Humantechnik's vibrating contraption is the strongest and most intensive way to be woken up reliably and safely. This powerful and robust vibration system is firmly attached under the slatted frame or spring frame of your bed. The wake-up alarm is translated into powerful vibrations that are transmitted through the mattress.
The Humantechnik vibrating contraption is available in two different versions:
Model A: for direct connection to all current Humantechnik alarm clocks
Model B: for use with timer switches and smarthome power outlets
