With the innovative UB 190 CosyNight comfort underblanket from Beurer and the accompanying Beurer CosyNight app, you can conveniently control your underblanket at home or on the go using your smartphone. The app allows you to set a timer, reset the temperature, or create custom heating programs for each day of the week. The stretch underblanket is particularly comfortable due to its cotton surface. For personalized use, there are separately adjustable temperature zones for the body and feet, each with nine temperature settings. For hygienic and easy cleaning, the heated underblanket can be machine washed at 30 °C.
