The fitness tracker is useful, but it can’t give you the holistic or detailed analysis that dedicated sleep monitors can. Emfit are a Finnish company who’ve been in business for decades but the evolution of home wifi and smartphones have given them the opportunity to create consumer friendly products more likely to be used by you and me.
The Emfit QS is one such gadget that’s designed to seamlessly integrate in to your nightly routine and give you feedback on your sleep. The device itself arrives in a small box and isn’t actually a mattress but a strip of synthetic leather that’s placed under your mattress. As well as the sensor strip, which has a power lead attached is a mains adapter.
Setting up the Emfit is reasonably straightforward. Unusually it doesn’t use Bluetooth, but Wifi to connect to your home network and the Emfit servers. I needed my Wifi password and the Emfit’s unique code to register it online, but it was quickly up and running.
The positioning of the sensor strip itself is important. It’s about half the width of a double bed and needs to be placed under the mattress. There is no contact between you and the gadget, instead it used incredibly sensitive sensors to monitor your sleep. I placed it under the mattress roughly level with my chest to ensure the cardio readings were accurate.
Once the device is powered up and positioned, I forgot about it for a couple of days. I find devices like these don’t tell you anything useful until you have a few days or even weeks of information to review. When I signed in online and connected to my account though, the broadness of what the Emfit can tell you becomes apparent.
The data is presented clearly and in chart form. As well as telling me how long I slept each night the data also shows the class of sleep from deep to light and even REM sleep. My breathing was also monitored every night and my heart rate was recorded. One of the most interesting statistics is how much you move during the night with any tossing and turning recorded.
There is more technical analysis available including heart-rate variability and athletes can use the data to review their recovery from exercise. For the average user though the data the basics that the Emfit records would be enough and there’s a useful daily wellness report.
The sleep data is presented using the Emfit website and while it looks good I think a dedicated app would be useful. Also, the device is made for one person whereas a bigger, double bed version would let a health conscious couple keep an eye on their sleeping stats.
