data you would expect from professional fitness regimes. Yet this is a device that could be used by anyone who has serious concerns about the amount and quality of sleep they get and how it relates to their overall health. We pitted the Apple Watch against other popular fitness trackers in our Get Fit feature on page 74, but we couldn’t add sleep quality into the mix; the Apple Watch can’t record that.
Though some wristbands track sleep, such as the Jawbone Up, a static strip that’s more part of your bed than part of you is surely the better indicator. The tech inside the QS is comprised of electroactive polymers laid out in a strip that has two adhesive tabs that stick to the underside of your mattress, whatever its depth. Connected to that is a wireless element that communicates with your router. We had some problems setting it up, but resetting the router and using the WPS method resolved that. Emfit says it hopes new firmware for the QS will address issues with some routers.
The QS has no buttons, and you can’t really configure anything in its web interface. But you’re supposed to just let it do its analysis – it knows as soon as you jump into bed and starts monitoring. It’s serious science, with three-stage sleep classification in addition to total duration. You’ll see percentages of REM, light and deep sleep tracked alongside heart rate, respiration rate and physical activity – yes you really are that fidgety at 4am! We can’t verify these recordings scientifically, but to see your night’s sleep plotted this way is a real eye-opener. Christian Hall
A wealth of sleep data. Probably far too much for most people, but there’s nothing quite like it found elsewhere.
The Emfit QS aims to help you better understand your sleep and how it affects your health.
