Sleep position trainer : Night Balance
How it works The Sleep Position Trainer (SPT) measures your sleep behavior continuously. Once you turn in to the supine position, this normally happens during lighter sleeping stages, the SPT gives a gentle vibration. This reminds you to change its sleeping position, without disrupting the natural sleep architecture. The SPT is worn in a comfortable torso strap around the upper body. In addition, the SPT comes with software to analyze the progress of the treatment.
